battery light

my battery light in my cluster lights up really lightly wen i’m driving on the freeway then wen i let off the gas it goes away and lites up again wen driving. what do you guys think could it be the battery or the alternator? thanks

Have your alt. checked, maybe voltage regulator on it’s way out, the white/blue lead at the alt. supplies the light with a ground if there is no output from the alt, the white/blue lead is also connected to the ICU so it is possible that the ICU is the problem, even the “ABS Control Unit”, [if you have ABS] as it is also connected to the white/blue.

First question I would ask is, is it triggered by speed, or RPM?:think: 94
