Harvey,
If the pressure switch fails in the "closed" position, the pump won't
shut off and will labor as you described. I'd think that it'd eventually
blow the fuse or circuit breaker.
Another check that you can make is to connect your ammeter in series
with one of the pump leads: it should draw about 5 amps or so. If it
starts out lower, then rises to higher than that, it would indicate that
it's pumping too much pressure, overloading the motor. You might get a
rough idea if it's over-pressuring by opening a water faucet.
