However, about the only difference in wiring with positive ground is the polarity at the battery, at the ammeter and at the distributor. | | | | | Joined: Apr 2009 Posts: 3 New Guy | | New Guy Joined: Apr 2009 Posts: 3 | how about gauges would it hurt to use them as a negative ground and also generator? thanks

The temp and oil pressure should be mechanical. I think the fuel gauge should work. I really don't see a need to change polarity of you are going to stay with 6 volt. | | | | | Joined: Apr 2009 Posts: 3 New Guy | | New Guy Joined: Apr 2009 Posts: 3 | not sure yet thinking might eventualy go 12v

The only reason you need to go the 12V route is because you intend to go with modern day electronics. Just a suggestion from someone who's been there. Cecil....... | | |
