I am using an MSD 6AL, on a 69 Plymouth. Blaster coil, and MSD Distributor. Car ran great, but yesterday it sputtered and died. I left the ballast resistor in line, as I read in a couple of different places on MSDs website, and in the instructions that it was ok to do so. Doing some trouble shooting, I have voltage everywhere I should, so I figured what the heck, I'll bypass the resistor, and it cranks. So I reconnect the resistor, and it cranks. ???? Examining the resistor, it's broken inside, could this have taken me down? I mean to where the engine wouldn't even turn over?
