need help with wiring


Recommended Posts

The horn is normally powered, needeing only an earth on the return line to make it work. If the radio was connected to the return wire and was of low power, it might just be that there is no power coming back from the horn, because the horn has failed and is not a closed circuit. Please clean connector and horn terminals to get good connections. Fill connections with baking soda and drip water to dampen it-leave several hours. Rinse clean, rinse again with methylated spirits and let dry 8 hrs. you should be able to see BRIGHT metal in both connectors-clean/scratch until you can. {no glasspaper or nailboard} Reconnect & test horn, whilst moving connections on horn. Please test the wiring at the horn for 12V+ on both sides with the connector & ign on and the horn off. A test light or voltmeter will do. If power is available both sides, please ignore what I just wrote. If no power either side-check fuse. If power one side, horn is u/s-REPLACE!!!!
