I thought my compressor had locked up…when i’d switch it on the relay would just hum, I replaced the relay and the same thing. So I replaced my 380c with a 480c and the same thing… just a little lost, everything has worked fine for about 2 years
Have you checked your wiring? All connections made, good grounds, no blown fuses, and no wires cut in two? I also recommend putting a meter on the leads of the compressor check to see if you are getting 12v
I had the same problem and ended up having a wire that was cut in two under the truck.
I have to retrace all my wires, but It’ll have to be once this hurricane gets out of here…thanks for the help
Like The Beast said, check your grounds and fuse.
Hope it’s one of those since chasing down a chafed wire can be a PITA.
Stay safe riding out the storm
Hopefully I’ll get a chance to try and track it down tomorrow at the firehouse, thanks for the suggestions
Welcome. Thanks to all fire fighters for their service because my dad was one! Check the pressure switch too!
Thanks for the help guys…got it figured out, redid my ground and replaced my pressure switch back up and running
