FWD: Need Help with 12v Gen for 36 hp type 1
Scott Fraser
out in RAMVA somewhere. Please hit reply to Felipe (as well as the group) as
I'm not sure if he reads ramva.

Note to Felipe,
You should point your news reader to
news:rec.autos.makers.vw.aircooled for a treasure trove of answer persons.

is quite dissimilar. However, I remember hearing through the grapevine that
a Porsche 356 12V generator has the same size and shape as our old 6V
ones... Although Joe Locicero would probably be the one to
validate/eradicate what I just said :-)
I *think* also that Kymco has some special generator made up for this
purpose.
Also, Scott, you forgot to give Felipe's address... so I didn't send this to
him. Sorry :-)
Take care,
Shad

You heard right, BUT it is an expensive piece of kit !!

Check with Stoddard or Tweeks for just the field coils and the regulator
and have an auto electric guy switch the fields. The screws holding the
iron to the case are really tight. Even a used or dead 12V small Gen of
this type usually has good field windings.

but you may not find these they are somewhat rare. On 1966-1967 912's they
were standard and are more likely to find. Figure on about $200-250
depending on if you have an exchange which of course you will not if you are
trying to exchange a VW 6v core. I have one on my 58 Ghia and have been
quite satisfied, very stealth the only thing that gives it away is the
regulator needs to be mounted some where other than the generator. Of
course 6v generators can be rewound also to provide 12v some Porsche shops
can do this.

pretty easy.
To remove the screws it needed a punch screwdriver.
The rotating part can remain the same?
Do you know if a 12volts need half or double number of wire turns?

You need to double the (current)*(No of windings) product of the armature
windings, in order to double the generator's output voltage at a given rpm.
This means you can either keep the same field current and double the number
of windings, or double the current to the windings. It's not as simple as it
seems: Doubling the number of windings will change the resistance of the
windings and alter the current. Doubling the current can exceed the nominal
current and burn the windings. Also the converted generator must cooperate
properly with the regulator. You must know very well what you are doing to
do this yourself, and you must be able to take measurements and adjust the
number of windings properly.
I'd suggest that you disassemble a 12V type I generator and get the
windings from there. I don't know if they will fit, but I believe it is
possible. This has more chances to work.
