Auto Ac not cooling  

I have traced a possible leak to the accumalator, it doesn't seem to be a big leak since it has a small amount of oil around the pressure switch. However the clutch will not engage. I have checked the fuse and it is ok, I switched a comparable fuse from another working circuit. I think the low pressure switch has to clutch disabled. Can I use a jumper to make the clutch and then add refridgetant.
