Macktech689 Posted June 7, 2014 Share Posted June 7, 2014 (edited) The best way to check your compressor is to remove the inlet and discharge hoses from the compressor head and feel the air. If still no air pumping from the outlet check that the fitting isn't plugged with carbon, if the fitting is clear feel the inlet if no air is moving there the drive coupler has failed. If it feels like more air is being pushed out of the inlet than being drawn in the unloader in the head is stuck open.
