Points ignition coil leak

My 72 GMC will not fire all of a sudden, coil tests pictured, but have oil in the tower . this will prevent it from starting I assume? Lol

Re: Points ignition coil leak

I don't know what those tests are, but if there is oil in the coil tower, then yes, it is no good.

Re: Points ignition coil leak

If that's 1.8Ω on the Primary and the Secondary checks out, you might still have another problem

Agree that visible oil probably means that even if your coil still works it won't last long
