I've been having a hot start problem somewhere in my ignition, no spark when the car is hot but let it sit for 10 to 15 minutes and it fires right up. I have 11.7 volts at the coil (with no load when hot) and assumed it was the module in the msd distributor. Got the distributor rebuilt and the problem did not go away. A friend of mine installed a resitor several years ago (when converting to hei) claiming I need it to prevent the ignition switch from burning up. Anyway, do I need this resistor? Also, with the points system there was an extra wire (maybe two) that went down to the starter, I just taped those wires off and did not use them with my new starter, could this be where my problem is?
