Whats involved in a generator to alternator conversion??

The generator is already 12V.

They have inbuilt regulators don't they?

use the same stand? Generator fan fits just the same...? same belt? differences? Same wiring?

Thanks fellas!

some (usuall aftermarket, I think) have internal regs, some don't. Physical differences: you will need to change/replace the genny stand and - possibly - the fuel pump.

Good idea to double check the specs and condition of your fan while you are there, too

it was the 74-some 75 ones that were ext regulated
75-76 and all aftermarket ones are internal now

with how cheap there getting its got me stuffed why people are still out there driving on generators
a nice original rarely driven stocker yea but a daily driver??

Hiya Sean,

That is, by far and away, the single best illustrated write-up on generator/alternator conversion I have seen. Matter of fact, it just might be the best illustrated write-up (on any VW related subject) I have ever seen.

Awesome my friend!

A Generator stand is different to an alternator stand Chris...

an alternator fan belt is a different size . 11.3 x 912mm

You could grind a Generator stand to fit an alternator..
very easy if you had both sitting side by side...

If the alternator only has two connections...
[internal regulator]

a screw connection - main power to the battery..
and a push on connector which goes to the dash lamp...

cheers

PS: the alternator is earthed thru the stand and strap etc...

Mike,
No worries. Although I have to keep my slightly befuddled brain in gear to update that post with some additional info.

Lee,
Isn't the OG stand made out of mag alloy?? Bonfire time whipping out a grinder on to it if it is:lol: .

Regards
Sean

If you can find a good origional bosch alternator
it would be better than the cheap CHINESE versions available nowdays
