Kent | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | If you look at the wiring diagram, you will see that the headlight switch has a fuse. If that fuse blows it will cause the symptoms that you have described. | | | | | Joined: Apr 2005 Posts: 242 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 242 | Found the headlight fuse bad for starters what size fuse do I need to replace it. Can't read what was on the old fuse. Thanks!!!

It's not uncommon to get a short to ground inside the dimmer.

The insulation is starting to fall off after 75 years, replacing the complete wiring is not a job I am wanting to do. For now I am only going to replace what is causing the problem and I have checked out the cost of a complete harness from Jim Carter $600.00 WOW!!!! Thanks again for all your help.
