Roof AC shuts off with engine running
Hi folks, Here's one that has been puzzling me for a while, and today I decided to trace down the cause -without much luck, but I'm getting closer. I have a 2002 Bounder, with two roof AC units. If I...

I know you've all been waiting for the latest results, and more pieces to the puzzle. I checked the generator voltage. 120.2 V. With the AC on - back, front, or both, we jump up to almost 121 V. Let's call that a dead end. Purring like a kitten...
Engine Alternator voltage: 14.6 V, with the generator on as well, or off. Maybe a bit high, but possibly not for all that it powers.
I'm starting to think it's time to hit the roof and look for a problem in the unit itself, relays, and possibly the fan/compressor relationship, since the front AC wants the back fan to operate before it will turn it's compressor on. (With the engine running and using generator power anyway)
I did try unplugging the 12Volt converter during all the process, and there was no change with that either. Apparently all that does is keep the batteries up while 120V is available.
Sheesh! It worked correctly at one time....
