Horn Relay: Testing and Inspection

1. Remove horn relay.
2. Using ohmmeter, test for continuity between ground and terminal 12 of junction block.
a. When the horn switch is not depressed, no continuity.
b. Continuity to ground when horn switch is depressed.
c. If continuity is not correct repair horn switch or wiring as necessary.
3. Using voltmeter, test voltage at:
a. Terminal 11 and 13 test for battery voltage from fuse F30.
b. If voltage is incorrect repair as necessary.
4. Insert a jumper wire between terminals 13 and 15 of the junction block.
a. If horns sound replace relay.
b. If the horns do not sound, install horn relay and refer to Horn Diagnosis and Testing.
