I have a 24 volt ignition system in a pinzgaur 1973. I was wondering if anyone has any insite as to why I have gone through two coils in three years? There really is nothing in the system exept 24v ignition switch and a radio noise suppressor. Then of course distributor,pertonics ignition,wires,and plug wires. The coil is a military waterproof internal resister. Any commenmts?
