    So I've been reading and watching all afternoon about old Gottlieb relays but I can't find an answer to this.
    Game resets and starts just fine but is stuck on ball 5 through all 4 players over and over, game never ends. I tried some advice and switched it to a 3 ball game and it was the same except for, obviously, the ball in play stayed on ball 3. I'm torn on whether it' the BX or "last ball" relay that needs my attention........

    Does the BX / Last Ball relay properly trip upon getting to the last ball?
    Make sure the rivets are clean on the Player unit for this (and make sure the small flex wire is present where it should be between the sprung pins on the wiper disk).
    Then, also check that the contact stacks are tight on the BX/Last Ball relay, and make sure that the contacts are properly adjusted.

    Adjusting contacts on the AX and BX relays in Gottlieb EMs is a bit of an art - because there is not much distance that the armature moves - so the contacts adjustments are critical on those relays for proper game playing.

    Good luck!

    Nothing trips at all as it never gets to "last ball".....in a sense.

    It's always "last ball"......like Groundhog Day. I know the BX certainly doesn' 'click' like the AX does so I'll start with it.

    Thank you....Merci. ....

    Maybe I didn' explain properly......it' always ball 5 even when I start a new game. It plays all 4 players on ball 5 over and over......just like the show, the game never ends.

    Unless I shut it off or start a new game which just resets the scores to zero and then carries on at ball 5 and all 4 players.

    Hmmm, is the Player Unit in the head resetting to its zero position at game start?
    How about the Coin Unit in the cabinet?
    Basically, I would look for anything gummed-up on those steppers/ratchets and fix before chasing an electrical issue. Difficult to troubleshoot remotely without seeing what is actually happening...

    For the start-up sequence, this Mr.Pinball Target Alpha Startup Sequence should help you:

    Good luck!

    I haven't even had time to play over the holidays between family and overtime. I'm hoping to get back to semi-normal by next weekend and would love to have some help. Thank you....
