78 crew cab electric issue

[ddc456]

Trying to diagnose why the gauges will not work in the truck. These are the factory gauges and none are working. Where should I Start in trying to diagnose the issue?

Thanks

Fuses. ​

Yes, fuses. If not, I’d check to make sure the cluster’s plugged in and my next suspect might be he printed circuit. Hopefully it’s the gauge fuse, and there aren’t any shorts.

I also concur that checking the cluster plug in and or the printed circuit sheet would most likely be your problem if none of your electrical controlled gauges are working.
