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?

Check the pressure switch (if it as an external one like on a well). It may have some corroded contacts or burned wires where they attach to the switch. Otherwise i would guess the run capacitor.
Is it on a dedicated breaker? If so check the voltage, the breaker may be going bad and giving trashy voltage causing the slow start.
