I own a Gottlieb Eye Of The Tiger 2 player EM. The game appears to function normally for the most part, but has back box lighting issues. The general illumination is ok, as are the Tilt and Shoot Again lights. Neither of the score reels will light, and neither will the ball count lights or Game Over light. I'm guessing all lights in the box share a common ground, and the required 6.3v seems to be present at various relays, but without a schematic it's hard to be sure if they are the right ones. Also the ball count stepper at times seems to be missing the required feed to the activation coil to operate the steppr unit. After 30+ years of owning this machine, this is the first time a major fault has occured, and it's driving me nuts. Anyone got any ideas or suggestions?

Thanks Mark - yes you're right - the match feature wasn't lit either. As you suggested the AX relay was at fault, so problem now solved. The ball count stepper has also cured itself somehow, so all back to normal! Thanks again for the help.

Thanks for that - fuse is ok and Jones plug checks out ok for contacts.
