Horn malfunction

Post by Richard Watts » Tue Nov 17, 2020 4:21 pm

1964 MGB ROADSTER (5-bearing):
Horns sound only after several presses in various places on horn-push, whether ignition is on or off.
Original horn-push dismantled and refurbished twice.
New wiring loom at 1993 rebuild.
One horn original, one horn replaced: both working.
All connectors checked and cleaned.
SUGGESTIONS PLEASE.

Richard, this sounds as if you have checked most things!
My experience is based on my '72 so I am assuming your earlier car is similar.
Have you removed the covers over the top of the steering column whilst removing the horn push?
Underneath there is the grounding mechanism for the horn push. I suspect you may have an issue with electrical continuity somewhere in there.
With the mechanism exposed you should be able to easily complete the circuit and in this way determine if the horns themselves are functioning reliably. I have had to make some minor mods in that area to get a reliable contact in my car.
