    Unhappy score reels go beserk

    I have rebuilt a Gottlieb ProFootball. It has both score and points (touchdowns) score. The score reels reset OK. After scoring the first 900 points, the score then adds thousands and tens of thousands. On the points (touchdown score reels), the first point is scored OK, then it score 10s as well, eg 01, 12, 23, 34, 45.
    I think the 00-90 relay is also sticking. Any ideas?

    When the score reel reaches "9" it closes a set of points that completes the circuit in the next score reels points relay. If this is out of adjustment, it causes similar problems. Check the points in all the reels, make sure there is no grease or crap hindering the movement of the reels. There is more force required to move from "9" to "0" and then to "1".

    Look at you "10"s reel - it sounds like it is gapped correctly - ie. 10, 20, 30... what happens when it reaches "90" - Does it go correctly to 100, or 1,100 ??

    Watch the movement of the 10s reel..

    The second problem needs to be addressed after this problem.. If the 10s relay is sticking you may have a stuck switch on the playfield, or the switch stack in the 10s relay needs to be cleaned - with an old business card..
