Alternator Bosch or OEM Mazda

Just did this mod today and my voltage went up to 14.4v at the battery/alternator!!!! Wahooooo!!! And by the way...the car drives sooooooo much better!!! NIGHT AND DAYYY DIFFERENCE!!! I'm glad you posted this up...i never knew!! Cheap $1.50 mod and it actually WORKS!

buy a brand new Bosch one....the aftermarket ones suck, ask me how I know....this is one of the few areas where buying the original bosch oem part makes a huge difference...they are usually around 30 dollars and should be lasting you at least 2-3 years

you should be able to find bosch for way under 300 don't get anything elkse unless you trust it. I had 2 no namers fail within 6 months. bosch is going over 2 years now.

Multi rib surpentine belt. self tensioning alternator only three pullies crank, wpump and alt. No tensioning pulley etc. bracket pn: 028 903 143 AD alternator: Bosch AL0185X Then there is a big spring that goes between the alt and the bracket to tension it all. sweet piece.

i had a bosch 75 amp alternator on my beetle, w/ a huge amp wired up and it was great... never had problems w/ it...

I called IPD, a Volvo specialist here in Portland, and they sold me a direct fit, adjustable voltage regulator for my bosch alternator, now i have the voltage output set at 15.5 volts when the car is running, and yes, it helps immensely. no more slightly undercharged batteries.

My newly remanufactured Bosch 120amp alternator was extremely hot last night on the end of a 500 mile trip. Alt light never came on, all electricals were good, but there was a burning smell form the vents that seemed to be coming form the alternator's location in the engine bay. I touched the casing and it was very hot. Now this morning the battery is stone cold dead.
