Sweet...this post highlights the hell that I have been going through for the past 2 weeks.
Car: 66 Buick GS
Problem: Ignition cuts out randomly, no specific RPM. It randomly cuts back in, throws me against the seat when power is regained. Scary. Today it won't start at all.
Ignition System: Pertronix Ignitor
First, I cleaned up the entire wiring harness and made sure all the wires had good continuity. I tried to start it up last night, but it cranks with no spark whatsoever. The coil seems to be putting out no spark at all. This morning, I brought my meter out and checked to make sure I was getting voltage to the (+) side of the coil. Well, I am getting *12V* worth with the key in the "ON" position. My car's wiring harness is unmodified, and the feed from the bulkhead to the coil is supposed to be a resistor wire. So I figure either this resistor wire is shorting against a 12V wire inside the harness, or the yellow "r" wire off the starter solenoid is permanently supplying 12V, not just while cranking. Is this even possible? Could this be indicative of a bad ignition switch rather than internal arcing inside the starter solenoid?
I am thinking that the 12V to the distributor has FUBAR'd my Pertronix module, hence the lack of ignition now.
Thanks for all your help, guys.
Larry: I believe that the voltage drop to the coil is required to prolong the life of the contact points. I suppose the heat generated from power dissapation across the contacts will oxidize/burn up the point material.
