I am having the same problem with my System 11C Rollergames. When three of the flashers fire, each one of them triggers a separate coil at the same time. Flasher #5 fires VUK, Flasher #6 fires Drop Targets, and Flasher #7 fires Cabinet Knocker. The coils work separately when they're supposed to and do not fire the associated flashers. I have 8 month old main power board, aux power board and interconnect board. When I disconnect the flashers from the interconnect board, the problem still happens. Any thoughts? Did you fix Big Guns? Thanks!

That relay appears to only control GI lights. I did some diag anyways and swapped it for the relay that controls the back glass illumination in the back box and it behaved the same. I unplugged that relay completely and the GI's drop out and the flashers and coil misfires happen in the same way.

Thanks guys, I suspect the Relay on the Aux Driver Board as well, I'm just in disbelief that I have two totally different Aux Drivers that have failed in the same way. Is it possible that something is causing these A/C relays to blow?

Grumpy - yes you are right, it's flasher #4 that's linked to the VUK and 5 is unused. The OP hasn't come back yet, I just hijacked his thread.
