No power to ignition coil, Please help

[jaxs]

Most 12v auto/truck coils before mid 70s will work. Just be sure it's internally resisted or use resistor for same application as coil. New condensers are junk so if you still have old one,switch it in if problems persist. Look for these brands of condensers,Blue Streak,Standard Motors or Echlin. Napa can order if they don't have on hand. There's a spark tester available for $3-$5 (clear plastic bulb with 3" of plug wire attached) that install's between plug wire and spark plug. Easy to see spark and free's up hands not having to hold plug wire while looking for spark,,,,,,and getting shocked.:laughing:

To follow up and end this thread, I fixed my issues. The original and second coil I purchased were both indeed bad. After I fixed the electrical/broken wire, I was able to maintain 12v to the + side of the coil. I then replaced it with a pertronix 40611 epoxy filled 3.0 ohm coil. It fired right up. Since then I replaced the distributor cap, all spark wiring, and I installed the pertronix EI. It started up but stumbled around until I loosened the distributor and rotated it to find a better idling and running RPM. I still need some guidance on fine tuning the ignition timing via the distributor. Thank you all for the help.

That's good news. Check with auto parts stores about borrowing a timing light. Thanks for the up-date.
