Thanks for all the suggestions. I think I'm about to throw in the towel and go back to points. You're right the Jeep was starting and running...Where did it all go wrong? I've put new parts into this HEI and it keep failing! Next is to buy a condenser? What sucks is the new coil through a spark...Now its dead? What killed it? I did a lot of continuity testing grounds etc all night and after reading your suggestions this morning. Everything is fine but what's weird, is, I've got 12 volts to the distributor ("battery" on the HEI), I also can get continuity through the same wire to any ground on the jeep??? I traced the wire to the ignition switch, the only way to get the continuity to stop is the unplug the plug from the switch. It's the main plug that has the large red, lg purple and lg green ignition wire. Is this correct?
