I am the original owner of a 1986 Golf Diesel and it is my daily driver. The key to my ignition became difficult to start the engine. I had to bear down hard on the key to start the starter. Battery went dead so I replaced it and jumped the starter wires and the starter turned freely. Small black wire from starter to ignition has no power, any suggestions would be appreciated. New to the forum, use to be faithful to the VW Diesel Forum but it has dissolved for no known reason. I was thinking about replacing the ignition but it looks to be quite involved and I hate to bark up the wrong tree.
