I just got one of the new Red Dot air conditioners (RD-2-4530-0) for my M920. Instructions with it were for an M915, for which I had to do a few mods to make it work, but I got it installed and charged up. The problem is the high side pressure was running to high, but cooling. I let out some of the R124a and was able to bring it down to around 175lbs, but then it doesn't cool. I charged it back up to about 225lbs and it cools a "little". I just now realized that the fans for the condenser unit are not coming on and coils were hot. Does anyone know where I can get a schematic diagram to help me troubleshoot this thing?
PS I could only find one circuit breaker, a 30a on the side of the evaporator unit inside the cab, and it was good.
