Here's the coin mech switches on my Liberty Bell which will be the same. She still has the plastic covers which are usually long gone. Also, I disconnect one of the leads on the lock out coil as it's not needed anymore and just adds more noise. Keep the inner switch of the make or break closed and the rear open and put the player unit on free play as described in Clay's guide. Normally the coin drops and toggles the switch to its rear contact to add credits. Not needed anymore in free play.
