No power to console gauge lights
Hey all- I've been troubleshooting why the lights won't come on in my tic toc tach cluster on my 1968 camaro. They've never worked for me. I went ahead and removed the cluster, and found both the clock wire and the secondary ground wires were broke. The gauge was still grounded via the strap ground at the top that connects to the high beam indicator light.
What I'm realizing now is that I have two issues. One, is the circuit board has a fried section just after the first lamp connected by the 12V pink wire from the harness. I'll obviously need to get a new circuit board asap.
The second issue worries me a lot more. At the fuse box, where the mini fuse is for the INST and LPS, there is no power to either side of that fuse. My test light doesn't go on when the lights are turned on or off. I'm not really sure where to go from here at this point. I have a wiring diagram, but I'm not sure I'm reading it correctly.
Also, labeled on the attached photo are two connection points labeled ?#1 and ?#2, these are currently not connected to anything. I'm not finding a reliable wiring diagram for the tic toc tach, so I'm not sure if those are grounds or missing connections?
I've read through the sticky which helped me diagnose the main concern here of no power going to the gauges from the fuse box. Any advice on how to proceed is much appreciated!
