Hello. I responded to your original question. What does your volt gauge on the dash read for voltage when you are running the engine ay all rpms? Do you have a volt meter so we can do some voltage testing?

Expert:  Tan replied 1 year ago.
The alternator is 12 volt and you should be reading 13.2 to 14.5 volts. The ignition coil will get pretty warm. Is the coil actually shorting out? What is the ignition system you have?

electronic ignition

Ok we need to check the voltage at the ignition coil when the engine is running. Check at the positive side of the ignition coil. It must not exceed 12.5 volts. Is this Prestolite electronic ignition?
