Tripac apu alt code no start

I have a 2015 tripac evolution.. Control panel works - go to start it up, the buzzer and fuel pump go to prime to start and about the time the starter goes to fire off - it shuts down and throws an alt code with red triangle...

I am completely lost with this.. Maybe a bad ground to starter ? I have changed alternators multiple times. Tried 120 amp, tried 65 amp...65 amp is what came off and the one i have in there now. Checked all fuses, all are good.. Have 12.6 volts to sense wire on plug as well as same voltage inside the box... I have plugged into my laptop and it wont show any codes...

Anybody have any idea where i should start

 

@reeferwrencher do u know anything about tripacs ?

 

Best option set it on fire and get something else lol......tripacs are absolute junk. That said from experince one of two things are happening here. Either A and most likely is the computer is not reading any signal from the alt and thinks its bad in which case you need to check wires, belt and so on....or B and as happened in mine the new alt caused the computer to cook and get ready to pay $7500

 

I agree. I am about to drop it off the side of my truck and put a regular generator in its place.. Had to many problems with this thing... Do you happen to know where I can get a wiring diagram for this apu

 

Never been able to find one and TK demanded $2600 for a copy. As for an apu try green APU their supposed to be oretty good units with all off the shelf parts. Im actully in the process of trying to finance one+their arctic package to ditch this TK peice of ####. Took it into TK yesterday because of the overheat issues amd they want to sell me a whole new engine ECM compressor and wireing harness for $11,000 or i can go new for $23,000 SUCH a deal <extreme sarcasm here> meanwhile a green is $13K installed and uses a kubuta engine with honda AC parts. Most of which i have in my shop for our kubuta diesel generator and my dads honda.

 

That is crazy man. I think i am just gonna buy a cheap harbor freight generator and call it a day if i cant figure this out

 

Dont blame you and ive thought about it. The ONLY reason i dont is i live in SD where it gets hecking cold. So i want that arctic package and dont want to lug around a genny big enough to both power a block heater+tank heater+coolant heater and everything else as well.

 

Just curious how many hours are on that APU?

 

Sounds like a major power drop. Need to check voltage at the main power for the board,batteries and starter.
Does it have the 50 amp fuse close to the starter?

 

Not really sure to be honest. Havent ran it for almost 2 years
