Horn Mystery

[nicholascummins]

I'm having trouble working out where the wires connect to this horn on my 57 88inch. I cant get the metal dome off,cant find any screws that hold it on except what I think is the tone adjuster screw which isn't holding the dome on. I asume I conect the wires inside some how. baffled.This also could be a non original horn. any help would be great. Nick

Nick - If what you call the tone adjuster screws into a blind hole (rather than through a nut) then it may well be your positive terminal (with negative being earth through your mounting). drew
