Charging systemThe charging system provides electrical current for the lights, radio, heater blower

and the engine’s electrical systems. It also maintains the batteries in a charged state,

recharging them as necessary to provide cranking power.

The charging system has three main components, or component areas: the alter-

nator, the voltage regulator, and the battery.

The alternator is driven by a belt from the engine crankshaft and produces the

electrical power to operate the systems on the bus. It also recharges the battery.

The voltage regulator acts as a “control valve” for the alternator output. It senses

the current load and maintains a constant voltage in the charging system, indepen-

dent of the current load, up to its rated output. The Leece Neville™ alternator on the

Blue Bird Vision has a “built in” voltage regulator. It is excited (started) by the ignition

system.

The battery is the reservoir of chemical electrical power. Its primary purpose is to

crank the engine. It also supplies power to the accessories for a short time when the

demand is too high for the alternator alone (i.e., while the bus is at idle). Another key

role of the battery is to act as a filter for the charging system.

The Blue Bird Vision has a 12-volt electrical system. The alternator is a 175-am-

pere, 12-volt device. Leece Neville model number A0014834LC is standard.

MaintenanceClean the alternator and all connection points. Dirt buildup restricting air flow

through to the alternator will cause excessive heat and premature failure. Corrosion

at any connecting point will produce resistance to current flow, heat and diminished

power for the starter and accessories.

Ensure that all the components in the charging system are mounted securely.

Check the torque at all mounting bolts — both the bolts that hold the alternator in

the mounting bracket and the bolts that secure the mounting brackets to the engine.

The torque value for mounting bolts at the engine and at the alternator should be 70

– 80 ft lb (95 – 108 Nm)

Blue Bird Vision buses are equipped with an automatic belt tensioner. Ensure

that all the grooves fit properly into the pulleys in the correct path. The drive belt

should be inspected every 11,000 miles (17,700 km), 250 hours of service life, or ev-

ery 3 months; whichever occurs first.

Also check:

• Battery voltage

• Alternator output

• Starter current draw

troubleshootingTimely preventive maintenance of the charging system should keep it running

smoothly. However, when a problem occurs, effective troubleshooting procedures

will help locate and correct the problem quickly and economically.

[Warning] Batteries emit an explosive gas. Never smoke while working on

the charging system. Batteries can explode from a spark. Always remove the

negative battery cable at the battery post before removing any other wires in

the charging system. Be careful not to short the system while you are working

on it. Do not wear jewelry.

Before you begin to analyze the charging system, it is necessary that you ensure the

battery is properly tested and charged to at least 75% of their rated capacity. Failure

to confirm the condition of the battery will make the results of any diagnostic testing

unreliable. Refer to the battery manufacturer’s publications on battery maintenance

and testing.

Alternator Performance Test

1. Connect a digital volt/ohmmeter (VOM) to the output ter-

minals of the alternator.

[Caution] Ensure that the test leads are connected prop-

erly. Observe the polarity and make secure connections.

2. Connect an ammeter to the positive terminal of the alter-

nator. Observe that the clamp on the ammeter is located

at least 6 inches (15 cm) from the alternator to lessen the

possibility of faulty readings due to spurious emissions.

3. Verify that the voltage output from the alternator is be-

tween 13.6 and 14.2 volts with the engine at operating

RPM (1700 RPM minimum) and not idle.

4. Ensure that all “loads” are in the off position. The reading on the ammeter

should be less than 20 amps.

• If the amp reading is higher than 20 amps, ensure all accessories are

turned off.

• Ensure the battery is charged to at least 75% of their rated capacity.

5. Record the voltage. If the voltage is not within the specified range or the

amperage is not within the specified range, the alternator is defective.

6. If the alternator is determined to be defective, repair or replace it in accor-

dance with the instructions below. See Alternator Removal.

7. If the alternator is determined to be functioning properly, proceed as fol-

lows:

8. Continue to operate the engine at about 1700 RPM, and with the test equip-

ment set up as illustrated.

9. Turn on vehicle loads (accessories) until the ammeter displays 132 amps,

which is 75% of the rated capac-ity (175 amps). Record the voltage at this

point.

10. Compare the voltage reading with the voltage reading observed in Step 3

above.

11. If the alternator voltage drops more than .5 (1/2) volt, the alternator is defec-

tive.

