Headlight Relay

Remove headlight relay (located in relay block No. 1, on right side of engine compartment, behind shock tower). Using an ohmmeter, check continuity between relay terminals. Continuity should exist between terminals No. 1 and 2. See Fig 1. Apply battery voltage and ground between terminals No. 1 and 2. Continuity should exist between terminals No. 3 and 4. If continuity is not as specified, replace headlight relay and retest system operation.
