does any one have a copy of a/c wiring diagram with the values of each wire the ohms and volts or is that possible . I'm thinking I'll trace each wire from switch to compressor until I find what's wrong .

The old R-12's would be ideal at 30-35 low and 150-160 PSI high. R-134A is ideal at around 40-45 low side and 170-185 on the high side. It's possible
that you may have too much pressure, or the gauge set is inaccurate. if you don't have at least 45 F at the outlets, something is amiss. I always get
38 to 42 F at the outlets when I am done. Even converting old R-12 systems over to R-134A, I have gotten less then 45 F degrees at the outlets.
