Alternator Bosch or AC DELCO

Well I definitely wouldn't have gone aftermarket but I understand you might have been in a pickle

As far as why it's not working at all, you need very good clean connections including good ground connections everywhere

ACDelco makes a brand new alternator for $95. They were the OEM for GM.

Bosch is a OE supplier to BMW - I would choose that over Valeo if it were a choice I needed to make.

I installed a new BOSCH alternator in my MERCEDES-BENZ 190E 2.0 1991, and unlike the old one, this one has a **D+ port, a B+ port 1, and a B+ port 2.**

I went with RockAuto as well, but went with the AC Delco Gold Reman that was wound to have 135 Amp output instead of the OEM standard (~110 I think) I want to say it was around ~$170 with a $45 core deposit. AC Delco is a solid name in parts, and I believe was reman'd in Mexico.

This is a known issue with non OEM and especially bosch alternators, the regulator gives a different signal to the power control unit.

Honestly, even the AC Delco quality is questionable.

The alternator went out on it, and I had to replace it four times due to faulty over the counter rebuilt Bosch parts.

Don\u2019t get a Bosch

I replaced the Alternator on my 2016 Mini Cooper Paceman with a brand new Bosch Alternator. For whatever reason the Alternator is only putting out 11-11.6 volts.
