Hello,

I just replaced my pump seal and then it started tripping the breaker instantly. I had the same thing happen 5 years ago and just replaced the motor and problem solved. So I just ordered a new motor AO smith 1.5hp just like the old one and same issue. I disconnected the wires and breaker stays on. I noticed the pump housing has a small dent in the side from shipping. Maybe 1/8 inch indention in the middle of the housing. Would that cause it to trip the breaker? I'm not sure what to do now.

Bottom left. If I disconnect the wires to the main pump motor (the new one with a small dent) I can turn of the breaker and the polaris pump comes on. If I reconnect the wires it trips instantly.

I'm feeling a little stupid right now. I had both wires connected to the top L1. I'm in cramped quarters and didn't see L2 for the little divider. Not sure why there are two terminals on L1. Now I'm questioning my judgement, should I give it another try with L1 and L2 connected?
