Alot of people don't know that you can get stray voltage from the ground leg, this could be caused by improper wiring in the house or even a faulty transformer. We had this issue with our boat lifts, the soltution was to electrically insulate the motor (which the frame is grounded) from the rest of the metal on the boat lift, the utility also changed the transformer to our house. which brought it down. We could only measure about 5VAC, but that was enough to give you a tingle if you were in the water and touched the boat lift that was above the water.
