Singular Dash Light Not Working

[mulletmobile]

I will be pulling the cluster again to test it further, but I have one stubborn light for the RH side of the gauge cluster that refuses to work. The bulb was good, I even purposely moved bulbs around to make sure, cleaned the connections on the printed circuit main connection and at the bulb on the printed circuit. I used a wire brush, a little bit of alcohol and a pencil eraser and still nothing. Any thoughts on what may be causing this little bugger to not light up? I have to replace the one on the radio too, but I would like to wait until I have a better game plan for the cluster light. I did not move the bulb socket to a different location, maybe that is the reason or source of my frustration. Just wanted to check and see if anyone else has had the same issue or knows of a solution. Again, it is just on the one dang bulb and I do have the full gauge package on a 71 F-250.

Thanks in advance for any ideas or solutions!

The printed circuit boards can fail without leaving much indication to look for. You should be able to put a voltage meter on the copper ribbon at the light socket you're having issues with to test it though. Also ohming the bulb out to verify it doesn't have a weak filament.
Our trucks love...LED's similar to this one in the dash lights as they drop the current pull to nothing making the circuit board work easier.
I do not believe this is the right part number though, maybe someone will chime in here that has them in the dash:

Basketcase, thanks for the info. I may try and pull the unit once again tomorrow (if we get a break on the heat) and see what I can do with testing it.

Best to unhook the battery before you pull it out-then hook the battery back up to test.
There are too many wires in that area to short out causing more issues.
