Hey all,

I just acquired a Shadow and am troubleshooting a gremlin. When both flippers are fired (and only both) the game will reset.. reliably 95% of the time. I've read that this is likely a power issue.

DC voltage at the game ROM on the CPU board is steady at 5.05VDC (+/- .03) before, during, and after the reset.

I know many people will automatically replace BR2 and C5 but, with the voltage steady, will this still possibly fix the issue?

I have looked at the flipper coils and flipper coil diodes and there are no apparent cold solder joints.

Any suggestions would be much appreciated.

Thanks! Ryan
