I rewired the dash on my 1961 Sabre to get wire colors correct and upgrade the old wiring, but now the gauges lights don't work. I have a strong new battery and power is correct to the light switch, which is a 3-position, push-pull type. I tested with a test light and a DMM. But no lights on any gauge or nav lights with key on and light switch fully pulled out. I put a brand new bulb into one socket, and still no luck. Fuses are in good shape, and engine cranks, so no breaker issues. The neutral safety switch works, but the switch light does not illuminate with the key on and trans in neutral. Any ideas?
