Long time lurker, first time poster. hope you guys can help me out.
I inherited an old A.O. Smith ST 1072, 3/4 hp, model C48K2N143C2C, Hayward super pump II, 14k gallon pool, one skimmer, one return. there have always been bubbles in the returns. Tiny leak from bottom of pump. have unsuccessfully investigated other common sources of leaks. ordered new gaskets and replaced them yesterday, no issues during installation. although im not sure if i shorted capacitor bc im not sure that i got a screwdriver across the wires (but managed not to shock myself).
reinstalled motor. Flipped switch and saw poof of smoke and motor died. reset breaker (it had not been tripped) and pump worked for several hours. it shut itself off overnight. tried it again this morning and it would only work for a few minutes before shutting off. now completely dead.
thoughts:
#1 i rewired the electrical incorrectly. do not think this is the case. white wire to neutral, red to line, green to ground. its a 115V. it should be noted that the red wire covering was fairly frayed.
#2 shorted capacitor?
#3 incorrectly installed gaskets, leading to increased leak and failure to prime the pump fully. i didn't notice any increase in the size of the leak when the pump was running so i dont think this is it.
does anyone have any suggestions? im leaning towards just replacing the darned thing. thanks in advance!
