Powered it up and it runs well I did not try the pressure on/off switch since that would require mu to rewire the magnetic switch that I use to test motors 

It does not come with a magnetic switch when I test ran it the compressor it ran well no Knocks or od sounds ran nice and quiet for one of these, I do have a video but am unable to upload it at time of listing due to poor internet quality. 

 

The motor is missing the wire box cover plate the gauge on the tank works but is dented and missing the face cover.
