Is there a way to test my MSD ignition? I cant figure out why my truck wont run when I hook it up. I took it out a while back trying to figure out what was keeping it from firing but later realized there was a hole burned in the rotor button, and now im trying to hook it back up but it wont work anymore. I have it hooked up the same way, there is power going into the box and its grounded, I cant undestand why it wont work. Is it possible it shorted out some way which could have caused it to burn a hole in the rotor button? I need to find a way to test it to see if I need a new one or if im just somehow hooking it up wrong.
