I have 85 lbs freon compressor off I jump compressor low side goes to 45 its 50 degrees outside....I cycled the system no go...ware should I look? I have a multimeter and test light

Check the high pressure switch wire, mine has broken a couple of time. Start at the switch, it should be up at the top of the radiator on the passenger side at the condenser line. You will have to pull back the split loom and have a look.
