Alternator question

Thanks guys, sorry I wasn't able to get as much accomplished as I was hoping.
Here is more info.
Key on, no volts to either post on coil(used test light for test)
I have headlights, LOTS of cranking power. Battery new last year.
I checked for continuity at ECU plug to there ends and all was good.
Batt ground to vr case good.
Batt ground to ecu case good.
I'm sure I did more gotta scratch my head.
I'll get to more investigating tomorrow.
Thanks guys.
Coil #'s for resistance good?
Coil wire good?(no continuity) 3900 ohms resistance?
Ya' probably went through this but...…………

Check that plug connector for the distributor as well.

After break- do we have juice at the coil with key on?

Step back, Steve.............LOL

What "doesn't work?"

1....Do you have lights, nice and bright? Head lights, dash lights, tail and park? Wiggle connectors, bulkhead, up in ammeter wire connections, etc anything dim? or intermittent?

2....Key on, measure coil voltage.........at the "key" side of ballast you should have "close to battery" with key in run. Wiggle test again........bulkhead connector, battery cables, ignition switch connector.................

3...It won't crank? OK you can jumper it.................but if there's no voltage at ballast, coil, that is "ahead of" yourself
