son of 66 convertible, now owner
Dad gave me his 66 convertible V8 289. It was in storage for over twenty years, and rarely driven. But I am slowly restoring her back to health after all that deferred maintenance.
Last weekend, I installed a new instrument bezel, but forgot to disconnect the battery. A few sparks flew on the left side as I neared the end of the wire hookups. I disconnected, finished the install, replaced fuses, and reconnected the battery. Now the fuel gauge and panel lights don't work. (turn signals, high beam and other gauges work). The fuel gauge wasn't working properly before as once it reached half tank, it would not drop any further. Now, though, it just shows as full tank.
I did see on a similar theread that someone suggested checking the headlight switch, but my headlights all work as do the courtesy lights (not sure about the shifter light as it is burnt out).
As an aside, somehow around the same time, I blew the radio fuse, which was the 7.5 AMP fuse, not the 14 AMP fuse as shown in the manual.
Dad did some strange wiring, but I doubt he ever touched this stuff.
