This is just a test to see if the clutch engages and the system has the correct amount of refrigerant. You should not drive with the car set up like this since the system is designed to cycle off and on. With 12 volts jumped to the compressor, you eliminate the cycling of the system off and on. If he has a bad aux fan the high side pressure will build to the point that you can blow out the condensor coil or a refrigerant hose. The high side sensor prevent this from occurring, but it won't do this if you have the system jumped.
Another shade tree mechanic fix. Fix it right or don't fix it at all. From you previous posts I see that you are taking my advice about not fixing stuffs that breaks on your X.
