Spent a little time checking out some old electric motors for a neighbor. I put power to the motors to see if they're any good, but limited success. One just hums, the others spin, but four of the motors show voltage on the cases under power.
I opened up the junction boxes to look for wiring damage and shorts. Lots of cruddy feed wiring, but I cleaned up the connections with ring terminals. Nothing else obviously bad, but four cases still showing some voltage under power.
Any idea what to check next? Or off to the scrap pile? Any benefit to splitting them open and digging deeper?
Sort of humorous (to me), one of the wiring diagrams indicates "UNGRND". I guess that's the hot leg. I have just enough electric background to be dangerous.
Any guidance is appreciated.
