Need help with my G-LOC Motor Driver Boards
« le: Mercredi 05 Décembre 2018, 09:27:25 am »
  • Hi

    I hope that some one is able to help me.

    My issue is that i have three defective G-LOC Motor Driver Boards / cages.
    I have one fully working cage but I need two.

    I have managed to get all the correct voltages present, but when I test them in my Sega g-loc deluxe there is no movement.
     (only movement if i mount the one powersupply that there is working)

    The last year i have tried to find out why but i have not been able to solve the issue, so therefor I reach out to you again in my last hope that some one can help me.



    I am willing to ship the cages and all my components for repair and also some money to that person who might be able to help me.  ^-^

    I have followed the super guide written by GC339 here https://www.gamoover.net/Forums/index.php?topic=28660.0

  • I have tried to follow GC339 (answer 10) here -> https://www.gamoover.net/Forums/index.php?topic=28406.msg453283#msg453283

    The above board I have changed the PC8 because it had a burned spot.


    I have also changed all the zener diodes ZD03->ZD11 (because when for two years ago when i successful repaired a driver cage the reason for the missing movement where some bad Zener diodes)

    but still no movement.....

  • An update more - I have uploaded an Excel file to dropbox and marked all the components green that i have changed.
    Components marked brown i have tested in circuit, and yellow the components i think is related to the logic movement part.

    See the tab "Repair log module 3" for all the parts that i have changed/tested on this board.

    Hopefully someone can guide me in the right direction in what i need to test/change in order to get the final movement part working

  • Hi

    YES YES YES - Finnaly!! (again) I now have movement!!   :-)= :-)= :-)=

    ITS ALIVE !!!  :-)=


    I have read CG339's guide over and over -> https://www.gamoover.net/Forums/index.php?topic=28406.msg453283#msg453283.. and finnaly i managed to put two and two together :)
    in this tread where he shows a diagram of the control logic, he mentions PC7,PC8,PC9 and PC10 as components who isolates the high voltage and low voltage...

    So i where thinking  ;).. maybe they are dead, and i did not know how to test them so i swaped them with some new




    So if you have all the correct volts, checked for burned traces.. but no movement then change
    PC7,PC8,PC9,PC10 then you have movement.

    I have updated my repair log on module 3 -> https://www.dropbox.com/s/cajy4szrq1bybzj/Nomenclature.ods?dl=0

  • If someone needs the service manual for adjusting the pontometers or greasing, then you can get a copy of my manual here:
