So last week I went to turn on my air compressor.
Nothing but a hum.
Tried to turn it by hand and it turns.
Ordered both capacitors.
Came in and same thing.
Took the back off and checked the starter.
Seems to be working.
Cleaned the contact and the flywheel switch.
Still nothing.
Put back the old capacitors and not it jerks while spinning very slow.
It's an old Craftsman 5hp, 220v single phase.
Got it in the 70's.
Any suggestions????