An alternate method of checking the alternator under load is to use a carbon pile

load. Connect the carbon pile across the battery and adjust it until the ammeter

reads 75% of the alternator rated capacity. Record the voltage at this point, shut off

the engine, and compare the readings.

Alternator Cable Tests

To test the positive alternator cable:

1. Clamp the ammeter on the positive cable at least 6

inches (15 cm) from the alternator. See Figure 2.

2. Connect the negative lead of the VOM to the positive

post of the alternator.

3. Connect the positive lead of the VOM to the positive

battery post.

4. Start the engine and let it run at about 1700 RPM.

5. Turn on accessories until the ammeter reads 132 amps,

which is 75% of the rated alternator capacity (175 amps).

Use a carbon pile if necessary to achieve the load.

6. Record the voltage reading on the VOM.

7. If the VOM reads more than -.25 volts, there is a problem

with the positive cable.

• Check and clean all the connections and the condi-

tion of all the cables/wires in the circuit.

• Re-test the circuit.

8. If the reading is less than -.25 volts, the cable and con-

nections are good.

9. Connect the lead negative of the VOM to the negative

terminal of the battery.

10. Connect the positive lead of the VOM to the negative

terminal of the alternator.

11. Repeat Steps 4 through 8 for the negative cable.

Bosch alternator removal

[Warning] Always disconnect the negative (-) cable from the bat-

tery terminal first to avoid arcing, which could ignite explosive battery

gases.

1. Park the bus on a smooth, flat surface.

2. Chock the wheels in both directions.

3. Ensure the engine is not running, the ignition switch is in the “OFF”

position and the key is removed.

4. Disconnect the negative (ground) cable from the battery

post.

5. Lift the automatic belt tensioner to remove the drive belt

from the alternator.

6. Remove the drive belt.

7. Inspect the drive belt; discard it if any signs of wear are present.

A few minor cracks across the belt are acceptable. Longitudinal cracks are NOT ac-

ceptable. Replace the drive belt when any crack is observed to be running length-

wise or with the belt, or when the belt appears frayed.

[Warning] Always disconnect the negative (-) battery cable at the battery

before removing any wiring from the alternator.

8. Remove the negative (-) cable from the alternator.

9. Remove the positive (+) cable from the alternator.

10. Remove the bottom mounting bolts.

Alternator Reinstallation

Installation of the alternator is accomplished in the reverse order of the removal in-

structions above.

1. Position the alternator and install the top and bottom bolts. Torque bolts to

33-35 ft. lbs.

2. Install the positive cable on the positive (B+) post. Carefully tighten to avoid

breaking or stripping the stud.

3. Install the negative cable on the negative (B -) post. Carefully tighten to avoid

breaking or stripping the stud.

4. Using a square drive tool, position the automatic tensioner so that the drive

belt can be installed. Inspect the drive belt carefully. Replace the belt if any

signs of wear are present.

5. Install the drive belt. Ensure that the grooves in the belt fit into the proper

places on all the pulleys.

6. Start the engine and test the alternator output.

729

L


automatic Belt tensionerThe automatic tensioner is spring loaded to provide the proper tension for the drive

belt.

The automatic tensioner should travel at least 71º, and the torque to move the

tensioner 25º from the “at rest” position must be 9 – 11 ft lb (12.4 – 15.8 Nm). In-

spect the belt tensioner for any unusual noise, excessive looseness and shaking at

the bearings.

Automatic Tensioner Removal

1. Remove the drive belt in accordance with the instruc-tions above.

2. Remove the capscrew (1) from the automatic ten-sioner. See Figure 8.

To install a new automatic tensioner, reverse the removal instructions. Torque the

capscrew (1) to 28 – 42 ft lb (38 – 56 Nm).

starterThere are 5 main components or component areas in the starting system: the igni-

tion switch, a neutral safety switch, the starter solenoid, the starter motor and the

batteries.

When the key is turned to the start position, electrical current flows to the starter

solenoid from the batteries. The flow is interrupted if the transmission shift lever is

not in the neutral position or if the neutral sensor switch is defective.

The starter solenoid is an electromagnetic switch mounted on the starter motor.

When electric current energizes coils inside the solenoid, a magnetic field is induced

which pulls a plunger. At one end of this plunger is a shift lever. The lever is con-

nected to the drive pinion and clutch assembly of the starter motor. The plunger also

connects the electrical power from the batteries to the starter motor as it engages

the flywheel ring gear.

The starter motor is a relatively small electric motor, but it can deliver large

amounts of torque for a short time.

