I've got a RCT that has been playing fine up until few weeks ago - The upper right flipper stopped holding - It has full power but immediately returns down after it flips. I know the Williams flipper coils have a 3rd lug for the hold circuit - These Stern coils only have two lugs and the top flippers don't even have an EOS switch.

Problem 2 - I'm playing last night and the lower left flipper stops holding - I investigated toady and found that the EOS leaf switch had broken. I replaced the switch and the flipper would machine gun even time it energized. I reversed the EOS wires and the flipper played normally for 1 game and then started to machine gun again.

Back Story - The Driver board was recently sent off for transistor repair for the upper right flipper - This coil has been replaced as well.

Am I looking at driver boards problems again?

I need a Williams to Stern translater
