I wrote yesterday about the horrible task of repairing the instrument cluster foil where it connects to the tach. I don't expect my repair to last, because there's just no good way to do it. But wait! It just occurred to me: All of those electrical connections ultimately come from the plug at the bottom of the cluster, right? Wouldn't it be easier and a cleaner repair to run wires from that plug to the tach plug? Yes, I believe there's some active circuitry in the instrument cluster. For those circuits, it wouldn't work to just bypass the foil altogether. But if the foil just carries the tach signals from the big plug to the tach plug, it'd work fine to bypass the foil. Furthermore, it may be more practical to fabricate an entire foil replacement of point-to-point wires laid up on a loom than to reproduce the original foil, as Jeff says the VW Classic Parts Center is trying to do. I'll have to find me a salvage cluster to experiment with. |
