Try putting a set of points back in with a stock coil, that will elimate that stuff.I had a brand new pertonix and it fried as soon as power was applied the first time. Some one told me they would do that at times.They gave me a new one but haven't tried it yet.Crane also makes a brain box that goes under the dist. cap. The other stuff, ck switch and starter relay if its not the ing.
PS. do you have the light package on your charger?
