I have starting taking apart my vette for interior restoration. One of the 'little' things that didn't work was the interior lights. Courtesy lamps, gauges, shift indicator - nothing. Only the 'Fasten Seatbelt', 'Gen' and hi-beam ind. work. Today I took apart the entire center console and removed the gauge cluster. When I apply 12 vdc to the bulbs I can only get 2 of the lights or the other 3 lights but not all 5! I traced out the circuit and found that while all 5 bulbs have one lead in common (orange line, don't know if its supply or ground). The other side of the circuit connects 3 together and 2 together (green line). The link at the bottom is to a photo that traced over in paint. What connects the 'green' circuits to each other so that all of the lights come on?
