Lucas 9H Horn Repair
Posted: Thu Mar 14, 2024 1:19 pm
My Lucas 9H horn is not working properly and I have had to temporarily fit a modern replacement. It does not sound the same so I do not like the modern one.
I have watched a few videos on Youtube showing repairs on the 9H. It is very simple inside, a set of points, a coil and a diaphragm. It's basically like a speaker except for the points. Providing the coil is intact, it seems the most common fault is dirty points. Unfortunately, the unit was not meant for disassembly and the rivets have to be drilled out to get inside. It can of course be riveted back together with pop rivets.
I just wondered if anybody on here had repaired a 9H and how they got on with it? Was it a long term fix or did the horn fail again after a short time.
