AC Troubles - Hard Start cap? Something else?
Okay guys, new member, long time lurker. The missus and I finally bought ourselves a 5er, a 2004 Terry Quantum Ax6. It's huge and we have had it out a couple times. Got a great deal on it and we lo...

Alright. Update. Got my new parallel cable and generators are running good. Tried the AC right off the bat and got it to run. I was really grinning at this point but I knew that the real test would be cycling the compressor. I switched the AC off then back on, waited the required time, listened to the compressor come back on and... Overload.
I gradually started turning various other 110 loads off and trying again and again and again and I never could get it to fire. At one point, I have the converter, fridge, and any other 110 loads I could think of and it would still kick out.
At this point I decided to check the caps. Fan run cap tested low, but within 10% of nominal (7.0 uF actual vs 7.5 nominal). Compressor run capacitor also tested low, but within 10% of nominal (56.4 uF actual vs 60 nominal).
Compressor start capacitor, well, not so good. I will try to get pictures later tonight but it had a nominal value on the side of (47-56 MFD). I'm going to assume that is milli Farad? Or is that also micro? I tested it at 51 uF, so it kinda matters which one because it's either dead on or way off. The part number on it is 1497-090.
I will try to get pictures.
Edited to add - the start capacitor had a resistor across the terminals. I un-soldered it before taking these readings. Neither of the other two caps had resistors.
