For those of you with scs frigette units, do they have taps for measuring pressure OR are they sealed?

A stalled condenser motor could cause what you are seeing. First, the stalled motor will cause a higher amp draw by it self, and the as we have talked about earlier, the compressor amp draw will climb sharply if the condensor fan is not blowing because the head pressure will spike. Gauges will tell you what is going on. It's hard to diagnose an ac problem without both electrical info AND refrigerant pressure info.
