So i decided to work on my Horn (As it never worked since purchase). I found out that a bunch of parts were missing and the incorrect horn contact plate was used.

I called up Mick Motors and ordered a part (I described my situation and the blinker set up).

This is what i got up to. and there is no grounding on the body with that provided wire from the new plate. (Sparks and such).

Did this resolve the horn issue? It isn't clear in your thread above.
Great photos, very descriptive and helpful.
