Got PCB from brothers truck air conditioner unit. It seems to be Waeco CA-800. So far I have discovered it is 24V powered unit, obviously with step-up transformer - transforming most likely to 230 V for compressor and maybe also the fans (at least two fans in there).
From what I know, board is defective for most people with this unit and it is supposedly worth of at least 400 USD/300 Eur, so you can see there is some point in repairing this thing
In this case it is supposedly dead, connecting it directly to 24 V resulted in burning two fuses. I have nothing but camera with me here (at home now) so I will clean it and take some pictures for you guys, than I will check all the diodes/rectifiers and transistors when I will be back to my "lab"
Stay tuned!
