I was just curious, since the Haynes manual doesn't give an exact value on the alternator amperage, what is the amperage on a stock alternator in the 4th generations? I am going on 8 years on my stock alternator and never had any charging problems, yet ("knock-on-wood"). I know for the added "options", like the cold weather packages have a higher amperage, but what is the standard value for our Max's? Is it 120 amps or so? Any replies would be greatly appreciated.

 

I think they are 100 amp or 130 amp....

 

this is covered in the 4th Gen FAQ ...
