Alternator Bosch or Mitsuboshi

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.**

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

If you were family or my customer I would get the Bosch.

IMO a rebuilt German Bosch unit is far superior to the Chinese alts.

I’m running my a 120amp Bosch but my car is m42 it’s honestly overkill for my setup with aftermarket speakers, amp, and sub.

I have replaced my alternator with a good "?" Bosch alternator and it charged for 3 days but now the battery light is on until the motor is above 2500 rpm

L300 4d56 engine - matagal masira nakakinis. ????

Pero on a serious note: alternator mabilis masira

supplier willing to give me a Bosch remanufactured alternator (as good faith) to compare. after installation on Bosch, the result is worse than the Denso (output at alternator at 12.5V)

Don\u2019t get a Bosch
