Electrical issues

Maybe check the voltages at the coil when it is idling...alternator connected, disconnected and put the meter on AC and see how many millivolts  of AC you get across the battery stud on the alternator and the case of the alternator.

Sounds to me as if something went awry when you installed the new ignition

When I got the car it had 2 ballast resistors so I installed one of the 4 way resistors and wired it per the wiring diagram. The coil has not been replaced either.  Going to run a few tests and see what the results are.

Also, the choke is powered off the ballast resistor. I know it's better to run that of the fuse block. I will disconnect that and see if it makes a difference.

it is normally bad to do that..unplug it and see

Thanks to everyone. My problems appear to be solved. I cleaned up the grounds With fresh bolts and lock washers and that seemed to have taken care of the problems. I'll know for sure once I get a chance to take it for a long drive at night.
