ground wire

  1. S40 & V40 (1995-2004)
    So I've recently picked up a 1997 V40 T4 Cd and I LOVE it. There is however an issue with the ground wire I've noticed. Sometimes it won't start and then cuts out like it has a dead battery but as soon as you poke the ground wire everything jumps back on. So I'm going to replace the wire myself...
