2002 Forester S Premium 4EAT
While shopping for a new alternator today I found out that there are a few "different" alternators that will fit my 2.5 SOHC- the difference being the charging capacity, I'm wondering if anyone has any idea how Subaru determines how much charging capacity each model gets. My '02 Forester has a 70-amp alternator, while my dad's 2000 Legacy with the same 2.5 SOHC engine has a 90-amp one. I've got heated seats, fog lights, heated mirrors, and heated windshield as part of the cold weather package. My dad's Legacy has none of the above. Can anyone come up with a reasonable explanation for why the Forester gets less charging power? Doesn't make much sense to me.
