After getting mine rebuilt 3 times and still having the same problem, I ended up getting a Bosch factory rebuilt one. Cost-wise I don’t think it was significantly more than one rebuilt by a shonky auto electrician and in the long run would have been cheaper.
Mine was my alternator. Never had battery issues but once I replaced it with a new bosch all the electrical gremlins the car had went away.
Alternator wise, I'd definitely spend the money and acquire a nice Bosch unit to replace yours if you were gonna swap it.
What brand alternator did you use? If not OE, Bosch, or Valeo, change it again.
Step up and buy a Bosch. Yes, they do fail, but the odds are much less.
Bosch is still the gold standard but not what it used to be. Don't buy cheap junk.
B5/5.5 alternators come from two vendors, Bosch and Valeo. I've heard they're not interchangeable because of different pulleys.
Alternator. And unlike prior generations of Bosch alternators you can't replace just the regulator, which is usually what fails. Gotta buy the whole piece.
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.
I figured alternator, so took it to Autozone to scan and everything passed. Then took it to Meineke for them to check and they told me alternator was bad and replaced it. Well my interior lights were still flickering so I took it back and they say seems like the one they installed was defective, so they replace it again with an OEM Bosch and also print me a printout of a bulletin stating that under load lights may flicker and there is no solution.
