Convert 36hp motor to 12V?
lowrider - December 10th, 2003 at 01:39 PM

Hi all,
can anyone advise an easy way to convert the 6v genny to a 12v one. Is a re-wind the only way?

a later 12v one won't fit the fixed pedestal ...

thanks
Andy

Yes the only way is to re wind a 6Volt genny into a 12V output.

there is one other way if you can find a 90mm dia genny from an early Porsche.... but there like rocking horse shit and about 20 times the price.

I would be interetsed to know if you do happen to find an Auto Electrician or perhaps a Motor rewinder or reconditioner who is willing to rewind your generator.

I know this used to be pretty common with alkl the 6 volt VWs getting around but its died off nowdays.

I had a 6V / 12V rewind genny a few yearsago 1976 to 1979 used to run good.

I'm using a brand new Brazilian 14v 38amp generator which is the same size as an original 6v gen. Not too sure where you buy them, I had to swap an old floorpan for it :D

yep i think thats the problem they have all dried up... n gone west none left

I would like 2 of them to convert my 56 and 65 restos to 12V... bloody 6V batteries area pain in the arse.

I could swap batteries from any of the cars and always have one charged ready to go.

to spare??

Ive ask a few auto Electrical people here in Sydney but they all say they aint got the time or effort.

I suggest you look around at some of the older established Auto Elects up around yr way maybe they have the experience.

Guys
I know this is rather exxie, but on my old Elfin F-Vee, I simply added a 12v regulator to the 6v gennie.

It results in a very dirty, noisy output waveform but if you not too worried about noise in the radio the generator worked just fine like that:D.

The gennie light will not go completely out under about 2000rpm.

Shitty sad fix but works well enough to get you going.

Interesting

I know that the 12V genny has more windings in it than the 6V thats have the problem trying to stuff more copper wire in the guts of the genny
