Sanborn compressor ground screw wire does not tighten

Sanborn compressor ground wire problem. The screw that should tighten on the ground wire does not tighten


We are wiring our new compressor.

It is a 4.7 HP.

We are having trouble getting the ground wire to connect. The screw that should tighten on the ground wire does not tighten. What are we doing wrong?

Sounds like it is stripped, or you're using the wrong screw.

The one (4 on the drawing) on the pressure switch retainer (3 on the drawing) probably is the wrong screw.

You want one directly on the frame metal, which may already have a green wire connected to it.

Maybe send picture(s)? or hire an electrician.
