Battery and brake light on help!!

[mannyssj13]

My battery and brake light always comes on when driving at high rmps mostly or when just driving normal at random times. I don't do much highway driving so I never see this problem before so was doing 80 and my brake and battery light came on bright red normally it just comes in dim. My question is what do u guys think might be causing this problem? Here is a video of it don't mind the music in the back from haha any ideas will help out thanks!!

possible bad alt? on my car at least (not sure about 2gs) my abs light is a warning light. check your manual and see if you have one too.

Charging system issue. Likely a bad ground or inconsistent voltage from alternator. My lights were coming on like that just before my alternator puked. I would measure voltage at the back of the alternator, and then again at the battery. Should be putting out 14+ volts at idle in both places.

if you have a multimeter you can check it or take it to an auto parts store and they can hook it up and do a load test and that will tell you if any parts of your charging system need replaced

My abs light is on cause I messed up the sensor so it's not that.
