Finally starting to make some progress on the A/C project in the tractor. Again its a R12 system converted to 134. The compressor seems to be fine after I overcharged it the first time. Now I am working smarter adding it with the guages and as vapor.
Currently have about 36 ounces in the system and its still low. The sight glass still shows air bubbles and the low side pressure is only 15 the most I have seen so it cools good but will freeze the evap coil like that.
The real problem though is the high side pressure is up to 190 on a 70 degree day. Checked the condensor coil and its clean.
So what gives what could cause the high side to be so high like that and the low side so low?
