Alternator Bosch or OEM Mazda

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.

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.

I bought a Bosch rebuilt alternator from ECStuning and installed it last night. The light however has stayed on.

I bought a brand new, OEM Bosch alternator from Rock Auto. A week back I started noticing a bearing squeak sound in the engine on startup... Later got another battery light... Today was driving and lost power steering suddenly and got battery light again. Pulled over as the car was getting hot quickly. Opened the hood and the serpentine belt was shredded. Alternator was completely seized and had burnt belt on the pulley. Got it towed home.

I had a bosch alternator in my Mark 2.. 8valve motor. I noticed the battery was not being charged. so instead of dealing with the voltage regulator or brushes etc, b/c the unit was old I decided to go with a brand new one. making me think i should have ponied up to the Bosch.
