Accessory Relay: Testing and Inspection

ACCESSORY RELAY INSPECTION

1. Remove the accessory relay.

2. Inspect for continuity between the accessory relay terminals using an ohmmeter.





Inspection (no voltage applied)





Component testing procedure (voltage applied)Disconnect the ohmmeter; connect pins 30 and 85 to 12V DC power and pin 86 to ground. Measure voltage between pin 87 and pin 86. If the voltage is 12V, continue with the test. If not, replace the relay. Disconnect power from pin 85 and measure voltage between pin 87a and pin 86. If the voltage is 12V, the relay is OK. If not, replace the relay.

1. If not as specified, replace the accessory relay.
