Old Coleman AC
Sometimes this Ac starts and runs right but sometimes starting amps go up to high and it will kick the breaker. Wanted advice on if it could be the capacitors or the compressor going out. Thanks

RV AC seems to have a tremendous amount of misinformation on the net. I am no expert either and can only relate my experience and opinion.
41 amps. It takes decent equipment to measure the starting amps of an AC. The 41 may be right or close enough. AC has 2 amp measurements running amps and LRA locked rotor amps. A very brief less than a second amp surge from the start capacitor to kick start the compressor. inexpensive meters will not measure the LRA accurately or at all!
Need a meter that can measure farads to actually measure the health of the capacitor. Can be good but not good enough, like a weak battery. Be cautious with capacitors they can produce enough voltage to kill!
Tough call, circuit breakers can and do get weak, go bad. Capacitors can get weak. Compressor may need a hard start. No idea how to test a breaker? I can test capacitor.
cheapest easiest option is replace breaker and hope!
