Normally Open Switch

Normally Closed Switch

Double Pole DoubleThrow Switch

Double Pole Switch

Switch OperationNormally Open - A normally open switch will has the contacts disconnected during the normal, machine OFF andunattended state. For instance, a dome lamp switch would typically be turned OFF when the machine is left unattended.Therefore, the switch to operate the dome lamp would be shown normally open on the schematic.

Normally Closed - A normally closed switch will have the contacts connected during the normal, machine OFF andunattended state. This is less common than a normally open switch. An example of a normally closed switch would be thePrelub oil pressure switch.

Double Pole - This is a switch that switches power form one terminal to the other. In the example to the right, terminals 4and 5 are normally open and terminals 5 and 6 are normally closed.

Double Throw - This is basically 2 switches connected together so they switch together.

Double Pole Double Throw - The is 2 double throw switched connected together so they switch together. In the example, 1and 2 are in contact, and terminals 4 and 5 are in contact during the normal state. When the switch is switched, terminals 2and 3 are in contact, and 5 and 6 are in contact.

Relays and Magnetic SwitchesA relay is a magnetically actuated switch. A coil in the relay is energized by passing current through it (terminals 1 and 2on the double pole relay to the right). This pulls the switch toward the coil switching it just like a manually operatedswitch.

A magnetic switch is a large relay which opens or closes both terminals at the same time. These are generally used to turnON and OFF high current circuits with inductive loads such as starters, supplemental steering pumps, Pre-lubricationpumps, and other large electric motors.

General Troubleshooting HintsVoltage TestsVoltage tests are made on a "live" circuit. This means the circuit must be powered up. The voltmeter is connected to that the positive lead is attached to the portion of the circuitwith higher voltage and the negative lead to the lower voltage portion. In most cases, this means the positive lead is connected to the circuit component or wire, and the negativelead is connected to a good ground such as the battery negative terminal.

Volts

- +

Test LightTest lights are used just like a voltmeter except polarity is not important. The intensity of the light is related to voltage. The brighter the light, the more voltage is present. Testlights respond to voltage changes instantly making them a good choice for wire harness "wiggle checks".

Ohm TestsOhm (or resistance) tests must be made with the power disconnected from the circuit. These tests are generally used for testing components rather than circuits. For instance, youcan test the function of a switch with an Ohmmeter.

Open CircuitsOpen circuit - Part of the circuit no longer has a connection to the rest of the circuit. Current will not flow in this circuit. The break can be anywhere in the circuit including theground path between the battery and the ground point of the component (the lamp in the case below).

Open circuit

Even with the switch turned ON, nocurrent will flow to the lamp.

Open circuit faults can be the most challenging. They don’t blow fuses or trip breakers and they can’t be traced with a tool like the short finder. There are open circuit fault findersavailable on the market however these are unreliable when used on most machines or engines. The trick here is to narrow down the fault to the point where the open exists. Poorconnections at connectors are often the culprit however wires can fatigue and break in the insulation as well. Be particularly suspicious of areas in the harness that move or vibratein operation. For instance, the wiring harness between the engine and the chassis will have movement. Use connector probes to check for proper signal at the various connectionsrelated to the circuit of interest. You can then narrow the open down to the section of circuit where the signal is lost.

Short CircuitsShort circuit - The circuit path has been shortened by current flowing in an unintended path. This usually involves a rubbed-through wire, damaged connector terminals, or faultycomponent. A short to ground will cause excessive current and will activate the circuit protection device (fuse or breaker would blow/trip) if one exists in the remaining circuit. Ashort to power will cause the affected circuit to be powered up at the wrong time and added current in the circuit it is shorted to.

Short to ground

When the switch is turned ON,current will flow directly to ground,

bypassing the lamp. This is ashorted circuit.

Short to power

The lamp will be ON at all times due to the harness short feeding thelamp from the upper breaker.

