Okay I'm workign on the neighbors manx buggy and they want to switch to a 12v system. I have a 12v generator layign around off of a 71 beetle, but I don't know if it is internally regulated or not, I believe that it is because looking at their generator it has a funky thing on the top that goes to the regulator that is mounted on the shroud next to it, and mine dosn't have that. And if it is internally regulated do I need to bypass the regulator on the engine? thanks.
PS the engine is out of a 65 beetle |

The 12 VW generator does NOT have an internal regulator - it's mounted separately under the back seat on the left side of the car.
Yes - the 6 regulator is mounted on top of the 6v generator.
The easiest way to change to the 12v generator is to mount the 12v regulator (30 amp type - DON'T get the 38amp bus generator regulator) on the fan shroud just above the regulator - that way you can just turn the 6v wires up to hook up to the 12v regulator - less wiring changes. The 6v wires are thicker than the 12v wires so they will handle the 12v just fine.
Go have a look at Speedy Jim's site

he has the full description for the conversion there.

| Yes the generator works, but it's not mine. I'm pretty positive though that it will be no problem. E-mail me at Keiran3@aol.com for more info and stuff. |

| okay I put the generator on and when the engine turns over it makes a loud high pitched sound, I think it's rubbing but on what I don't know. The generator in it now is out of a doghouse style fanshroud, but this engine isn't doghouse. Could that cause the rubbing? If so can I just switch fans? What else should I check? It ran fine before, in a doghouse, but it spent about 2-1/2 months in my barn. Thanks |

You can't put a doghouse fan into a non-doghouse shroud - it's too wide and will scrape.
You'll have to remove complete fan, backing plate and generator to change the fan for the slightly more narrow non-doghouse fan.
Also make sure the fan is centred along the shaft so it doesn't rub at the fan opening or the generator side of the shroud - there are 3-4 shims to move it fore-aft along the shaft. Put any un-needed shims under the wavy washer before you put the nut on (so the total stack of shims, washers and fan centre is the same length).
The nut takes 40 ftlbs - it's 36mm so you can use the same socket you use on the rear axle nuts.

Oh - and when putting the generator and backing plate back into the shroud, make sure the slot in the backing plate is pointing downwards - this causes cooling air for the generator to be pulled through the generator and into the fan shroud.
