I was messing around with my ignition wiring, & now I don't remember how the wiring from the ignition switch to ignitor to coil is suppose to be. Can anybody help ?? Also, I'm looking at replacing my altenator wiring. What gauge wiring should I use ??? Thanks in advance, Timo.

I'll take a try:
You need a switched source to the Pertronix unit that is on only when the ignition is on or in start. Pertronix recommends 12 volts for this. You can tie into the ignition switch side of the pink resistor wire.

This coil can use the exisitng 6 volt source from the pink resistor wire that comes from the ignition switch. You can find the pink wire under the dash. Hope this helps.

One wire goes to the coil and the other wire goes to a switched 12V source. On mine, I wired that one directly to the ignition switch. One of the wires on back of the switch feeds to a fat pink resistor wire via bullet connectors. I made a Y adapter out of bullet plugs to tap into this junction, then ran the new wire through the firewall grommet and along the engine harness to the Pertronix. Worked great.

Apparently, in many cases the pertonix will work fine if you just wire both wires to the coil. This has been debated on VMF. Because the coil is a 6V source, my understanding is that weak wiring in a 35 year old car can potentially cause Pertronix problems due to undervoltage.

Whisperer has an excellent site on proper wiring of a Pertronix. If he doesn't respond to your post, you may want to send him a message.

I don't have anything to add to this except that I am totally in awe of the trouble you guys go to to help others. I have been lurking around this forum for about 6 or 8 months and I have been helped in the past, also. I just want to pass out kudos (not the candy bar things) to all of you VMF'ers (very important to keep the "V" on that) that help make my day. I am proud to be a small (mostly taking, very little giving) part of this forum..

The others addressed the Pertronix pretty well ... I am one of the ones that used the ignition wire on the coil side of the resistor wire with no problems (and on 2 different cars).

For the alternator wiring, I'd suggest just buying a repro alternator harness. They are inexpensive, have all the correct ends and wire colors already, and will make it about a 30 minute job to switch out.

Thanks all for replying. I still have one wire that I'm not sure what to hook up to. I have 3 wires that are bundled together, a red one that should go to the coil, a black one that goes to a ground on the block (I think as that is what it looks like) and another black wire that goes ??? Sorry but, electrical wiring on the car is not my strong suite. Come to think of it, nothing really is.

keep the "V" in that... HA!!! I guess I never noticed the similarity in the two acronyms!