For non-ECM input circuits, shorts to ground will generally cause a fuse to blow or breaker to trip. In some cases it will just switch a device ON. There are several short findersavailable from most tool distributors such as Mack, Matco, and Snap-On. These short finders have a magnetic field sensor in them. When current passes through a wire, amagnetic field is generated. The short finder has a needle that will indicate the strength of this magnetic field. When a short causes additional current to flow, the needle willdeflect. The short finder kit also includes a small circuit breaker so that current will pulse on the circuit. Every current pulse will cause the needle to deflect. You can follow theharness while making the short occur and watch for needle deflection. When you pass the shorted area the needle will stop deflecting. Using this method you can narrow downthe problem to a particular area.

Snap-On Short Finder

Shorts to power or other circuits can be handled somewhat similar except the problem will be between 2 or more wires rather than between a wire and ground. Look for damagedor overheated wiring. Look for wires where the insulation has had fluid on it.

Intermittent FaultsMany, if not most, electrical or electronic system faults on modern equipment is intermittent in nature. This means that normal test procedures designed for constant (hard) faultswill likely be ineffective. Test measurements made while the problem is not occurring will generally result in normal readings. There are several things one can do to chase theseillusive faults down. The following information is some of the strategies that have been found to be effective in real world troubleshooting.OKTOPUS

CELL 000-10 HOW TO USE THIS MANUAL

924G ELECTRICAL HYDRAULIC SUBSTYSTEM MANUAL CATERPILLAR INC.

The first thing you need to do for any intermittent fault troubleshooting is to verify the operators’ complaint. In some cases the operators’ complaint may be normal operation. Itis important that you communicate with the person who actually experienced the fault to get a clear understanding of exactly what his/her concern is. Once you have determinedthat the complaint is not normal operation, you must operate the machine to learn how to make the fault occur. It is very important that this be done before you touch anything.Do not wiggle wires, check connections, take readings, or anything until you have verified the complaint and learned how to duplicate it. The reason is that you could temporarilycorrect the condition without knowing it. This leads to repeat repairs. Generally, in order to duplicate the fault you should ask the operator questions such as these:

1. How often does the fault occur?2. How are you operating the machine when it occurs? What is turned ON and what is OFF? What gear is it in? Where is the engine speed? How much engine load?3. Does it always occur under a given set of conditions or is it completely erratic?4. Did it start all of a sudden or did it slowly get worse over time?5. What is the ambient temperature when it occurs?6. What is the engine temperature when it occurs?7. What is the weather like when it occurs? Rain, snow, wind, humidity, dust, etc.8. How long after start-up does the problem begin happening?9. Are there any other problems with the machine?10. When was the machine last worked on and what was done?11. How is the machine oriented when the fault occurs? Are you heading uphill, downhill, slope to the left or right?12. What time of day does it generally occur? Morning, night?13. Any other information about conditions during the fault.

This information will help you duplicate the fault. Even better than gathering this information is to simply ride with the operator while the fault is occurring. It is better to let theoperator show you the fault than to operate the machine yourself, at least initially. If the symptoms are related to an electronically controlled system, check for, record, and clearany fault codes before verifying the concern. Doing this will ensure you have no logged faults to begin with and if you get any codes later, you will be relatively certain they areassociated with the fault. This information can also help you narrow down the most likely areas for the fault. For instance, if it only happens under heavy engine load, the suspectarea might be the harness or connections between the engine and chassis.

Once you have verified the fault and can duplicate it, you are ready to start testing. If the symptoms are related to an electronically controlled system the first thing to do is checkfor fault codes. If a fault code is now present (after clearing it before the verification process) it is likely associated with the customers complaint. The fault code will give you anindication of what circuit the problem is in. Non-electronic systems can usually be narrowed down to a circuit by the symptoms. For instance, if the flood lamps flicker, youalready know it is a flood lamp circuit fault.

It is important to make an effort not to disturb anything to make these tests. Use the connector spoons (7X-1710) to connect into the circuit.

It is generally best to start testing at the circuit level and narrow down to the component or harness. For instance, if you have a 3-wire analog sensor circuit, you should start bytaking readings at the ECM connector between signal return and the signal wire. Avoid testing between signal wire and chassis ground. You will also need to check the voltagereference wire to signal return.

