I had the yellow triangle and then red triangle run for 20 minutes or so. I'd restart the APU and it would run for 20 minutes and shut off. I was told by a thermo king dealer that i needed a new a/c compressor. Or freon is low. I let it go for some time. A friend of mine worked for that thermo king. And quit. I asked him what's the deal. He said 90% of the time, it's a ground or loose connection issue. Because of dirt and calcium chloride. I spent couple hours taking connectors apart, cleaning them, and reconnecting. After all connection cleaning, alternator connections, and major ground to frame, it fires up and works just fine
The truck I bought had a Tripac system on it, but they removed the APU and just hacked all the wires and lines at the edge of the cab. I started to look for a used unit, but decided to go with a new Green APU instead. I'll be removing all the components to save paying the installer's to do it. Plus that's parts I can sell instead of letting them have it all. The board in mine looks totally different than yours. Mine has a date code of 4208.
what could be the reason? My power button on the panel stopped turning on? the backlight lights up as if it was turned on normally, and then the backlight turns off, I checked all the fuses, everything is whole and unharmed
@@woodssr74 it looked easy. Didn't take long, but I was just watching. Holes were drilled in the dpf a plug was unhooked on the board and maybe something else? I have to manually turn off now or apu will keep running with truck on
Thanks. That I know but at minute 2:10 you’re literally saying that is running on standby mode and showing it running. So I’m wandering how is that possible
Sikeston TK is the bomb!!! Great people. They serviced my APU this past summer 2023.

On my compressor cable I’m getting 7 volts, I think I’d be getting 12+, what could it be?, thanks, great video.
FYI, That's a revision 1.6 control board. the revision 1.5 board is completely different.
Yeah, I just got all 4 of my batteries replaced. And now it's not even turned on.

Hmmmm not sure I would take it to Thermoking and have them look at it
How do you run the apu without turning on the AC ?
You don’t
@@sturgelltruckingllc4074 lol, ok TY
I'm getting code 35 and found a popped 30 amp fuse. Replaced fuse and still doesn't start. I'm lost in more ways than one.
Try to get your hands on Diagnostic Manual TK 55739. It might help you find a problem.
@@ofilippov It was a DPF issue and we just ended up deleting and we good to go
@@supertrucker1356 I'm having issues with my old style thermo king apu
It has that dpf crap on it. Was it easy to delete it
@@woodssr74 it looked easy. Didn't take long, but I was just watching. Holes were drilled in the dpf a plug was unhooked on the board and maybe something else? I have to manually turn off now or apu will keep running with truck on
@@woodssr74 what's the issue?
How do you run the apu on standby mode?
You can’t, you have to turn the ignition key off on the truck and lower the AC temperature enough to get the APU to turn on

@@MrPaveles it’s because the APU was not sensing the voltage charge so it just keep running
tried googling your company - only got "sturgill" results not sturgell.
please post contact info , as i have questions about my apu sir
