Apu question

Having the same issue Kolorado was having. Sabe model apu (tri-pac evolution) push the power button, lights up then goes off. Oil, coolant, belt are all fine. I thought it might be fuse but unless he found a fuse somewhere else, all the fuses in the interface box under bunk were fine. Where would the reset button be at?

 

Well after reading this thread and a couple others, found reset button. Not really a box but a relay connection going to inverter. Two buttons, I turned off inverter pressed the black button, got a beep and a zero on the display. Pressed the power button and now it does blow, but apu not kicking on with it on cool but does blow on fan only setting.

 

Ok did more investigating. The inverter is only reading 12.9V so I think that might be the problem. Brand new truck though, didn't think I would be having trouble like this less than a month sheer getting it. I can run the truck for ac but it has that stupid idle shut down on it
