Alternator Bosch or Motorcraft

ran this one a bit in my 88 16v scirocco. works fine. a bit biger than the sotch as far as size.

A few hard lessons I learned: Have a voltmeter and ensure your battery is good, a bad battery will kill a good alternator (12.6V min on non running car) Find a reputable guy that rebuilds starters and alternators and try to get your alt rebuilt or find a new Bosch.

I would try replacing it with a stock Bosch alternator.

Got it. So am I correct in thinking that these Bosch alternators have both diodes to get to DC and voltage regulators to make it a clean voltage?

Welp... the alternator AND the battery are dead. New battery is in, now to do the alternator but I need food first. I was amazed that the store had a rebuilt Bosch alternator IN STOCK

My 05' Golf TDI came with a Bosch unit from the factory and lasted about 90k or so, I replaced it with a Bosch Reman and its been doing well, 120k now.

I got an OEM (Bosch) new replacement 120A alternator from German Auto Parts. It came with the pulley installed.

I ended up with a Bosch reman from AutoHausAZ .. was a bit cheaper than europarts-sd.

Yeah I just bought a bosch too and it was too wide also I had to hacksaw a mm off to get it to fit in my bracket.

non bosch reman alternators are the worst...they rarely last long, so you are having a typical experience changing them out all the time....lifetime warranty is nice with those cause they suck, period.
