Welcome. My name is ***** ***** would be glad to assist.
If you can post a picture, it may help.
But with a 220 volt coil, one line goes through the pressure switch
and back to one side of the coil.
The other line goes through the overload block and then to the other side of the coil to complete the 220 volts.
That is the normal on a starter. So, if there is a wire on the other side, follow it and it should lead to the overload.
May be tripped.
If it doesn't have an over load, it may have been directly wired to the 2nd phase.
Bel;ow is a link to an 8536 diagram I had on file. It is for 3 phase but they all operate the same.
Look at the wires going to the M-COIL
Let me know
