Hey guys,

I currently have my 95 850 with a Bosch 100amp alternator which is on it's way out. Currently with no accessories on it charges at 13.1 volts and with headlights on, and my stereo (amp, sub etc) it barely charges at 12.3-12.6 volts. Amperage is down too.

I plan to change it myself, and there are two listings on ebay, one for a 100amp and for 10 bucks more one with 120amps., both remanufactured with no core exchange.

Can I put the 120amp alternator into the car with no ill effects?

As far as I am aware it just means that the higher the amperage, the more it can keep up with more demand, right?

Seeing as an alternator here at my local parts store is $760, I want to make sure I get the right one, as I'll be purchasing it online instead.

 

Unless you have added additional electrical accessories, the stock one is fine.

Yours is not charging because voltage is down (hence the current too) because it likely needs OH; most likely just the brushes, but could need more.

 

Yeah I do have added accessories, I have 2 amps, a subwoofer, additional driving lights, etc so that is why I am thinking of the 120 amp one.

Does anyone know if it fits in the same space?

 

You need to post a link to the Ebay listing or the part number for the 120 amp alternator to get an answer.

In your case with the "extras" you have the 120 amp would be a better choice if it fits.

That one should bolt right in. You might want to hang on to your serpentine belt pulley until you're able to match it up to the one that comes with the replacement. That or some don't come with a pulley and you need to use your old one.

 

You may want to also check the B+ cable going to the battery terminal. Many times the crimp goes bad and will cause a voltage drop. If the cable is very hot to the touch at the crimp, you may want to change it or measure voltage drop with a voltmeter
