Im looking to get some ac going in my new to me 380 and am looking for tips to check and see if the compressor is good. The system has been changed over to R134 at some point. When I turn on the ac system the motor acts like there a load put on it but the clutch on the compressor doesn’t spin. I disconnected the 2 connections at the dryer and jumped them with a wire both with the key on and running, nothing happened. I also,put a test light on each of those dryer connections, didn’t show any power. Any other tests? Pictured are the connectors I jumped.
