Weird gauge cluster problem (lighting).
Wondering why I still don't have nice bright lights in my dash...
Here's what I have done so far:
Installed a new headlight switch, all new dash light bulbs, cleaning ALL of the contacts on the circuit board (both around the light bulb-holders themselves and the main plug-in to the cluster), cleaned contacts to the bulb-holders, checked continuity to all of the bulbs and circuits surrounding the bulb-holders, checked all of the grounds. Rheostat on light switch is turned "all the way" up. Everything A-Ok.
I despite all of this, I am only getting the far left bulb (in the cluster) and the far right bulb to light up. No voltage to the inner bulbs.
What am I missing?

Hi Guys,
i had the same problem with my circuit board in my 77-f-150. mine was out of shape and no matter how clean i got it, only two lights would come on. so i took the tailight assembly out of a 84 t-bird and replaced all of the dash lights, fitting them in snugly where the turn ins used to be. they fit pretty good so i hooked them up to the light switch, and now the dash lights up as new.i also put two more under the dash, for extra lighting.they havent failed me now for 6 months. its really nice now to see all of the dash panel in the darkness. i also put a universal turn signal switch on it, and got rid of the , sometimes it works, and sometimes it dont problem. so far so good.
