Pump motor failure

Thanks everyone for the help.

I found the circuit breaker was bad. Took it apart and found that the phenolic case had cracked inside and one of the contacts had broken. Not sure how it was still passing voltage.

But everything is running

Interesting.

It's sort of ironic, that with 'old tech' -- an old-school multimeter with a needle -- you would have likely solved the problem much more quickly, since that meter would likely have shown low, or no, voltage.
