1950 MM Horn Ground on Steering Column Problem
Posted: Tue May 10, 2022 1:53 am
I own a 1950 US export model Tourer. One of my winter projects was to refurbish the wiper motor, wheel boxes, and wiper rack. In removing and replacing the wiper parts some bullet connectors became separated. All that is resolved, but there is now a problem with the horn. I assumed that too was due to a loose bullet connector, but it turned out to be a dirty fuse holder under the bonnet. The horn worked fine when I put the car away for the winter.
As part of trouble shooting, I removed the horn ground pieces from the steering column support bracket. I knew these parts were a problem from previous experience, and the insulator is squashed flat and rather useless. When I reassembled the ground pieces, the horn blew continually. No amount for reordering the parts, or substituting rubber washers or grommets for the worn insulator made a difference.
The only information I have found regarding these parts is on plate D in the Morris Minor Service Parts list. Attached are photos from the parts list and from my car.
I replaced the parts in the order shown in the diagram, and tried placing the wiring harness connector in several different locations. The diameter of the connector is huge, and I also tried a size that is just large enough to fit over the bolt. Nothing makes a difference and the horn blows continually.
What is the correct order of parts, including the wiring harness connector?
Are replacements for any of these parts available? If not, what do people substitute for the originals?
Thank you,
