My dash lights are brighter on the speedo side than they are on the idiot/gas gauge side.I've changed bulbs but nothing.If there was a socket not plugged in...say the generator socket or any other socket would that be the cause?
Check to make sure the sockets are grounding properly. I had the same problem in my 69, the speedo was bright, but the other side was too dim to see in the dark. After replacing the bulbs a couple times with no effect, I checked to make sure the ground was making contact, basically crawl under and look up under the dash and plug in the socket with the lights on, see if it lights up. I found out two of the sockets weren't making contact, a touch of sandpaper on the surface was all it took to get a good ground.
