Does anyone have the schematic handy for a Gottlieb Mustang/Bronco? The front pop bumper on this one is weak, very weak. I’m showing less than 1 volt when it’s triggered. I’ve chased the red/green wire to the jones plug. No voltage on either side, to speak of. But I can’t find where the wire goes after that.

Thanks!

Thank you. Unfortunately, that doesn't seem to show where the red/green wire goes on the cabinet side of the jones plug. Those wires are pretty dirty and it is hard to figure which is what color.

It turned out to be a dirty switch in the relay stack.

Thank you very much.

Now to figure out how the drop targets go back together.

Thank you. I managed to figure it out after a couple of tries One last fix and it will be ready to play. I am working on fixing the worn contacts on the bonus disc.
