Probably only good for one or two tracks but I can confirm this works. I now have a working (broken) clock! But it could be used for more critical tracks. Basically a thin strip of aluminium foil folded for strength then hot glued on to good clean track on one side, fold over the plastic insertion piece and hot glued on the other away from where the connector block attaches. The plastic piece was cracked under the circuit board on mine I made up a new piece from a micro screw driver plastic box that I wasn't using any more and cut a right angled bit to size and hot glued that on to the dash as well which is why it looks a bit yellow between the tracks!
I'm not sure my soldering skills would be up to it. Maybe others have tried this? It's a very thin track, I'd be concerned I'd melt the plastic backing and warp it too badly. If I had the soldering skills I'l probably go down the hard wiring route like covkid did. I know syncroandy is developing a full dash solution, go westy have a replacement for a lot of money. Gap in the budget market there for the right person?
No need - it is conductive on both sides, well it is on the stuff I use. Haven't had any yet that isn't. I have used it for various jobs even electrically joining mini solar panels to make a larger one. You can use it to make the contact to the cell and then solder wires to it.
