well it was blowing the fuse til I overfused it. lower center pop getting stuck on was the problem. still is. compared readings on all the T 03 case transistors on all the pop bumper driver boards and there are no shorts. I'm guessing there are pre-driver transistors on the driver board in the backbox so I pulled that out and just tested a whole bunch. there are no obvious shorts. unfortunately the pdf manual I have for this is useless as usual so I have no idea what drives what. i have to order the coil cuz i smoked it and had to bust it apart to get the pawl out . just looking for some advice/experience prior to ordering it. i have an aftermarket driver board but I dont want to smoke that too. i'd rather put in a few transistors etc
