I'm having a different problem, sorry to go off subject from your topic but I have a matchbox dizzy and I'm burning through coils I had a MSD blaster 2 coil and it lasted about a week and went out I bought another one and it drove down the street and died, so I took my dad's old point coil and plugged it in and it fired up so I know it was the coil that went out that lasted enough to get me home and it died again so any suggestions?
