Thermo king Tripac Sense Voltage & Reset Switch

[@macenglish220]

Sikeston TK is the bomb!!! Great people. They serviced my APU this past summer 2023.

[@MangatSingh-no1gf]

Learned a thing or two. Thank you for making and sharing this video with us. Much appreciated.👍👍👍👍👍

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.

Thank you. I learned something new today.

Thank you sir 🙏🏿

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

[@sturgelltruckingllc4074]

Hmmmm not sure I would take it to Thermoking and have them look at it

[@ricardotrujillo5106]

On my compressor cable I’m getting 7 volts, I think I’d be getting 12+, what could it be?, thanks, great video.

[@user-wm7ie4mq1q]

my apu worked fine all summer! and tonight from 6th to 7th of September it turned on! and when I turn it on on the instrument panel, nothing works, I checked all the fuses, everything is normal, I did a restart on the apu itself, nothing helped, I disconnected the main wire that goes to the apu computer for 10 minutes, and the instrument panel turned on, but not for long, somewhere after 2-3 minutes everything turned off again and the instrument panel again does not respond to turning on, what could be the reason? the oil is normal, and the antifreeze too

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.

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.

[@anthonyrich4763]

How do you run the apu without turning on the AC ?

[@sturgelltruckingllc4074]

You don’t

[@anthonyrich4763]

@@sturgelltruckingllc4074 lol, ok TY

[@DAREALCOUP]

Hold the power button until the control panel turns on and the red stdby light turns on. But don't don't turn the knobs to select a a temp or mode. It's then in monitoring mode. It will then crank up without running the ac when batteries get to a set low voltage to charge them back up. Hence the name monitor mode. It's monitoring the battery voltage only.

[@arsalhb]

so my tripac apu isn't throwing out any codes, but shuts off within 3-4 minutes with the red triangle (without blowing any cold air). I noticed the moment the condenser fan comes on, the system shuts down. During this time the alternator belt keeps rotating, but the clutch never engages at all. The APU unit also beeps at start. Any idea what this could mean?

[@sturgelltruckingllc4074]

[@arsalhb]

@@sturgelltruckingllc4074 i’ll check that up. Could it also mean a faulty compressor needing to be changed?

[@sturgelltruckingllc4074]

@@sturgelltruckingllc4074 does the compressor have to atleast turn on for me to be able to put in r134a?

[@sturgelltruckingllc4074]

@@arsalhb no it won’t engage if it’s low, you can just start adding until it engages and reaches the right pressures. That’s probably a waste of time if it has a leak.though

[@MrPaveles]

How do you run the apu on standby mode?

[@sturgelltruckingllc4074]

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]

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

[@sturgelltruckingllc4074]

@@MrPaveles it’s because the APU was not sensing the voltage charge so it just keep running
