Need to know what the resistances need to be to test motor

my compressor has problems starting up when cold. the motor strains and turns slowly until it pops the breaker. I don't use an extension cord and the outlets I use are usually strong. It does the same thing once full when it tries to re start. It will usually run ok once it gets hot. I was told it is the start capacitor. is that correct and is it something I can fix my self?

What is the sequence for installing the wires on the capacitors I've just replaced? There are four connectors on one of them and two on the other. I know that there is a connector wire between the two but am not sure about which is up ,down, right ,left, of all the plugs. Help?

My compressor builds to regulated pressure and the motor stops.
When the motor tries to restart to rebuild pressure, the motor stalls and the circuit breaker (black button) pops out and stops the stalled motor. It almost sounds like a car engine stalling when starting forward in too high a gear (standard transmission. Any suggestions?

I have power past the pressure switch, but my compressor won't turn on. I can't understand why.

My compressor runs and brings the tank and regulated pressure up and then turns off as it should. When I plug in an air supply line the regulated pressure drops to zero and then slowly builds up. It supplies air to the tools is in bursts. Is this a sign that the pressure reducer is bad?

I need oil, do you have it?
