I just got a new centruy pump motor. It didn't come with a power cord. I took the cord off the old motor to use on the new one but the set up is different. There are no wiring instructions so i'm not sure where each wire goes.
I wired it according to a video I watched. When plugged in it spins and hums smoothly but once attached to the pool it speeds up and slows down. The hose from the pool shrinks and expands. Someone that thought they knew what they were doing rewired it but got the same results.
I desperatley need help. My pool is turning green.
