Williams Base hit knocker

[Ant16bar2]

Hi I’m having a problem with the knocker on my Base hit machine when you win a game the knocker should go off mine doesn’t is there a leaf switch on The credit wheel that makes the knocker energize

The knocker switch is on the credit unit. It is a NO end of stroke switch that activates from the advance coil arm. The switch is found near the bottom of the credit unit.

All of the switch openings and closings gaps look good, but its the dirty points are the concern here. File cleaning and gap checking for every switch as part of the shopping out of the machine should be done.
