Yep. That’s the very thing I got going on. My inverter keeps kicking off and my batteries are over charging. And then the apu shuts down and the alt code pops up. Thanks for the video.
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.
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
Well I’m still struggling with mine. Changed the alternator changed the batteries traced the wires. Still getting the alt code after a few minutes running and the inverter is showing 15.6 volts. Too high. My control box doesn’t have the little white test port.
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
Here's a weird one. My tripak evo stopped charging the batteries. It still runs and isn't throwing any codes. I changed the alternator and the plug that goes on the bottom of the alternator with the sense wire. Now it's not only not charging the batteries still. When I turn the unit off with the three knob controller in the bunk it automatically turns the fan on. Why would turning the apu off cause it to turn on the bunk fan automatically?
@@truckercarlson9081 sounds like a computer board issue, It still thinks the alternator is charging or it’s getting a voltage reading above 12.8v or it would shut off and throw a code, Also, the sense wire is not the one with the plug on it , It’s a smaller wire that hooks on with the big charging wire off the alternator, and pull that one off and test it with a multimeter to see if there’s a reading there if there is the alternator should turn on and off like it supposed to if not it will just continuously run thinking the batteries are dead
@@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
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
@@龙-g3q check your power cable , did it break or have you lost connection at the battery with corrosion? Start at the battery box and Work your way to the APU , the main power cable runs to the alternator and then from there to the control box
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.
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

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?
@@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
