Today I decided to replace some burned out bulbs in the dash, the oil light and left turn signal. I got those switched and decided to check my work before bolting it back in. Well the bulbs I changed worked but the lights for the fuel and ALT no longer do. I changed out the bulbs on those to but nothing. What couldhave happened? I even replaced the bulb socket, but nothing. Its a 67 Dart to be specific.
