Running I have 11 volts on the input to the coil and 8.2V on the distributor terminal of the coil with the alternator charging at 14.4 volts. Reading comments on this forum directed at 6v systems, I see 4v is recommended. I've Googled a good bit and can't find any info on voltage to the points. I'm looking for help to determine if I need more resistance, or if I just have crappy points. The ones in the distributor are Delco. Thanks for your guidance.
Maybe a capacitor issue? You should have plenty of resistance with a 1.5 ohm coil and 1.8 ballast resistor! Are you sure on the coil resistance? Did you measure it?
