Start over - ! Ha! Just wish is would start right!
73 Duster w electronic ignition.
I Disconnected starter wire from relay so it wouldn’t crank.
I put a test light on Ign2 when key on and it is half brightness.
Turn the key to start and it goes full brightness. OK
I put the light on Ign1 side of ballast and is full brightnes in run and dims when switch is turned to start.
Turning it back to run and pull Ign2 wire from ballast. Ign1 Still at full brightness. But when I turn the key to start, the light goes out.
So, when the Ign2 is connected, and turned to start, the Ign1 side is seeing voltage dropped the other way thru the ballast and the ECU being powered from that side is only seeing half voltage.
I hope this clarifies the problem. Today I’m going to jump 12v to the run side and see what happens.
*As soon as the wife gets up. Open headers. Don’t need/want to wake her up.
but looking at some diagrams I’ve found of the switch, I cannot tell if the ign switch is functioning properly.
I would think the ECU would need a full 12v.
