Finally fixed, thanks for the help guys, would just like to say most golf horns stop working because of 1 thing. But no, not mine,
Took the steering wheel rubber off and found the earth wire was not connected to the steering column, secondly I fixed the broken wire as shown in the previous post, and then I had ground at the horn and it still doesn't work. Unplugged 1 and now it works, what a nightmare of a job.
Chuffed now tho
