Someone said I need two of these one for the fuel guage and one for the

reverse polarity. I am going to a 12v. negative ground setup.
Thanks Terry Clark

Terry just adding a bit more to the discussion. There are many variations to the theme re the solution to suit your particular requirements. In our particular situation with the Chev. Aust. No.6. Artillery Tractor I decided to change to 12V.
A couple of things influenced the decision. First there was no wiring to speak of in the first place. Second we have a restored Canadian built (Otis) 40mm Bofors which is to be towed by said tractor. It is registered on the road and as such we need a boat board on the rear to travel from A to B. Everything except the starter motor and the fuel electrics were changed to 12VDC. The 6V generator was replaced by a refurbished 12v version. The starter motor is a 6VDC original but no problems running it on 12 which only left the electrics for the 2 fuel tanks with the single gauge and selector switch. A 12VDC to 6VDC converter was installed just for the fuel gauge electrics and the whole system including the necessaries for the towing aspect works very well. A couple of images of the wiring upgrade attached. Wire came from Vinwire in Melbourne. Rod
