Quoted from Mopar:Okay, I would first check the switches in both the 1st and 2nd Shot Relays. When both are in the energized
position, both have a set of switches that are closed. You'll want to clean and make sure the switches have
good contact..
Given there is a paucity of learned operational info available about ball bowlers I have found your posts in this thread extremely helpful and have 'filed' for future reference. Although I have found pinball schematics ok to navigate I cannot say the same for those for ball bowlers so your info is to me particularly helpful. Thks Mopar.
