6V to 12V conversion advice, bitte

[1963]

Hello all! I haven't been here for a while (I've actually been doing work!)

My old lady's '63 Beetle has been a nightmare recently - new battery draining virtually weekly, hardly visible indicator & brake lights, windscreen wipers that bring the car to a stop. Trouble is, I'm in CT and she's in JHB, So I reluctantly decided to convert to 12V for her safety (keeping the original parts, of course!)

Trouble is, she also whipped the car off to a mechanic who doesn't really have much experience of VWs. Long story short, he's had the car for 6 months and says he can't get hold of a part. He sent me this from, I think, a Haines manual ...

Generator:
'1200A' Bosch (6-volt) ........................................111/903/021H
Alternative VW (6-volt) ....................................111/903/021J
'1300' and '1500' (12-volt) Bosch .......................... G(L) 14V/30A/20

All of which is Greek without reading it in context. Can anyone explain what I should be looking for, maybe advise where to find one in CT, any alternatives or better ideas (shouldn't we be moving from a gennie to an alternator anyway?)

Any help greatly appreciated. Vielen Dank! as they say in Wolfsburg.

Buy a new 12V alternator from Calooker and all your problems will be solved

Lekker, thanks Pine. That'll fit OK, will it? I'll PM Calooker now.

Ask him about an alternator stand as well (if you mechanic hasn't found one yet)

I would also investigate the wireing,making sure it can handle the increased amps with out burning.

higher voltage means lower amps
