I hate electrical

I also had a no spark issue other week. I had cleaned bulk head connectors several times, changed the ignition switch to a new one, some of the firewall part looked suspect. SOooo. I did run the big RED wire thru direct. Changed out the coil, points/condensor. Balast. The dist. was new a year ago. Nothing. Messing with it one day I noticed I hit the neg. coil post with a jmper bd also it th points. Then I had spark I also hate electrical as I SUCK at it, and I have no idea why I then had spark out the coil and at plugs. It runs again!!
Anyway!!!
