Where it gets tricky is the Compressor will compress both Freon and Atmospheric air. You need to purge some Freon out of the system if High pressure is indicated. However, if the compressor cuts out a Second time with the Low pressure switch bypassed, the system is probably overcharged and the HIGH pressure switch is cutting off the compressor. If the compressor works better and does not cut out, it can still be low on Freon or have a bad Low pressure switch. You can jump the connector with a U shaped wire and bypass the Low pressure cutoff switch. Just change this switch which will come out with only a slight puff of Freon being lost. Sometimes the Low pressure switch will get weak and cut off the system too early. The high end pressure switch will do the same thing for extreme pressure. The Low pressure cutoff switch will disconnect the compressor if the pressure is too low. Hello, You need to check how much Low end pressure you have.
