Dash Lights

[70spider]

Well my dash lights were a bit dim and the right side on both the speedo and tac were out. I replaced all four bulbs in the speedo and tac, noting that the ones that were out before were burnt up. So with this I was hopefull that all four would work, nope, the two that were out are still out. It looks like I have to remove the gauge cluster again and see if the socket is good. My thought is could this be a ground problem? If so where is the ground for the circuit located? It is not that big a deal due to the bulbs I got from AR are bright enough to light up the speedo good enough to read 70mph and the tac to 5k rpm, it is just I am a stickler for wanting all my electrics to work.
Thanks Pesto.

I think all the gauges use the same ground wire. I just added an extra wire in the middle and connected it to a good ground, it made a lot of difference. You may have contact issues with the sockets that are not working.
