Power Main Relay
NOTE:
Power main relay may also be referred to as PWR relay.
- Ensure ignition is off. Remove power main relay. Power main relay is located in fuse/relay box at driver's side of instrument panel. See Figure.
- Note identification of electrical terminals on power main relay. See Fig 1. Using ohmmeter, check that no continuity exists between terminals No. 3 and 5 on power main relay. Check that continuity exists between terminals No. 1 and 2 on power main relay.
- Using jumper wires, apply battery voltage and ground to terminals No. 1 and 2 on power main relay. Check that continuity now exists between terminals No. 3 and 5 on power main relay. See Fig 1. Replace power main relay if defective.
