i have found out why the speedo dont work, the cable has melted on the headers it has bee routed from the auto box to the speedo right along side of them and the heat has washed it out.
i now have another problem, the lights etc, sometimes they work sometimes they dont. still has the old cotton braid wiring that is splitting and been repaired in places with bits of tape also my amp meter is showing low but the battery is working/starting fine. do you think i must have a short in the loom somewhere? might be best to replace the loom in case i get an electrical fire or something.
