Instrument cluster corroded circuitry

[Nez'sRanger]

I had my 1989 gauge cluster out a while back to convert it to led's... While it was out, I discovered that the copper circuitry on the plastic was seriously eroded/corroded on the back. I have several indicator lights that are fried because of this...
Does anybody know how to fix that other than buying another 30 year old unit at the scrap yard? Thanks!

It should be a simple fix. Wherever there's a break in the copper path, solder in a jumper wire. You should be able to use relatively small gauge wire too. The only worry I'd have would be if you can get solder to bond to the pathways.

If you fail at it, go get another one at the junkyard and either use it as-is, or carefully take it all apart and use the parts you need to repair yours.
