I just made this video that should help lots of you solve MANY intermittent problems with the Gottlieb System 80B games! (Unlike System 1 and System 80A games that had a different reliable return ground, this fix starts with Chicago CVubs, and then Bounty Hunter, Rock, Tag Team Pinball, Genesis, Raven Hollywood Heat, Gold Wings, Monte Carlo, and ends with Spring Break. Any game that uses the SQUARE Molex Connector. (Starting with Arena, they used a long molex connector.) Its been tried and proven for TWENTY years!! Costs $5 and takes 15 minutes! Watch and learn!
