I thought I had this problem licked. Race one at the Worlds last year I fried an alternator, second race developed a miss but also had fuel filter problems so I didn't concentrate on the miss. Over the Winter I notice that the nut holding the battery wire at the starter, using the large ceramic looking fuse had welded half way off against the block so I removed the fuse thinking that what may have fried my alternator. Now to the problem. Starts fine, rev to 2000rpm to energize the single wire alternator, charges fine, get on plan and with ever wave I hit I get a miss and the volt meter drops to 0 then back to 13 or so. Checked grounds, battery wire its as if you turn the key off for a split second, its not the plug either. Could their be some kind of short in the new alternator, could the module or the Thunderbolt ignition do this? Any help would be appreciated.
