Thermo King Tripac Evo question: Current Charge

My Thermo King Tripac Evolution is reading a current charge around 246 amps. This number seems to stay around 246 regardless of weather the engine is running or not. Should this number be 0 when the alternator is not running? I've noticed from videos that current charge amperage is around 10 amps normally. My Charge Current Shutoff Value is set to default 12 amps. Does anyone know what this issue is?

Also, I have noticed when the engine starts because of low battery voltage in standby mode, it will continuously run until I manually turn off. It will not recognize when the batteries are charged and shutdown. I would like it to turn on to keep batteries charged but not overcharge.

 

I just got new batteries and cleaned everything up 2 months ago. I noticed before changing batteries, it would constantly charge. It would run for 24 hours if I didn't shut it down.

 

I did replace the alternator 6 months ago. It appears to be working fine. The voltage is above 14 volts when running.

 

It is correctly sensing voltage. Amps don't seem to change. Dealership was my last resort. Trying to see if anyone knows how to fix this. Thank you.

 

Thanks, my fear was it's the control module. Already replaced it once on this unit and unit only has 4600 hours. First time was under warranty. Thermo King is such garbage and the parts are so expensive.
