All my electrical woes.

I figured you or 67Dart273 would offer to help. I wish you lived next door! The radio is low priority right now as it does work. That's one I can work on over time. The tach wire that I pinched and started all my other issues :violent1: runs from the the fuse box to the bottom of the tach, with a black wire running from the top of the tach to the coil. It did appear to be newer wiring so I am wondering if the car didn't have the rallye dash originally and the guy before me installed it.

Is the voltage limiter something that can be changed or tested or would I have to replace the gas gauge? And can that be done, or would I have to get the whole instrument cluster? Where would you look for a problem? The instruments just died a day or so ago, the fan was a week or so back. But have had my hands up there so probably messed something up. But looking I cannot see anything obvious pulled off.
