I have a 1993 Gottlieb Doctor Dude, and for the life of me cant figure this out. There was a batter holder in the cabinet no wired up to anythint. There is also a battery holder on the MPU so I put 3 AA in the battery holder and no go!!! Everytime I turn it on it revert back to factor settings. I also noticed the build in battery storage wires are not connect to anything. How would I go about getting battery to work on this machine...PLEASE HELP!

Also the left side of the bulbs are out...I have tested the bulbs and they are good. Is there a fuse I am missing to make them light up?
