multiple dash lights coming on

[moe95gst]

My brake, battery, and radiator light keep coming on.I have tested the battery and alternator.The bat. was fine and alt read 14.5 volts. The lights aren't on all the time but when they are on and I am running my amp when the bass hits they get brighter. Also the lights come on even when I am not running the amp. What should I do?

It's from low voltage, did you get the battery and the alternator LOAD tested? Or did you test them with a multimeter? Get them load tested.

Mine would come on and off occasionally cuz my bracket was loose it would bounce around in there sometimes charging sometimes not.
