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

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

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

Turns out q68 transistor was the problem
