Positive grounding

Post by forty-niner » Mon Dec 13th, 2010 2:50

I recently started work on a barn find that had been sitting for 10 years. I cleaned fuel up and got it running. Found out that this is a positive ground and it was hooked up negative ground when I found it. fuel gauge, ammater, and radio don't work. was wondering what the proper procedure to change back to a positive ground was.

Switching the battery cables should be enough ... you may need to re-polarize your regulator. Did they switch to 12 volts too or did they keep the 6 volt system?

Plus you need to consider that there may be need to replace / repair the various gauges. They may or may not have been damaged by the move to a negative ground.