Here is where experience will really help you determine where to start testing. If you have had several occurrences of a particular harness or connector fault, check for that first.Since you have already verified and duplicated the fault, you may be able to go right to the suspect area and inspect for the problem. Cat Diagnostic Advisor (CDA) can reallyhelp here. CDA has a wonderful feedback tool that will form a communications link between Cat mechanics all over the world and Cat service engineers. A mechanic in Seattlemay find a strange problem with a ground circuit on a particular machine and he can send that information to Cat who broadcasts via CDA to the world. This could savesignificant time for the rest of the mechanics faced with the same symptoms. It is also important to check Service Magazine, TIB's, service letters, and other periodicals beforegoing too far. There may be an article about the problem you are having along with a solution. Always check these things before beginning your testing. Keep in mind this doesnot eliminate the need for verification and duplication!OKTOPUS

Having a good understanding of the operation of the system is a must. You don’t really need to know details of what goes on inside the ECM but you do need a goodunderstanding of what to expect for a signal on a particular wire for a given set of conditions. For ECM inputs it is also important to understand what symptoms will occur if thesignal is not correct. This information will help lead you from a symptom to a possible cause before you begin testing. Most ECM input faults will cause several outputsymptoms. If you understand the relationships you can become fast and proficient at intermittent fault troubleshooting.

Keep in mind there are many hydraulic and mechanical systems associated with most machine functions. Just because a fault is intermittent does not mean it is an electrical orelectronic fault. DataView (Cat Part# 131-5051) is particularly helpful here since it can record these temperature, pressure, an other readings along with electrical readings to helpsort this out. Just because a sensor reading goes out of range does not mean it is bad. It could be whatever it is sensing is actually out of range. For instance, if a temperaturesensor has a normal range of -40F to 250F, a fault code will appear if it reads 275F. It is very possible whatever it is sensing is actually that hot. Don’t change the sensor if it is notat fault. If the problem has gotten progressively worse over time, look for things that could be wear or contamination related. Think about what things would get worse over timeand target those areas first.

Since the condition is intermittent you will need to take the readings while the problem is occurring. There are several methods for doing this. The best tool for this is a strip-chartrecorder or a data logger that will give you a graph of voltage (y-axis, or vertical axis) and time (x-axis or horizontal axis). DataView has the ability to do this one input at a time.Another method is to use a DVOM with a min/max record feature. The Fluke 87 has this capability. Another method is to have the operator duplicate the fault while you aremonitoring the voltage levels. For simple electrical circuits (non-ECM inputs), a test light will actually work even better for the last method. A lab scope with capture capability isideal for this. Fluke makes the Scopemeter (Cat Part# 152-7213) which is 2 channel with capture capability. The more channels the better. If you have a 10-channel scope forinstance, you can simultaneously test 10 points in the system. All it would take is one occurrence of the fault to see the 10 different points in the system. ET also has data loggingcapability that is useful. Keep in mind however, ET can only tell you the ECM’s interpretation of what the ECM is reading at the pins of it’s connector. It cannot narrow the faultdown to a harness or component.

Intermittent Short CircuitsNow that you have narrowed down the problem to a particular portion of the circuit, you can begin more detailed testing to find the root cause. Say for instance you have an oiltemperature fault code and you found that the signal wire intermittently drops to almost 0 volts while the sensor power supply and ground circuits are OK. At this point you wouldsuspect a harness short to ground or a faulty sensor. Connect the DVOM to the signal wire at the sensor or ECM and carefully wiggle and pull on the wiring harness. If theharness passes over a metal surface, push it against that surface to see if the voltage drops while you are pushing. Once you do get the voltage to drop, you can inspect that area fordamaged wiring.

For non-ECM input circuits, shorts to ground will generally cause a fuse to blow or breaker to trip. In some cases it will just switch a device ON. You can install a small breakerin the circuit in place of the fuse for testing. Wiggle and pull on the wiring in the suspect harness until the breaker trips. When the breaker trips, you are in the area of the fault.Inspect that area for damaged wiring. Sometimes it is helpful to have a test light connected to the wire in question. The light will flicker when the short occurs.

Shorts to power or other circuits can be handled somewhat similar except the problem will be between 2 or more wires rather than between a wire and ground. Look for damagedor overheated wiring. Look for wires where the insulation has had fluid on it.

