All bearings move freely but not smoothly...DLB wrote: Fri Mar 19, 2021 5:56 pm Remember not to apply power for long, if there is a start problem then the run windings are getting hot and this can lead to worse news.
If your circuit breaker is tripping almost instantly when you turn it on that is more likely a short circuit, either in the motor or external wiring. If it takes a few seconds to trip that is more consistent with the start circuit.
I don't think you are ready for this yet, but very good used motors go for under $200 on eBay. You might also look locally and avoid the shipping. And some people here might have one, so let folks know where you are if you get to that point.
Speaking of windings getting hot, I did notice that the wires were black/charred/fused together in some places and broken off in others... I’m guessing this isn’t a good sign?
