scott.wild Posted July 17, 2017 Share Posted July 17, 2017 Double check the horn grounding point, run a temporary wire back to the battery ground. Quote Link to comment Share on other sites More sharing options...

I'll try look for the battery ground now Where is your horn button earthing? At the moment just a earthing point just on the inside of the engine bay next to the fender , where the original earth wire went Quote Link to comment Share on other sites More sharing options...

Is the horn intermittent? Quote Link to comment Share on other sites More sharing options...
Lewmc93 Posted July 17, 2017 Author Share Posted July 17, 2017 I'm not even up to that part yet , I've just wired it up over the car for now to check it was working but it's not, the horn is none exsistant when done through the relay , I tried the old relay still not working Quote Link to comment Share on other sites More sharing options...

Move it about and see if the horn starts working Quote Link to comment Share on other sites More sharing options...
Lewmc93 Posted July 17, 2017 Author Share Posted July 17, 2017 I don't have a stock wheel and boss mate , So no clock spring and original wires are used , I've just wired it up over the car for now to check it was working but it's not, the horn is none exsistant when done through the relay , I tried the old relay still not working What does work so far is .... Battery - 10amp fuse - steering wheel horn connection 1, steering wheel horn connection 2 - horn - ground So no relay, Do I really need one if it's done this way?

Why are you running the aftermarket relay? Quote Link to comment Share on other sites More sharing options...
Lewmc93 Posted July 18, 2017 Author Share Posted July 18, 2017 Because the original one was shot , rusted and knackered so for £3 I just replaced it with a new one, Had a look this morning I think the original live wire to the horn is broke somewhere.

Al Massey Posted July 18, 2017 Share Posted July 18, 2017 Do you not have a multimeter? If not buy one, they are not expensive and you can do a continuity check on wires Quote Link to comment Share on other sites More sharing options...
