  1. Ignition OFF, disconnect the IGN MAIN relay 31.
  2. Test for 70-150 ohms of resistance between terminals 85 and 86.
    • If the resistance is not within the specified range, replace the relay.
  3. Test for infinite resistance between the following terminals:
    • 30 and 86
    • 30 and 87
    • 30 and 85
    • 85 and 87
  4. Test for less then 2 ohms of resistance between terminals 30 and 87A.
    • If greater then the specified range, replace the relay.
  5. Install a 3-amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Measure for less than 2 ohms of resistance between terminals 30 and 87.
    • If greater than 2 ohms, replace the relay.
