Compressor / mag motor control issues

Thanks for all the suggestions. I bypassed the contactors, and the issue went away and the motor ran smoothly but there was still a loud ticking. I still had the coil in the circuit and I could hear it opening and closing the contactors that was causing the ticking.

I then disconnected the coil leads and it just hums along like it should with the contactors bypassed and the coil disconnected with no ticking.

Thinking it might be the pressure switch since that activates the coil, I bypassed that and put the coil back active and it was opening and closing about once a second with the ticking.

I didn't see any obvious wear signs when I had it apart. Is there any way to test the coil with a voltmeter?

Thanks,
Scott
