Quoted from splitshot:The Munsters Pro is my first spike game and I have found trouble-shooting to be more difficult. I am having an issue with Grandpa, Herman and Eddie loops not registering. Also, the ball will stay stuck in the Grandpa hole and not eject. Any ideas? Thanks
Go into the test switch menu and check each switch.
Then I would start by reseating connectors under the playfield. Maybe something shook loose.
