Re: Engine Wiring with Pertronix electonic Distributor
Not exactly the same, but I am installing a Pertronix system on my 327 in my 69 Chavy C-20 truck and this is what I learned.
On the truck I was told to take the yellow wire off the coil and the solenoid. Tape them off and leave them there in case you want to go back to points.
The yellow wire on the coil is also connected to a cloth covered wire that goes to the bulkhead connector.
When cranking the starter, the yellow wire from the starter provide a full 12V to the coil to help start. When the truck is running and started is disengaged, the wire to the coil goes through the cloth covered wire which is a resistance wire and drops voltage to 6V thus saving the coil.
When you switch to Petronix or HEI it needs full 12V all the time.
So you need to get a wire from ign to coil that is full 12 volts and that is all you need.
There are two ways to do this.
Pull out the cloth covered wire from the bulkhead (packard style 56 balde connector) and replace it with a 12G wire to the + side of coil.
Or just run a new 12G wire to ign unfused to positive side of coil. This is what I am doing so I can easily put points back in if I need/want to.
If there is a ballast resister (white block) it can be removed.
Hope this helps.
