Introduction

This special instruction contains general information and procedures in order to perform the inspection

of the backup switch. Even if there are symptoms of a short circuit or intermittent contact on the toggle

switch, in most cases the function of the toggle switch is normal. Refer to the inspection procedure

below. This will help to identify the root cause of the problem before you replace the toggle switch.




3/11

Refer to the Service Manual Module of Systems Operation, Troubleshooting, Testing and Adjusting,

"Machine Electronic Control System" for the adaptable model.

Inspection Procedure

1. Check if the machine moves when the toggle switch malfunctions. Refer to the explanations on

Backup System of Service Manual Module of Systems Operation, Troubleshooting, Testing andAdjusting, "Machine Electronic Control System" for the adaptable model.

2. Check if there are any loose screws on the terminal connection of the toggle switch. If there are

any loose screws, tighten to a torque of 0.6 0.1 Nm (0.44 0.07 lb ft). Refer to Illustration 1.

3. Conduct the electrical continuity test between each terminal before replacing the toggle switch.

Refer to Illustration 1. If a short circuit or intermittent contact between the toggle switch

connection and the harness terminal is found, identify which harness terminal contacts the switch

terminal. Refer to Illustration 2 through Illustration 9.

4. Cut the peripheral of the ring terminal with a nipper in order to avoid the terminal contact with the

body of the switch. Refer to Illustration 10 and 11. The short circuit or intermittent contact is mostlikely to happen when the harness terminal is connected with central connections of number 5 and

number 8 switch terminals. Refer to Illustration 2 and 3. If the problem will never be resolved,

replace the former harness assembly with the new harness assembly of the latest version for

Series D excavators and 365C L and 385C excavators that are listed. A yellow tape was placed on

the number 8 terminal of the toggle switch in order to prevent the wrong harness connection for

the machines with the 259-4877 Console Harness As or the 251-0601 Console Harness As of the

latest version that was implemented. It is possible to identify if the machine has the new harness

assembly or not based on the existence of the yellow tape on the toggle switch of the machine.

Refer to Illustration 4 and 5.

The harness terminal assembly from number 1 to number 12 is connected with the corresponding

terminal of 283-3074 Toggle Switch . The 128-4189 Terminal As was adopted for the terminals from

number 1 to number 12 except number 7 and number 10. Refer to Table 2.
