I have just replaced my pump motor running a Hayward Super II pump. It's a Century 1 HP running on 120V. I adjusted/moved the wires set from factory from 220V to 120V and when testing (after connection), there was a small spark in the timer box and it tripped breaker. I'm sure I was connected properly, but couldn't imagine a new motor being bad. I wanted to switch to 220V, so I decided to replace timer with a new one hoping the timer was the issue. Upon installing the new 220V timer and connecting everything, the pump turned on, but will only run for a few seconds then shuts down. It does not trip the breaker. I tried turning on again and the same issue happened again. I noticed at one point that I heard a click from the motor and was needing some advice. Before the clicking noise, it would not restart, but after the click, it did start (only for a few seconds). Thanks for any help.
