Just wanted to tell everyone that I finally fixed the dash light's in my 76 Nova. I tore the whole dash apart, replaced all the burned bulbs, rewired the loose wire's on the tach. I also discovered after I had the dash out and dropped the steering column down, that a wire was pinched between the steering column bolts . I fixed the wire, now all the dash light.s work perfect!!!!!!!I have been trying to fix this problem for a long time YEE HAW!!!!!!! thanks to everyone for their help especially Streets.
