6 Volt Pos To 6 Volt Neg

NYVines · Apr 25, 2012

How can I convert my 6 volt positive ground to 6 volt negative ground... is it simply a matter of switching the wire that goes from the distributor to the black box and also changing the cables on the battery to neg side ground??

Also... can i use a readily available 12 Volt cable from the battery to the starter?

This is on a 1956 cub lo-boy

Thanks

And switching the ammeter wires, and polarizing the generator. Anyway, why? The tractor doesn't care. But, if your voltage regulator says 6 volt positive ground on the bottom it won't last as long. No such thing as a 12 volt cable -- but the bigger the diameter of the cable the less problems you will have. I use 2 gauge. Many people say you need 0 or 00, I see no need for ones that big.

Thanks for the info, I am going to leave it neg ground. I was concerned about someone jumping it and hooking it up backward

Jumping would be the same either way. Pos to pos, neg to neg. It was originally set up as negative ground, leave it that way. A cable sized for 12 volt is not big enough to carry the juice. A six volt system requires the larger cable.

Only one way to jump start something and you have to hook + to + and - to- or all you get is sparks and more sparks. Also if you jump it with a 12 volt battery you should never hook the 12 volt battery to the 6 volt battery or it maybe the last thing you ever see again. 6 volt battery's like to blow up in your face if you hook them to a 12 volt battery

At 6 volts, I would recommend having it as built, 6 volt positive ground. There is no advantage to changing it to 6 volt negative ground. If you make it 12 volt, then go 12 volt negative ground. #4 cables are ok for 12 volt but are not big enough for 6 volt.

Why change your voltage regulator will fail cause its probably for positive gnd. Use 1ga cables.

This is a Cub we're talking about 4ga wires are plenty fine.

Why change the ground??

As for the battery cable, the answer is no.

For the higher voltage (12v) there's less current flowing to the starter, so you don't need a very heavy a battery cable.

For a 6 volt battery, there's more current so you want the heaviest battery cable you can get on there to keep from restricting the flow.

It would probably work just fine while all your connections are fresh and clean, but over time you'd eventually be sorry you used a lighter guage cable.
