Dont know yet, I just put my 3rd dizzy in, and also a new control/power transistor in today. It started right up and had about a 15min. test drive. Nother went wrong on the test drive. I also had taken out my amp before the test drive (thinking it might have been allowing a surge of power get to the the dizzy some how. I am planning on driving it to work on monday, about a 45 min. drive. I also cleaned all grounds, and took off my ground for my amp. I dont know if it was my power transistor or the amp that had been causing me my problem. I dont have a capasitor for my system, but I did install a fuse between the battery and the amp. The fuse had not been blown, but it is a 50amp fuse. I will keep everyone posted on how it went. Im going to be if it was my amp. I have installed many amps in the past and had never ran into this problem. Im affaird to turn the radio on yet, want to see how it runs with out the face plate even on. When I looked at all the grounds there wasnt any white/green crap (cant spell) around it. But thanks to everyone that had input on this. I think it was the control/power transistor the whole time, got it from advance auto parts store for $114. I hope this helps anyone having the same problem.
