Replaced radio bulbs, now wont light
Replaced radio bulbs, now wont light
I had one bulb lighting the panel on the radio. I pulled the radio and soldered in 3 new bulbs to light the panel and now none of them light. I pulled it and put 12v to the bulbs one at a time and all light together each time. I traced the power 'in' wire(blue) and it has continuity to the bulbs. I tried to trace the other bulb pin out and it traces to an area on top of the board that has components covered with a clear rubber. cant see pass that, but I cant find continuity on any other wire coming off the board for the return circuit. Anyone got an idea what happened? clearly the soldering is good since they all light and can be traced with a ohm meter to other parts of the board. anyone have a wiring diagram and knows which wire is the return out?
