APU Reset

Was you using the engine block heater extension chord or the hotel power GFI plug in. There is a reset on the GFI, which I'm sure you already tried, a reset on the display and two resets on the firewall of the Apu. With the lid off. (Not the diamond plate) if you look on the back under the fuses follow the firewall down the back of the unit and you'll see two red reset breakers.

I actually have a few more suggestions but try this first. But I doubt your generator is actually bad.

 

did they ever look at it or diagnose it

 

But other signs your generator is "out" but not really. Bad generator capacitor, broken ground, broken positive wire generator needs flashed. I've seen all these. Only had to change generators because bearings were going out and or they were locked up. Also make sure you're link belt is in good condition.

 

if u take bottom cover off theres a red push reset button under on bottom right but i thought if that was tripped it wouldnt run at all

 

Yeah 30 amp and 15 are on that fire wall. Just right and down of that controller you mentioned. 20 amp fuse is for the 12v to the board and 15 amp fuse is for overheating issues it runs your radiator fan.

 

did you have the heat goin and the lites on when you had the vaccum goin, that couldv blown it
