This is on a 68' Barracuda 410 with Mopar orange box that I just put on. I had the MSD 6AL Digital system on . I did all of the test from info online for the MSD and it proved to be bad. Put the orange box with Mopar distributor and I'm having the same issue,,, no spark at all. Battery good, ballast resistor test good. Maybe distributor not grounded good. I'm sure it's something simple that I am overlooking.
How did you test the resistor?
Forman open or ?
Recently had a no start/no spark situation. Tested the ballast - it had voltage at the wire coming in, where the red wire for the MSD was attached. I assumed that was good enough.
I “ tested “ the ballast and it showed continuity. But the core was cracked. Replaced it and the vehicle started right up.
Looking at it again, I should just bypass the ballast.
