Russ,
My 12V air compressor does not have a dryer, but I don't think cycling it one or two times to test the compressor is going to introduce enough moisture to make any difference. If you start the engine you still have to drop the pressure enough to cycle the 12V air compressor, which still doesn't send the compressed air through the dryer. I just open the air release valve on the air tank in front of the passenger side drive wheel until the air pump cycles. I do it twice. That pump only compresses the air to 50 psi & runs for maybe 20 seconds.
