TR6 Horn Assembly Question 74 TR6

[benjaminabby04]

I am getting around to test a few theories on my horn which does not work.

I have tested the horn directly by wiring direct to the battery - she blows.
I have hopped a wire from my ground to the relay - she blows.
I have removed the horn assembly from the steering column and have taken the horn wire and connected to a ground - and she blows.

I have taken the assembly apart - ensured that the brass connection ( round brass disk- with a coiled wire) is touching the brass connection contact ( small round 5mm ) by compressing the shield so that all connect expecting it to blow - she did not.

I touched the connection pin on the back of the assembly piece( while the horn wire was connected to it) to the inner steering column ring ( hoping to ground) - she did not blow.

I know that the horn works by grounding - what am I doing wrong and what is the fix?

thanks ever so much

Might check and see if the spring loaded contact isn't broken. the flex-wire inside the clear plastic tube often breaks. Just make sure you order the correct length by measuring.

I am only familiar with TR4s, not TR6s, but form your description they may have a similar horn button arrangement.

On a TR4 the completion of the circuit depends on the steering column being grounded. Because a 4's column has a couple of rubber donuts there are 3 ground wires involved... one at each donut and one at the base of the column. If any are missing or broken the hub of the steering wheel is no longer a ground and the horn does not work.

The grounds are made with flexible braided wires though in a pinch a regular wire with ring terminals at each end could probably work.

A couple of quick tests with an ohm meter followed by a visual inspection may find the problem.
