Got an issue with my Gottlieb Genesis. The #3 light by the drop targets no longer works. Worked before we cleaned and waxed the playfield. We changed every light bulb top and bottom just to make sure we had good bulbs. Wire looks soldered to the contact good and the ground is soldered good as well... Don't look like any cold solder joints. When i have all the lights on before starting a game I can make a connection with a different light bulbs wire and it comes on. So seems to me like there isn't power getting to the bulb where the wire is soldered on. Any help will be appreciated. I'm at work tonight and won't be able to do anything suggested right away.
