See attached picture. Came in this morning and found no shop air. Here's what I've tested so far:
-Proper voltage is supplied. Breaker is not tripped, no loose wires, etc.
-At the contactor, I am getting continuity between L2 and the back red wire as well as L1 and the back blue wire. I'm no expert, but I'm pretty sure those back two terminals are the ones that when powdered activate the contactor?
-As far as I can see, there are 3 safety switches. The pressure regulator, the thermal overload, and something that goes back to what looks like an oil filter? They are all wired into the back red and blue wires at some point and all 3 of which are showing continuity across the terminals.
-When I press in the center of the contactor, the compressor starts, but stops once I release the button.
So as far as I can tell, everything seems to be working properly, maybe just a bad contactor? It was replaced less than 2 years ago when I did a voltage change on the compressor (from 480 to 240). I just don't want to order a replacement if I'm not guaranteed that's the issue. Thoughts?
