    Hey
    So im repairing a bally big time that followed me home. I would like to under stand three settings on the back door that are labled corners, roll overs and extra balls. All three have labled terminals L M C. My roll over switches do not score as its set now , but they light up. I never messed with where they were.

    Liberal, medium, conservative adjustment to set how frequently these features are lit

    the plugs just change the odds of getting the feature to enable. On machines with a reflex adjust plug, that increases the odds of anything good happening.

    to make the game liberal, you want to connect as many wires between the plug and socket as possible. Most games don't have the LMC on the tags.

    ball going over a lit rollover should cause the spot 25 or spot 10 trip relay to trip (schem B22). Odd circuit that goes thru the sounder/knocker coil as well so the game makes a loud thunk when you hit the rollover.

    if both the rollovers aren't working, check the sounder coil and shutter cam 4B switch, then plug connections.

    Hey there! Got a moment?
