Ok, had a chance to check voltage to the coil. With key on run, mutimeter positive post on the + coil post and negative to ground I got .63 volts. That doesn't sound good at all. I should be getting way more than that correct?
Doesn't sound good EXCEPT......did you check is this actually the power wire or does this go to the distributor? And what does it read "in crank"? There are two different circuits in play
The key supplies power TO the ballast resistor, so that should be your next stop. From the ballast power goes to the coil + and then to the points.
'IN RUN' With the points OPEN you should read "same as battery" voltage at:
Both sides of ballast resistor and both terminals of coil. This is because there should not be current flow. If nothing, yank one wire off the ballast and re-measure
"IN CRANKING" Coil + should have "same as battery" during cranking and should be at least 10-10.5V. If points are opening/ closing, you should see "jumping" on the meter. But you ALSO should be getting a spark
