I tried a replacement pump that was used from a friend - had been working at her house but didn't get it working at mine.
The problem -- hum instead of movement. I realize this is probably a capacitor which I would fix but I also have some reluctence to try as when I was investigating the lack of spinning impeller, I touched the water in the basket filter and recieved a fairly nasty shock (220)
So.... I didn't notice until later that the ground attaching to other pool parts - the large gauage wire attached to exterior of pump via screw was not attached - would that be the only thing causing the current or would there also have to be a live contact to the metal somewhere that's causing the flow.
I can't see any reason why there should be current in the basket - the wires are correctly attached, no breaks in the wires can be seen touching frame or another wire and there is no water leakage where there shouldn't be.
