Triumph TR6 - No horn...

Hello chaps

I am finally getting the TR6 ready for inspection here in Texas, and find that I don't have a working horn. I installed a new Moto Lita steering wheel last year and can't remember testing the horn after I installed it - pretty stupid, right?

I don't think that the steering wheel is the fault, though, as the purple fuse blows whenever I press the horn button. I hear the click of a relay and then the fuse blows. This is probably pretty simple stuff, but electricity is a total mystery to me. Any thoughts appreciated.

Cheers

My horns don't have a relay but the power goes from the fuse to the horn to the horn button. When the button is pressed it completes the circuit and- voila -noise.
Your horns may be improperly grounded or short circuited.

Alistair... the Dan Masters Book covers this subject very nicely if you have access to one. For now from memory I'd suggest you have a dead short. When you press the horn button and it in turn it presses the horn push against the brass ring the circuit is closed without getting through the horns to ground.

Down at the horns check their ground wires to make sure their terminals and connection points are super clean.

Follow the purple wires and their respective black ground wires to ensure they are not bare somewhere and touching something metal. The horn relay (the one with the purple wires) clicking must mean you do not have a problem with the steering wheel and horn push. I just made the same switch over to Moto Lita last summer.

Let me know if you need something from the book scanned and emailed to you.

Sorry Michael... your posting was not there when I read Alistair's note.
