Section III. WIRING HARNESSES

TM 5-3835-222-BD

Procedural Steps:

Option 1: Bypass starter switch.

a. Locate the starter switch.

b. Remove the wire from the starter switch.

c. Use a jumper wire or touch the wires, removed in step b, together.

d. After engine starts, disconnect jumper or leads.

e. Insulate lead with tape.

Option 2: Jump starter terminals.

a. Gain access to engine starter.

b. Using a piece of wire or suitable object, connect the main power terminal to the solenoid terminal.

c. After engine starts, disconnect jumper.

Record the BDAR action taken. When the mission is completed, as soon as practicable, repairthe

equipment using standard maintenance procedures.

Damage to the equipment can occur when the circuits are not properly fused.

7-7. Fuse or Circuit Breaker Failure. A short or overload in a circuit will cause the fuse to burn out

or the circuit breaker to trip. The circuit becomes inoperative. A temporary repair can be made by

bypassing the protection device with straight wiring, or by replacing the fuse with tinfoil, wire,

ballpoint pen spring, or similar conductor. Use of solder will provide some amount of circuit protection.

Section III. WIRING HARNESSES

7-8. General. Wiring harnesses are normally replaced when extensive damage occurs. Because of

improvements or different configurations, replacement harnesses from other POL equipment of the

same family may use some different style connectors. Try to obtain harnesses from an identical

model; however, connectors can be exchanged with the damaged harness. The same procedure

is followed to change a complete connector or splice a completed harness. If a wire is damaged

but the fault cannot be located, it should be replaced with a jumper wire.

7-9. Wiring Harness Damage. Wire harness repairs are generally a series of single wire repairs.

Establishing circuit continuity in a bundle of wires is difficult because individual wires are not color

coded. Wires must be identified before they are connected. Most essential electrical functions can

be rapidly restored by using jumper wires. An alphanumeric code is imprinted onto the outer insulating

jacket of each wire. A point to point run of each wire can be determined from the troubleshooting

diagram plate and the alphanumeric code.
