Horn Push brush/wiring
Posted: Mon Sep 13, 2010 8:30 am
Hello
I went to the Beaulieu Autojumble on Saturday and trawled the 2000+ stalls looking for a horn push to go on my new TTR steering wheel. I found one, in black, and very pleased to get it for ?25. It was not perfect condition, but very respectable and at the price I couldn't refuse. It was only when fitting it I realised I'm missing the connection between the brass terminal on the back of the horn push and the brass ring on the steering column.
I fashioned one from a spring loaded brass rod that came with the old aftermarket steering wheel and some brake pipe but it was making a permanent connection. I also noticed that the steering wheel itself was closing the circuit by touching the brass ring, I insulated the back of the steering wheel to prevent this.
Can anyone tell me what should be in place for this connection? I could only find one small reference to it in all of my manuals and it was referred to as a 'horn brush'. Also if I can either buy one new as I don't have time to hunt around for one or make one up quite easily, i.e. if anyone else has a home made one that works. The main problem seems to be insulating the connection so it doesn't touch the steering wheel before it gets to the horn push terminal.
The good news is I got the multimeter out and tested the button and the other connections and everything is working, got 11.95V at the compressor which is working now. What a great noise those air horns make!
