    Hi Everyone,
    I have bought a Data East Jurassic Park. It isn't working.The main problem is from the power supply. I have replaced the connectors and fixed the 5V circuit but i can't fix the voltage to work the display .
    There is 90V AC from the transformer but there is no 100V AC

    I checked the connector from the transformer and to my surprise the black /red wire of 100 V AC, is missing . I have posted some images of the transformer and the connector to show the problem.
    The Jurassic Park manual shows the diagram with the black red wire.

    Its making me crazy, because I don't understand how to find the voltage of 100 V AC to work the display.
    Can anyone help to resolve this problem? All advice /thoughts welcome!!
    Many thanks in advance!

    Are the jumpers set correctly for your country?
