Battery light

Electrical problem
1999 Mercury Tracer 4 cyl Two Wheel Drive Automatic 120000 miles

My battery light comes on when the engine rpm's increase above idle. At idle, the light is out and there seems to be no problem.

My first thought is the alternator, but why would it be alright at idle and only have a problem when i step on the gas?
