about twice a day compressor shuts down with a motor overload fault I can reset and start again but something is going on. I have tightened every wire on every component available changed all filters changed oil and checked motor wires and nothing seems to help.

Many things come to mind. Anything else pulling power from the same circuit when the compressor is running when it goes into overload?

Oil in good shape and topped up?

Is it at the same time every day, or the time varies?

Air end wear....? Anyone else have one of these puppies that can help Bill?

Cheers,

Bill
