Accessory Relay
- Remove accessory relay from central junction box. Central junction box is located behind left side of instrument panel. Check accessory relay continuity. Continuity should exist between accessory relay terminals No. 1 and 2, and between terminals No. 3 and 4. See Fig 1
. Continuity should not exist between accessory relay terminals No. 3 and 5. If continuity is as specified, go to next step. If continuity is not as specified, replace accessory relay.
- Using a jumper wire, apply battery voltage to accessory relay terminal No. 1. Using a second jumper wire, ground accessory relay terminal No. 2. Continuity should now exist between accessory relay terminals No. 3 and 5. If continuity is not as specified, replace accessory relay. If continuity is as specified, accessory relay is okay at this time.
