The '55 Windsor factory diagram available online for the 6 volt positive ground system shows the + wire from the coil going to the distributor. My handy-dandy $25 color wiring diagram from ClassicCarWiring.com shows the - lead of the coil going to the distributor.
And unfortunately, there isn't a diagram in the shop manual. I could check other diagrams, but they are for 12 volt negative ground, I don't know if that makes a difference with
coil wiring.
I'm more inclined to believe the factory diagram, but can anyone tell me which is correct? I would not believe how my car is wired knowing the idiots that owned it before me.
