Ok guys i have a few questions regarding the recharge of the R12 system. First i do have a few 12oz cans of R12 left so this isnt about where i can get it. Second the system is completely empty as i had to replace the compressor with one of my spares, i used the recovery machine at work (thats all it does it wont charge it anymore). My question is how much R12 will need to be in the system before the a/c clutch will engage i made the mistake last night and ended up wasting a can because one of the older techs told me it shouldve engaged as soon as the charge line was opened. Please note i was not the one charging the system i had one of the older techs with a set of guages do it for me, and im just going by what he said. So before i even try charging this again and wasting more valuable R12 how much needs to be in the system before it turns on. If its not what should i look at. Ive checked the fuse, and the relay. The relay has continunity so it would seem. If those two are fine then is it the compressor?
Thanks for your time
