  1. Turn ignition switch to START position, press clutch pedal to floor and check for near battery voltage at starter solenoid "S" terminal (Black/Red wire). If near battery voltage exists and starter does not crank, repair or replace starter. If voltage does not exist, check for voltage at interlock relay terminal No. 3 (Black/Red wire). See Figure.
  2. Interlock relay has a Blue 4-terminal connector and is located behind center console, above radio. When clutch pedal is pressed to floor, clutch switch grounds interlock relay terminal No. 1 (Green/Yellow wire), which energizes interlock relay. Clutch switch is located at top of clutch pedal arm.
  3. If voltage exists at interlock relay terminal No. 3 (Black/Red wire), repair wiring to starter. If voltage does not exist, check for near battery voltage at interlock relay terminals No. 2 and 4 (Black/White wires) when ignition switch is turned to START position. See Figure. If voltage exists at relay terminals No. 2 and 4, go to step 5).
  4. 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 Black/White wiring between ignition switch and interlock relay terminals No. 2 and 4.
  5. 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 (Black/Red wire). If voltage exists, replace clutch switch. If voltage does not exist, replace relay.

  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
