I was checking out a 200amp alternator for my 1999 Suburban. I see prices
from $230 up to $750? What would be the difference? ie Ohio Generator &
H-O-alternator are in the $750 range; mralternator.com is $250. They're all
new, not refurbished, so why such a price difference?
I have a JL1000/1 and a JL450/4, which do ok at normal volumes - my stock
alt is 140amp, but when I crank it, especially relentless bass lines, the
headlights flicker a bit and you can see the volt gauge on the dash go down
a bit.
Another question - when I'm driving, even cranked it's ok...just when I'm at
idle does the voltage take a hit; will a HO alternator help that? Or will it
not make a difference at idle speeds anyway.
