I need to replace the universal ignition switch in my car and I need to know what size amp switch to get. Painless has one like just like it in a 15 and 25 amp. I have a 327 with a Mallory dual point distributor converted to an electronic ignition.
6v or 12v? 12v uses less amps, and 6v uses more. what's the price difference? It couldn't hurt to go with the 25.
I'm sorry, its a 12 volt system. I'm not sure, but I think a 25 amp is for a 6 volt, and a 15 amp would be sufficient for a 12 volt. What determines the amp size? The 25 amp was around $19
