STILL USING UP BATTERY?

2002 Ford Focus • 100,000 miles

Battery light came on steady, car died. Shop said needed alternator, replaced it belt good, tight. Battery light comes on at redlights, stop signs, at idle. Cleaned terminals. Battery is 1 year old. Drive to work, car wont start until sitting all day. New alternator didnt fix problem but cost alot. Any help will be greatly appreciated.

I would check for corrosion/high resistance on the alternator-to-battery cable. A voltage drop test would be the best way to determine this. Any reading of.2vdc or higher would indicate high resistance.
