Re: {Chrysler 300} '55 300 coil wiring question

Hi Jim,   
The correct polarity for the coil is to connect the + wire from the coil to the distributor.  The theory is that the HOT electrodes in the spark plugs will spark just a little bit more easily if they are charged with a negative charge (surplus electrons) because in that way they act just a little as an electron emitter.  The reality is that the difference is so slight it's likely negligible in practice.

Hello all,

 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.

Thanks,

Jim
