Hey Rich, thanks for those steps. I will definitely check the breaker itself as you described. I did however try to connect it to the input side of the breaker directly with nothing happening. So even if the breaker is bad, it was out of the circuit. I definitely need to find out what voltage I'm getting at the breaker panel though.
I'll check it with the multimeter hopefully today if I have time.
