    Hi,
    Thanks for reading this post.
    A neighbour has asked me to try and repair her Williams Gulfstream, to be honest after opening it I feel a little out of my depth.
    I’ve read a few posts about the Gulfstream but can’t seem to find the specific issue I have.
    The problem is the game will not start and the solenoid that fires the ball into the launch are does not operate.
    • The coin device has been modified, I think it is somehow circumvented, can post photos.
    • I’ve checked the ball counter and it seem to move fine
    • All relays appear to work
    • The cam device also seems to move freely
    • When I press the start button the machine makes a lot of noise and appears to reset its self
    • The reed switch that the ball sits on before it fired into launch area does something (I can hear a relay)
    • There are no lights working at all
    • The only item that seems to be active is on the table “Special’ if you press this the ball will kick out
    • I have read that there is a lock relay, could this be at fault, does anybody know where this is located please
    Any help, advice, support or suggestions would be greatly appreciated.
    Thanks in anticipation

    I was reading through this link http://www.pinrepair.com/em/index3.htm and tested the lock relay, I think it's busted, 0 resistance.
    When I force it shut manually the lights come on but the flipper do no work.

    Should I ask a professional to take a look?

    The Lock relay does two basic things: When the game is first turned on, it fires the Game Over relay.
    Turns on the lights and power to the game when the left flipper button is pressed.
    The lock relay then remains on during the rest of the time the machine is turned on.
    If you are not blowing any fuses and the lights are coming on and staying on, the hold relay is good. If the lights won't stay on when you push the relay in and release it, the coil on the relay is bad.
    Look up the machine on www.ipdb.org. There are schematics and instruction manual there.
    The coin relay is what actually starts a game. The Outhole Relay fires the Ball Release coil.
    Is the outhole relay pulling in? If so, run a jumper wire from the yellow wire on the outhole switch that is the 4th fartherest from the coil, to the terminal on the ball release coil that DOES NOT have the RED wire attached. If the coil fires when you tap the jumper against the coil winding post, the coil is good.
    If the coil is good, bypass the fourth switch on the outhole relay and pull the outhole relay in. If the coil does fire, the switch needs cleaning/adjustment.
    If the coil does not fire, bypass switch 4A on the score motor and pull in the outhole relay. The coil should fire at once.
    If the coil does not fire, run a jumper wire from the blue/white wire on switch 4a of the score motor to the blue/white wire on the ball release coil. Drop the ball into the outhole. If the outhole coil fires, the Jones plug connection is probably bad. Unplug and replug the jones plug several times.
    If you did not understand these instructions, you should consult a professional, if you can find one.
    Good Luck

    Gulfstream was the first game I bought back in 1986, and it's the game I learned basic pinball circuitry, repair and maintenance. If it was me, I would take it to a pinball tech, unless you are willing to zip through a ton of hours chasing red herrings and pulling half of your head of hair out of your head. Worst thing you can do is start messing with things that aren't part of the problem.
    Most likely you have several issues in your startup sequence... there are several relays, score reels, and step up units involved in this circuit. Again, call a good tech is my advice.

    And maybe the tech is looking for an apprentice!