When the operator releases the ignition switch it returns to the run position. The

solenoid is disconnected from the batteries and the magnetic field collapses. This

allows the spring in the solenoid to move the plunger in the opposite direction, dis-

engaging the flywheel and removing electrical current from the starter motor.

The Blue Bird Vision has a 12-volt electrical system. The starter motor is Model

35261110, Presto-lite/Leece/Neville M100R series. The Starter motor is capable of

4kw cranking power for peak loads of no more than 30 seconds duration.

Preventative MaintenanceThere are two preventative maintenance procedures that can greatly enhance the

efficiency of the starting system. These two steps are also the first two steps taken

when troubleshooting a malfunctioning starting system.

• An engine that needs a tune up will be difficult to crank; over cranking will

lead to starter motor failure.

• Poor connections due to road dirt, grease, corrosion, loose connectors, or bro-

ken insulation at any connecting point rob the starting system of electrical

power and cause it to over-crank.

troubleshootingBefore beginning to troubleshoot the starting system, ensure the batteries are prop-

erly maintained and charged to at least 75% of their rated capacity. A drained battery

will cause any further diagnostic tests to be inaccurate. Common causes of starting

system malfunction include:

1. A battery that is low, poorly charged, or defective places high demands on

the starting system; voltage at the battery should be 12.4 volts or greater to

crank the engine. If the batteries aren’t adequately charging, a problem in

the charging system. Refer to the Alternator section of this Service Manual

for information on the charging system.

731

L


2. A starter motor can be damaged by heat that is generated by excessive

cranking. The starter should never be engaged for more than 30 seconds. It

must “rest” (cool off) a minimum of 2 minutes between starting attempts.

3. Loose, dirty, or corroded connections in the starting system rob the system

of the power needed to turn the engine. The case of the starter motor is the

ground or “return” connection for the starter motor and solenoid.

4. A loose starter motor will allow vibration that can damage the motor. In ad-

dition, the ring gear could be damaged.

5. Improper or excessive use of starting fluid will cause extra stress on the start-

ing system.

6. A defective solenoid will fail to engage the starter motor. A failed pull-up coil

will cause the plunger to fail to pull in. A failed hold-in coil may cause the

starter to fail to stay engaged, or may fail to switch the starter motor on. If

the solinoid is suspect, test the wiring of the solenoid circuit before replacing

the solenoid.

The starting circuit is among those incorporated into the Vision’s Multiplex System.

Therefore, Multiplex diagnostics procedure can help to quickly isolate the root cause

of most starting problems, and thereby minimize downtime. Refer to the Multiplex

chapter for full details on performing Multiplex diagnostics.

1. Refer to the Multiplex Output Table to find out which Port/Pin (B3-07) and

which Output LED (B3-O02) pertain to the Starter Signal Output. The chart

also shows which Ladder Logic Line (#20) describes the logic of the circuit.

2. Use the Diagnostic Switch to cycle the MPX Module to the appropriate Diag-

nostic Mode (Showing B3 Outputs). Check the LED to see if the Starter Signal

Output (B3-O03) is Active. If the Output LED is Inactive, refer to Ladder Logic

line #20 to systematically verify that each requirement for an Active Output

is true.

3. Once the Output is Active, if the starter is still not operating, verify a ground

at Pin B3-07 on the MPX Module. If the ground output is present, the problem

exists “downstream” of the Multiplex system, and the starter itself is suspect.

732

L


Ignition/Run Test

Begin by determining whether the problem is with the ignition

switch or the pilot relay, and their associated wiring; or if it is in

the solenoid and/or starting motor. To begin with the ignition

switch:

1. Connect the positive lead of a VOM to the ignition switch

terminal on the solenoid.

2. Connect the negative lead of the VOM to the chassis

ground.

3. While attempting to crank the engine, record the voltage

displayed on the VOM. Observe the following:

• No voltage

• Low voltage

• Normal voltage with slow cranking

• Normal voltage with no cranking at all.

4. Connect a remote start switch to the positive battery post.

5. Connect the other end of the remote start switch to the ignition post of the

solenoid.

6. Attempt to crank the engine with the remote switch. Record the voltage dis-

played on the VOM. If there is less than 1 volt difference from the previous

reading, the ignition switch is okay. If there is more than 1 volt difference, the

switch is defective.

7. With the VOM negative lead connected to the chassis ground, move through

the switch system one connection at a time. If your first voltage test has re-

vealed low voltage, the starter motor may be shorted.

