Alternator alternative 110Amp???
According to my research...the '03 V10 2v came with an alternator rated at 110Amp. Ok...NOT good enough IMO.
Does anyone know of a replacement for the smallish 110Amp alternator? Looking for a direct replacement with NO mods.
Thanks!

My '01's got a 130AMP. But I think they started to down-grade the ratings because when HOT they hardly put out anything near that.
There are upgrades, a new stator, rectifier bridge, and regulator, and they can put out 200AMPs.
What are you look for though? Idling charging ability?
Mostly, people looking for alternator upgrades are looking for better low-RPM power.
A smaller pulley can help that a lot.
Some of the "higher output" alternators don't put out any more at idle than the stockers.

YES...definitely interested in more idle amperage. Plus...I am planning on installing a WARN winch in the coming months.
Here is the deal...right now...according to my Tekonsha P3 brake controller my “Battery Voltage” is down. If I have the heater on 2nd or 3rd bar, radio at level 4 bar, headlights On (NOT high beams), and OEM fog lights On, then my P3 shows that I am only putting out 11-12.5 volts at about 2000 rpm.
That cannot be good right???
So...thinking that a 160 or 200Amp would do the trick. Plus adding the winch will add a serious drain to an already stressed electrical system.
Now...I have found several on eBay that sell the 200Amp version. Plus another (see link)...but the issue is not sure of the reliability factor from them.

That low voltage is NOT good. My '01 is rock steady at 13.5-14 no matter what I turn on.
With a winch, and the fact that it'll probably overload whatever alternator you put on there, I'd add a second battery with an isolator and run the winch off that extra battery. That way, you can run the battery down all the way and not kill the starting battery. What's the amperage of the winch?
Not sure about what to say about the 200 amp ones. I looked into that, and found that they are ALL rebuilds or at least, none of them actually come out and say "completely brand new".
I'd rather do it myself with upgraded parts, but ... that's just me.

I have a 9000# winch on my trailer and have towed up plenty of demo derby cars and busted trucks from racing with no problems from my stock battery or alt. It seems like you have a bad alt to begin with. If that is the case, then I would go with a bigger one if you can find a reliable source for one. One suggestion might be to look for one that goes on an ambulance/fire truck equiped truck. With all the stuff they have to run, they always go for the bigger alts and dual batteries.

Thanks for the comments!
I guess you confirmed what I suspected all along that my alternator has seen better days. I agree...it is time for a replacement.
I would do a rebuild (upgrade) myself, but have NO idea how. I did notice that NAPA had an alternator that was rated higher...so I may give them a chance...depending on there warranty.
Of course...it is now the coldest part of the year...but then again...that is the norm for these kinds of problems.
Thanks again...

...back in business...and ready for more snow!
You guys were correct...I had a bad alternator. It was the original...and lasted about 104,000 miles.
I went with an Autolite PRO-TECH found at my local CheckerAuto / O'Reilly Parts store.
Went with the OEM 110Amp version because I like krewats idea of adding a second battery w/isolator for the winch later down the road. The alternator install is SUPER easy...and only takes about 15-30min. That is going the extra...and using a torque wrench to specs on the bolts. With new alternator...the volts never dropped below 13.6v and goes up to 14.26v.
Thanks for all the responses...
