Javelin Horn.

Another techn ical glitch to test your brains.
My car is off the road for some work prior to the next seasons frolicking.
Over the last couple of years of use I have had a problem with the horn sounding on full lock. I ran with it disconnected at the slip ring and just connected it for the test.
I would like to fix it...does anyonyone have any good ideas of where to find the 'short' to save going through the whole circuit ?

The feed to the horn goes into the steering column about half way down where it as attached to the slip-ring from where a wire goes up to the push button in the steering wheel. The fault is probably in the slip-ring assembly.

Putting an ohm meter between the feed into the slip-ring and earth will prove the fault when it shorts on full lock.

It is one job I also have to do, having put off changing the slip ring ever since I had the car.

Thanks for that FA. I guessed it might be in that area . I will put a battery on and have a poke round while the car is a couple of feet in the air on axle stands having its brakes done.
PS, It's just taken me 10 attempts to get into Jowett Talk each time the 'cannot display' message comes up !.

Ted, from down under, Safer to disconnect it and put in a separate horn button. Stops embarresment at corners.

Is the UK still living ??

Drummond,
Glad you and Ruby having a good time. This little bit of God's UK still alive and kicking.
Thought about a separate button, did this on a previous car but still nice to have the real thing. Other alternative is to try not to go round any corners !
Have a good trip
Regards Ted.

My car came with a separate button, though inspection showed the slip ring was in place. The short may be casued by deflection of the steering column within the outer tube. At the top of the tube is a felt washer which in my case had virtually disintegated, which allowed the steering wheel to move from side to side and up & down. I replaced this with a nylon top hat shaped sleeve, turned on a lathe, with a few thou clearance on the shaft. This removed all the steering wheel wobble and acted as a top bearing too. I then replced the horn slip ring slipper 'thing' and all is well.
