my GTV has just failed the MOT because the horn does not work.
Strangely it only works when the key is out of the ignition.
Anyway after a bit of diagnosing with a multimeter it appears the fault is down to a bad ground connection to the centre of the steering wheel ( return path for horn contact ).
I need to get hold of a puller to get the steering wheel off in order to do some further investigation.
In the meantime does anyone know if the centre earth for the steering wheel passes through the clock spring device or whether it just relies on the steering linkage.
