I would have called a professional a long time ago but im 2+ hours from the nearest city, would be cheaper to buy a new tub, Also I'm not incapable of following instructions I'm doing the best I can with what I got, sorry I don't have a "LARGE" knowledge on tubs like yourself.
The motor had the wet end rebuilt and bearings replaced.
I tried disconnecting the white wire from circ pump and it didn't make a difference in the pumps activity.
I did switch red and black wires and the pump starts/runs and turns on/off on high nicely, just missing low speed buts doesn't lock up and hum, the only issue seems to be the low speed.
I will hook my volt meater up at pump and see what I am getting.
