Circuit Test: M/T
- Turn ignition switch to START position and check for near battery voltage at starter solenoid terminal No. 50 (Red/Yellow wire). If near battery voltage exists and starter does not crank, repair or replace starter. If voltage does not exist, check for voltage at terminal No. 3 (Red/Yellow wire) of interlock relay with clutch pedal fully pressed to floor. See Fig 1

- When clutch pedal is depressed, clutch switch grounds interlock relay terminal No. 1 (Green/Yellow wire), which energizes interlock relay. Interlock relay has a Blue 4-terminal connector and is located on brake pedal bracket, next to brakelight switch. Clutch switch is located at top of clutch pedal arm.
- If voltage exists at relay terminal No. 3 (Red/Yellow wire), repair wiring between relay and starter. If voltage does not exist, check for near battery voltage at interlock relay terminals No. 2 and 4 (Blue/Red wires) when ignition switch is turned to START position. See Fig 1
. If voltage exists at relay terminals No. 2 and 4, go to step 5).
- If voltage does not exist at relay terminals No. 2 and 4, check for voltage to ignition switch BAT terminal and from ignition switch START terminal. Repair wiring or replace switch as required. If voltage exists at START terminal, repair Blue/Red wiring between ignition switch and relay terminals No. 2 and 4.
- If voltage exists at relay terminals No. 2 and 4, ground interlock relay terminal No. 1 (Green/Yellow wire) using jumper wire. Check for near battery voltage at relay terminal No. 3 (Red/Yellow wire). If voltage exists, replace clutch switch. If voltage does not exist, replace relay.
