Tripac apu alt code no start

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

 

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.

 

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?
