I have a 1975 mercruiser 4 cylinder. I have the pertronics igniter II (91146a) and flamethrower II coil (45111) that I will be installing this week. I need help with wiring. My current coil has two wires coming to the + lead. Both are tannish brown and both disappear into a taped up bundle, so it is hard to trace where they are coming from. I'm assuming that one may be a resistor wire, which I don't need anymore because I want a full 12v coming to the new coil. The customer support guy at pertronics said to just unhook and tape off the resistor wire to get full voltage to the coil. How can I figure out which wire is the resistor wire? I'm not good with wiring, I'm sure this is very simple to many people, and many people have to work around a resistor wire in this situation.
Any simplified suggestions would help. I'm thinking that if I just unhook one of the wires to the positive lead and see what I get for voltage, and then try the other one and see what I get for voltage, I might get my answer? If one of them gets me 12v and the motor turns over, and the other gets me nothing, then just unhook and tape off the one that gets me nothing?
Sorry. There is a lot on this topic, but I have been struggling to understand all of it.
