Chrysler Electronic Ignition No Spark

1...Make absolutely certain the ECU is grounded
2...Check voltage at coil + to ground with key in "run." Should be "down" around 6-10V with a fully charged battery at 12.X
3...Check above again while cranking WITH THE KEY. Should be 'same as battery' and no lower than 10V, and better, higherV.
4....With key in run, and coil wire held near engine, or connected to test gap, disconnect dist. harness, and take the engine bay side of the connector. Tap the bare terminal of the 2 wire connector to ground. Should get a nice hot "snap" spark each time

1: If I understand correctly the box should ground itself to the body through the mounting bolts. Both are good grounds and I checked them with my test light.

2: I don’t have a volt meter to be 100% sure but at both the resistor and the coil positive the light on my test light is noticeably dimmer

3: again can’t really check ATM but I got a buddy with a meter coming by later.

4: which end of the coil wire? Does it still need to be hooked up to the coil or dist?
