No Power at Irrigation Pump
My irrigation pump was running fine until it tripped my breaker twice over the course of a few days.
Now it won't turn on at all.
The power is on a dedicated circuit, dual pole 20amp. It comes out of the box to a switch and then in the ground and to the pump.
I used a meter to test the voltage at the pump and it is zero. At the switch, it is a constant 240.
Is it possible to have power at the switch, but no power at the pump and have a happy breaker?
If their is a short in the ground, wouldn't the breaker stay popped?
Thanks in advance.

I checked the voltage with a volt meter. The switch on both sides measured 240 when on, zero on one side when off. When I checked the pump (at the connection) I got zero or nothing. At the pump I checked the wire itself as well as the connections.

Sounds like the wiring between pump and switch,is it in pipe?it could be a high resistance ground in which case it may not trip the breaker.
