    I want to energize the E coil. How is it possible with this ladder logic assuming the W and 2B contacts are already closed?

    Assume a ball drops into hole #9.

    Quoted from MarkG:

    So, what game is this?

    1952 Hit n Run. I don't have the game but was helping a friend long distance try to get it working.
    When a ball lands in a hole it remains there until the start of the next game. Yes, landing in a hole should award points, the E relay being the 500,000 point relay.

    Quoted from MarkG:

    if numbered normally open and normally closes switches really are in series, E might fire only very briefly if the two switches are configured to make before break

    but even this wouldn't make sense because the switches wouldn't change state even briefly unless the E relay energized, and that can't happen unless one of the relays 9 thru 12 energize first.

    I think it must be as you say, the hole switches are in the E relay circuit.
