I have no lights working on my dash gauge panel with exception to the GEN light. The rest of the lights, turn signals, headlights and brake lights are working. I have considered that it might be associated to the headlight switch, but I would like to eliminate all other possible sources before I invest in a new switch. Yes, I have twisted the headlight knob, no change. Dash wiring is currently grounded to the lower left edge/lip of the dash. It's making me mental!
