Mr. Pinball Tip:

If you have an EM pin that always stays on the same ball, there are several things to check. On single player games check the ball count unit. Make sure the rivets are clean (and the wipers are contacting them), the step-up/down coil plungers are not seized, and the spring is not broken. Manually operate the stepper to check for smooth operation. On multiplayer EMs, check the player units for the same things. Also check the ball return/outhole switch, which tells the game the ball drained. Another source of this problem is the ball release trough switch. I recently picked up two Gottlieb multi-player pins which both wouldn't move off ball one! Cleaning and adjusting this switch did the trick. Try the above before moving onto relays, etc.
