And I guess these electronic ignitions do not have condensers.

Okay lemme go test the plug the way you said.

No condenser. Measure the gap between the black round piece and the little rectangular black box. Needs to be .030

TAKE OFF NEGATIVE BATTERY CABLE.....Measure the gap between the black round piece and the little rectangular black box. Needs to be .030. I'll stay with you at my computer. Tell me when you get tired and I will go eat dinner. Better faster to use email at this point. If you wish, PM your email address.

Never really looked closely at these before. .030 does fit but a bit tight feels more like the .028 slid better. But does go.

Close enough. Check all the wires and their terminations. Then one final test before declaring the unit dead. I will post that in a minute.

From the Pertronix the red wire goes to the coil positive and the black wire goes to the coil negative they look solid. The positive on the coil also has the yellow and black wire that comes from the firewall.
