In this HVACR Training Video, I show how to Measure Resistance Readings on the PSC Compressor Terminals in order to determine which tab is Common, Start, and Run for Electrical Wiring when a Diagram is not available. I also explain how the Ohm Readings add up and how to Check for a Short in the Windings to Ground. A UEI Digital Multi-meter is used for testing. PSC Motor means Permanent Split Capacitor Motor. This type of electrical motor needs to have a capacitor wired connected in order to start and run when powered. This method can be used to Ohm out a Compressor, Blower Fan, Inducer, or any other type of PSC Motor.
