Alternator Bosch or AC DELCO

There is a Bosch unit that will fit with the same connectors, but the pulley is usually different. I went to a local auto electric shop and they asked about the current I wanted at what revs and they built a Bosch unit with the appropriate coils and fitted my old pulley. Plug and play, and it's been flawless for 10 years or more.

90 amp Bosch alternator I'm using for my 8V motor. I upgraded the +12V wires to 4AWG from the alternator to the starter and the starter to the battery. Make sure your grounds are good. Battery to frame and to motor. And alternator to motor.

Have a look at Rockauto.com

They have Bosch remans in different sizes.

If you go for a bigger output alt, add a fat cable between the output and the battery via the starter terminal, as the two wires that carry current to the battery via the starter terminal will then be undersized. The cable cost is minimal.

Buy the Bosch it's a direct OEM REPLACEMENT alternator it's probably still going to need programmed via vcds to allow the computer to adapt to the voltage change of the new alternator

In your case I would say just buy a new replacement alt from a name brand like Delco Remy or Bosch, none of this parts store rebuilt junk, you'll just be doing the job over again soon.

Bosch, Valeo, or Denso would be my top choices. Don't get a Chinese one. Shit won't last at all.

IMHO this is not going to work. The brushes and slide rings lifespans are about the same so IMHO you must replace whole set if you expect this to be a permanent fix. Also, you have to clean the housing from old copper dust and graphite.

Looks very similar to a Porsche 944 alternator.

I got an ACDelco reman alternator from RockAuto, but it has a grinding feeling and bearing noise when I spin the shaft by hand. I'm not putting that "reman" alternator in the car only to have it fail a few weeks from now.

ACDELCO because if I get another API alternator that’s defective I’m going to kill somebody