8. If the first voltage test indicated normal voltage, but there is slow cranking or

no cranking at all, a problem with the batteries, battery cables, or a damaged

starter motor is indicated.

Low Voltage Test

There are various reasons for low voltage but the troubleshooting meth-

ods are the same. If the solenoid clicks, it means that either current is

flowing through the solenoid contacts but not through the main con-

tacts; or that the current through the main contacts is insufficient due

to low batteries.

1. Connect the positive lead of the VOM to the starter motor terminal

of the solenoid.

2. Connect the negative lead of the VOM to the chassis ground.

3. While attempting to crank the engine, if there is no voltage dis-

played on the VOM, the main contacts are not functioning properly.

4. If there is voltage present at the solenoid terminal during Step 3, the prob-

lem is in the starter motor or its cabling.

5. If the first voltage check in Step 3 under Ignition/Run Test indicated nor-

mal voltage but slow or no cranking, the next step is to check the starter

motor and its connections.

6. If the drive pinion jumps out of mesh with the flywheel ring gear, check

for a broken or loose ground wire at the solenoid.

7. While attempting to crank the engine, place an ammeter on the positive

battery cable. If the power drain is higher than the OEM specifications,

the starter motor is defective. An exception would be if the engine was

not properly tuned or is difficult to turn over; in which case, a new starter

motor would be a temporary fix.

Slow Cranking

Sluggish cranking can be caused by a small amount of extra re-

sistance in the cranking circuit. This extra resistance can come

from loose or dirty (corroded) connections, or broken wires

and/or cables. First check the positive cables and connections

of the starter motor, then the negative circuit.

1. Connect the positive lead of a VOM to the positive battery

terminal.

2. Position an ammeter between the solenoid and the posi-

tive terminal of the solenoid.

3. Connect the negative lead of the VOM to the positive ter-

minal of the solenoid.

4. Connect the negative lead of the VOM to the negative

battery post. This is the “unloaded” voltage. Record the

reading; leave the VOM connected.

5. Connect one lead of a carbon pile tester to chassis ground.

6. Connect the other lead from the carbon pile tester to the positive terminal of

the solenoid.

7. Adjust the carbon pile tester until the ammeter on the tester reads 500

amps.

8. Record the voltage display on the VOM; it should not be less than 0.4-volts

less than the unloaded value.

9. Turn the carbon pile tester to the “OFF” position.

10. Connect the positive lead of the VOM to chassis ground.

11. Connect the negative lead of the VOM to the negative battery post. Record

the reading; leave the VOM connected.

12. Position the ammeter in on the negative battery cable.

13. Turn on the carbon pile tester and adjust it to read 500 amps.

14. Record the voltage on the VOM; it should not drop more than 0.4-volts from

the unloaded reading.

15. Turn the carbon pile tester to the OFF position.

16. If the voltage drop was more than 0.4-volts in step 8, the positive cabling is

defective. Look for a broken cable or a loose or corroded connection.

17. If the voltage drop in step 14 is more than 0.4 volts, look for a problem in the

negative cabling; look for broken or defective cables, and loose or corroded

connections.

Final check at solenoid terminals.

1. Disconnect the carbon pile tester.

2. Disconnect the VOM.

3. Remove the ammeter.

4. Connect the positive lead of the VOM to the positive (bat-

tery) terminal of the solenoid.

5. Set the VOM so that it can read the full battery volt-age; at

least 14 volts.

6. Connect the negative VOM lead to the starter motor ter-

minal of the solenoid.

7. Crank the engine and record the voltage while cranking. There should be no

more than 0.2 volts drop between the solenoid contacts while cranking.

8. The voltage reading in these last three tests (the positive cable check, the

negative cable check and the solenoid test), should not total more than 1.0

volts. If the voltage drop is more than allowable, repeat the cable tests using

a jumper cable. If the tests then indicate an acceptable drop, the cable(s) is

(are) defective.

Power Distribution Unit layoutThe PDU houses the Main Bus Controller of the Multiplex system

(MPX Module), chassis fuses, relays and interface connections to

some of the main chassis harnesses. The diagram shown here is

representative of standard equipment Visions with air or hydraulic

brakes. Although some differences occur in the cases of specific

equipment options (such as circuit breakers in lieu of fuses, ex-

haust brake, or manual transmission), the general layout of the

PDU components is the same.
