I have a 1986 760T converted to R134a. I would like amke sure the amount of R134a in the system is correct. The 700/900 FAQ list 30-40 psi low side and 150 psi high side at an ambient temperature of 85F. Ambient temperatures are in the 60-70F range now. How do I adjust the system pressure checks for lower ambient temperature?
