Quote: OP make sure your source provides 12 volts to the petronix unit when hot. I had a car that ran well for a time, 30 minutes or so, then once things were good and heat soaked it died. When hot my source had less than 12 volts. Was fine cold.
I let the car sit overnight, tried it the next day, and still no spark. Should a volt tester on the + side of the coil give me voltage? Man I'm not good with this electrical stuff......
