Component Tests and General Diagnostics
1. Remove the relay.2. Using a jumper wire, connect one end to terminal 85 of the relay. Connect the other end to ground.
3. Using a second jumper wire, connect one end to terminal 86 of the relay.
4. Connect one lead of an ohmmeter to Terminal 87 of relay. Connect second lead to Terminal 30 of the relay. Observe the resistance.
5. Momentarily tap unconnected end of second jumper wire to the positive battery lead. An audible click should be heard and the resistance on the ohmmeter should drop to zero.
6. If the relay does not click or the resistance does not drop to zero, INSTALL a new relay.
