I picked up a fixer upper CFTBL, it has had a number of issues and these are the ones I haven't solved yet. Any help would be appreciated.
1. Creature Feature ramp diverter never lowers. It raises and lowers in test but never during multiball when the lamp is lit.
2. When random switches are triggered both flippers are fired. The switch that triggers it changes and doesn't happen all the time.
3. The All Lamps and Flashers test also fires the flippers and I have to shutoff the game to get control of the menu again.
4. During attract mode, there are random buttom presses. Mostly from the coin door service switches. Like the volume will go up a notch, it will say the "let me out" as if the flipper was pressed, enter the service menu. etc.
I suspect there is some battery damage to the CPU board that isn't visible, but wanted to ask before swapping boards or getting a replacement. Thanks
