alternator problem

[Master]

well my snake only has 10,000 miles on it, i just bought a new battery but at low rpm "idle at a red light"
my battery light comes on until i take off.... low miles for a bad alternator i think?

Your new battery will be dead soon if you don't replace it. Put a 3.2 alt pulley on if you have a stock lower.

Was getting a new one at Ford since its under warranty... should i or should i get better?

get a stocker. just take your pulley off before you go into the dealer. I know the acc. are ran off a seperate belt but most dealers will look for any excuse to void your warranty. even though a smaller upper wouldnt cause your problem.
