Alternator Bosch or OEM Volkswagen

I did this on my mk1, along with a 90A Bosch alternator (AL49X ?) and a variable voltage regulator to get 14V. Also, I replaced all the tail lights and side markers bulbs with LED bulbs (superbrightleds) . This greatly reduced the amps drawn from the alternator.

I just replaced mine last week! I bought a remanufactured Bosch from FCPEuro. Looked brand new. Also was a pretty easy DIY.

Bosch is the OE manufacturer for motorcraft alternators so if you find a Bosch chealt cheaper, go for it. They're the same minus the motorcraft sticker.

That Bosch VR6 alternator was not a direct fit, but significantly easier than the Delcos other Rover owners commonly used. My method was faster, cheaper and way more reliable.

Get a Bosch or Denso alternator. I'd buy used before one of those brands. Just my preference, I know they sell tons of starters and alternators, but I don't like to do things twice.

Update: There was a direct short in the alternator and when it shorted internally it also took out the 200 amp protection fuse ($115) too for the battery. I got a new Bosch unit and I was happy to find out I did not have to bring it to the nearest dealership and that a local German repair shop were able to do it.

I wasn't crazy with the AC Delco (GM) alternator conversion when I used it on my MGB engine. The Bosch ones seemed to be a little better designed and easier to convert, plus they looked simmilar to the Lucas ones.

Bosch rebuilt alternators are like $175 online. Lots of people experienced low quality rebuilts. Have people had good luck with Bosch rebuilts?

We have been having a lot of trouble with Bosch reman alternators and starters in the last couple years. Pretty sad, used to be great stuff. Now all the boxes say made in china and everything is crap.

Upon only 3 days of ownership, the alternator went out due to the battery going bad, that took out the internal voltage regulator.
