Hi Rick,

Yeah, looks like you were already on the right track with checking the instrument cluster. And you're right, those damaged traces leading to the indicator light sure do look like they could be the source of your short circuit.

A new replacement printed circuit might not be a bad idea (especially since they are available for most of these trucks). But in cases where replacements weren't readily available (or the damage was minimal), I have repaired some by soldering in sections of wire to bridge across damaged areas. You have to get the wire soldered into place fairly quickly and not keep the soldering iron on the trace for too long, otherwise it has a tendency to melt the plastic backing and make a mess. On yours, it looks like the traces are still intact (just pulled away from the backing & likely touching / shorting together). So you might be able to separate them and glue them back down without having to do any soldering.
