Alternator Bosch or Duralast

So my just-installed today reman Bosch SR33X turns the light off with a very slight blip to 1200rpm.

I went with the cheaper Bosch unit myself for my M3, and it's been working well for the past 4k miles.

If the belt was melted to the alternator pulley, there was enough friction to melt the rubber. Simple answer, replace the alternator.

Also, my 90A Bosch alternator is about the same size and weight as my old 65A Bosch alternator. Going to a 90A alternator is a great cheap mod.

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.

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?

So I bought a new alternator off of Rock Auto that I was amazed that I had to re-use my old pulley? But when I went to put the pulley on, the nut stripped on the new alternator like instantly. The whole ordeal is trash

Good thing you got a Bosch instead of the duralast. I had a duralast alternator last about 2 weeks and when I was standing in line at AutoZone to return it and buy a real alternator, there was someone behind me also holding an alternator that lasted two weeks.
