I have a Baldor 5 HP motor on my compressor that just gave up the ghost.I put in on in 1993,when lightning got my last one.It just gives out a loud hum until the breaker pops.One of the capacitors on the last one was split open and burned,so I figured I would take a look at these before I replaced the whole thing.I took the cover off and found three capacitors,two are plastic bodied and one is metal.I also found that one of the wires was pinched to the metal capacitor,and was shorted.It looked like it had finally wore the insulation away enough to short to the housing.All looks to be fresh arcing,and this motor has never been opened up until today.This was a factory assembly defect.Would that short fry one or all of those capacitors? I don't believe I've seen three on a motor like that before,with one of them being different.When I bought it I got the motor that would start under a load.It has been perfect for 25 years.
