    Good evening fellow pinhead. I have a DE Jurassic Park that lights up perfect everywhere except for the top and right side pop bumper. I have tried multiple bulbs. While in attract mode , the lights will dimly flicker but when starting a game only the left bumper light will light. I have run the light test and the two lights don't light. I have traced the two little black wires two the "junction" board where they connect with the other bumper lights and the wires are not broken and are still connected. Any suggestions on where to go next

    The sockets inside the pop bumper. Correct voltage to them ? Worn and not gripping light bulbs hard enough ?

    With a meter how would I test them? Blackhead where? Red lead where? What is meter set to?

    One lead on each side of socket.

    Quoted from maveric18:

    AC, if GI, should be 6 volts.

    The grip thing on the black lead is bent too far apart to grip the base of the bulb in the first picture.

    They also look dirty, might be hard to get an accurate reading.

    Looks like my 3 sitter target lamps aren't working either. According to the matrix the spitter targets and the two jet bumper lamps that are out are in the same column