There are several short finders available from most tool distributors such as Mack, Matco, and Snap-On. These short finders have a magnetic field sensor in them. When currentpasses through a wire, a magnetic field is generated. The short finder has a needle that will indicate the strength of this magnetic field. When a short causes additional current toflow, the needle will deflect. You can follow the harness while making the short occur and watch for needle deflection. When you pass the shorted area the needle will stopdeflecting. Using this method you can narrow down the problem to a particular area.

Intermittent Open CircuitsOpen circuit faults can be the most challenging. They don’t blow fuses or trip breakers and they can’t be traced with a tool like the short finder. The trick here is to narrow downthe fault to the point where the open exists. Poor connections at connectors are often the culprit however wires can fatigue and break in the insulation as well. Be particularlysuspicious of areas in the harness that move or vibrate in operation. For instance, the wiring harness between the engine and the chassis will have movement.

Start by monitoring the signal at the very end of the wire. For instance, if the fault is in a temperature sensor signal circuit, monitor the signal wire at the sensor. Carefully wiggleand move the wiring harness and connections until the signal is interrupted. Once the signal is interrupted and you figure out how to make it happen, move the DVOM to the nextconnection before the sensor and wiggle again. Eventually you will pass the faulty area and the signal will not interrupt. The fault will be between the last 2 points. If the wiresare exposed in this area (no braid) you can pull on them to see if the wire is broken in the insulation or not properly crimped in the connector. Also look for connector terminalsthat are not fully inserted into the connector body.

Other Intermittent FaultsThere are other faults that can cause strange behavior of the machines electrical and electronic systems. Most of these are associated with aftermarket equipment. If 2 wires areplaced parallel to each other one wire can induce a voltage in the other. The more distance the two wires travel together, the worse it will be. Generally this is only a problemwhen a very high impedance circuit is placed parallel to a very high current circuit. For instance, a starter cable running parallel to a sensor circuit. Circuits that power inductiveloads are even more likely to cause a problem. Examples of inductive loads are starters, fan motors, supplemental steering motors, horns, large relays (or magnetic switches), andstarter solenoids.

Large inductors can also cause problems in other electrical circuits even when the wiring and connections are all good and the wires are not run parallel to other wires. Whathappens is that when voltage is removed from a large inductor, the magnetic field collapses causing a voltage spike in the electrical system. This voltage spike can jump acrossswitch and relay contacts. In some cases, a clamping diode is needed to stop the voltage spike from affecting other circuits. The AC compressor clutch is a good example of alarge inductor where a clamping diode is generally used. Again, these problems are usually associated with aftermarket components that cannot handle voltage spikes.

Moisture can cause an intermittent path for current flow as well. This is especially true for water-based fluids and even more so for acids (like battery acid). Battery acid can soakthrough the insulation on a wire and allow current flow to ground or to other nearby wires. This may only happen when the wires are wet and the current may stop when they dryout. This current flow will generate heat. The more current the more heat. Occasionally you can actually feel the heat build up in such areas. A non-contacting thermometer(148-2400) can help trace these problems down by finding the hot spots. If the problems only occur in wet or very humid weather, or only first thing in the morning, this is a likelycause.

Keep in mind that solid state electronics really don’t wear out. In fact, solid state electronics tend to have more problems early, than after many hours of use. Don’t replace solidstate electronics as a maintenance item. There is no maintenance on solid state electronics. Installing new ECM’s, temp sensors, or other solid state electronic devices couldactually increase the probability of a failure. Replace failed components only.

Repair and VerifyOnce you have narrowed down the problem to a harness, connector, or component, make the repair and verify it has corrected the initial complaint.

This strategy may seem cumbersome and long to some but as you become proficient at it, the time reduces drastically. You will have more successful repairs on a single visitwhich will save time and improve customer satisfaction in the long run.

There are some faults that occur so infrequently that it is almost impossible to verify or duplicate them. If these faults do not cause a safety concern, it is best to let them get badenough so that they can be duplicated before trying to troubleshoot them. Again, make sure you check CDA, Service Magazine, and other periodicals to see if the symptomsmatch. OKTOPUS
