Re: Coil wiring diagram /1954 pacific/cruising rpm engine bogging/coils

Aloha Howard. So this is what we have. The end is near. 1954 Packard Pacific with 359 L8 and GM 700R4 trans. The car cranked but wouldn't start. Car has auxiliary electric fuel pump. Turns out the engine was flooded. Screw driver, ether and pedal to floor. Problem solved. But, in process I changed coil, plugs and rotor. And mistakenly reversed the coil polarity. Stock 1954 wiring for coil has 2 wires. Ignition wire to Neg. terminal and Distributor wire to Pos. terminal. My car when arrived had a ground wire to the coil bracket from Pos. terminal and both the ignition wire and distributor wire attached to the Neg. terminal.
Net :"A coil with reversed polarity will have about a twenty percent lower output which may not show up at idle and low rpms, but can cause an engine to miss or stumble under load and at higher engine cruising rpms."
Once the polarity was sorted out I bogarted multiple after-market coils all with different primary and secondary resistances. Turns our the original one was ok as well. I added a new Pertronix Flamethrower #40011 coil and ordered a Brillman Stinger (OCD). Turns out the distributor has another orange wire coming out of it!! The car has a tachometer but it also has a Pertronix 1188K ignitor!! I wasn't sure until I took the cap off and got in there. Hence your suggestions were correct and due to the ignitor will keep the wires where they are. Again, the bogging seems to be gone. Not sure what would happen if I put the distributor wire back onto the Pos. terminal though.From picture, my rotor isn't in No.1 spot, thoughts? Thanks again.
