Aa/c clutch kicks in when started but kicks out almost immediately. The low pressure is 250# with the clutch out.
High side static pressure is 300# cluch out. It seems the clutch is not receiving power. Checked fuses and relay all seem ok. It seems like two circuits. Any thoughts?

The low side pressure is WAY too high. It should be around 50. It sounds like the high pressure switch is shutting things down, most likely the result of something which is plugged.
