I have a CAT 304.5 with a odd problem. Sometimes it will not shut off. I've tried disconnecting every relay, the ignition switch, just about every other thing I could find. At first I had to stop it by pulling wire to the fuel shutoff, then I figured out the circuit breaker to the console would stop it, and finally if I pull the bulb to the alternator light that will do it.
I'm thinking that my alternator is bad, and that somehow, when it's running it sends enough power back through the bulb to keep the main power relay energized.
Before I spend a couple hundred on a new alternator, does this sound right?
