Certainly check for power at the clutch, and if you have pressure in the system you certainly can power it with a 12V line for long enough to check the pressures. If there is low refrigerant in the system, you will starve the compressor of oil so don't run it very long if the high-side is too far below specs while running.
Do you know if there is a compressor speed sensor on your car? These can be problematic from what I hear. I don't have one on my '96.

Matt,
Good point - it's hard enough to get hook up the high side when the system is off. I will put some juice to the clutch and see what I get and also check out the pressures if that works. I don't know about the speed sensor, but i will find out. Thanks!
Mark
