I have a Craftsman 5hp 30 gallon compressor(oilless)..started taking a few extra seconds to come on and now will turn over a time or 2 slow and throw the breaker..replaced the 400-480 MFD start capacitor and didn't help....you can take the chk valve line off going into the tank/gauges and it will start but still sounds weak...has another cap..with 3 wires...figure it maybe the run cap....don't want to keep guessing spending money..any ideas?
