65 Barracuda gauge problems

Before you fix it, make sure it is really broken. Use an ohmeter from that pin to the Vreg terminal. It looks like the copper trace just lifted a bit, maybe from heat, but is still intact. These circuit boards are amazingly simple to follow and repair. Anybody that understands V=IR can understand one. You should see what people deal with at companies where I have worked, with tiny surface mount chips and traces you can barely see (like on a PC motherboard).
