The instrument cluster illumination lights in my 69 Mustang have all stopped working. The gauges, turn signal, and hi-beam indicator lights work normally, but the lights the illuminate the gauges are out.
I replaced a couple of bulbs with new ones but still no light. Are they connected in series where if one is out, they will all be out until I replace the bad one?
Nothing was changed that would have made them stop working. A test light to the blue-red wire shows power getting to the connector at the printed circuit panel.
Does anyone know of an alternative 1/2" lamp socket that I can use to bypass the printed circuit?
