Hello everyone while I had my circuit board for the instrument cluster on my bench, ( cleaning contacts) I noticed a dig in the copper etch going from the connector socket to the fuel gauge. ( the dig is about an inch away from the connector ) Something must have dropped on it at some point. My ohmmeter does show continuity from the socket pin to the fuel gauge terminal so the etch is not broken. Should I be over cautious even though this connection still shows continuity but some of the etch may be broken? Ive seen that this copper etch can be soldered. I am a electronics tech by trade so I could do it. Is their that much voltage on the board or should I leave it be? Thanks
 
Depending on which circuit, either 12 volt or pulsed voltage off the limiter. I'd solder it. I've even soldered jumper wires on broken circuits.

I second what DVW said. This is a bear to remove after finding that it didn't work after you installed it. A little solder now will give you piece of mind.
 
Soldering a short jumper wire across the "bad" spot would be good insurance and won't hurt a thing.

Only low voltage (+5V average) to the fuel gauge and then the ground trace to the sender (which is what it sounds like is damaged here) on those boards. Very simple electrical circuits on these cars.
 
At the end of the day a new board is a solid investment I did the old solder thing on my original board because of a blown trace, sure it fixed it but then the pins all got loose, so soldered those up like a reinforcement but then it looked like crap. You're a tech like me then you know in the end a quick fix like that will work but knowing you have it rigged up vs just replacing it and not having to worry about it again is so much better.

Plus the solid state V.R. was a no-brainer for me.
