- Remove solenoid relay, located on top of actuator. Using a DVOM, check continuity between specified relay terminals. See Fig 1. Continuity should exist between relay terminals No. 1 and 6. Continuity should exist between relay terminals No. 3 and 5. Continuity should not exist between relay terminals No. 2 and 5.
- Using an ohmmeter capable of testing diodes, check for continuity between terminals No. 4 and 5. Transpose ohmmeter leads. Check for continuity again. If continuity exists for only one measurement, solenoid diode is okay. If continuity exists for both measurements, diode is shorted. Replace solenoid relay.
- Connect fused jumper wire between positive battery terminal and relay terminal No. 1. Connect another jumper wire between negative battery terminal and relay terminal No. 6. Continuity should exist between relay terminals No. 2 and 5. Continuity should not exist between relay terminals No. 3 and 5. If continuity is not as specified, replace solenoid relay.
