    e-brake light & battery light on

    Hey guys my emergency brake and my battery light on my dash keep spuratically coming on and off.. my e brake light stayed on for a while even after my brake was unlocked.. battery light seems to flicker .. could this be 1. Bad battery 2. Bad alternator or 3. A bad ground? .. I have hids installed , memphis door speakers and a subwoofer.. along with a couple gauges.. battery looks like its showing its age.. any ideas? Ill have a battery test and alternator test done tomorrow.. just curious if anyone else has had this problem

    Battery light is almost definitely a bad alternator or battery. Report back when you get them tested.

    Brake light is likely due to low brake fluid. Check your resevoir, fill if needed and check again.

    Battery and brake on simultaneously as you described is likely a charging system issue. Check the brakes as a matter of principle but be prepared to troubleshoot an electrical problem, likely an alternator. The short answer to all three of your questions is "yes."

    Alternator checked out fine as well as battery .. it stays off now for the most part till I hit full boost then they pop on .. im going to re wire my grounds tomorrow but if that don't work then I have no idea where to go from there

    Bumping this .. resecured grounds today.. e brake and battery light still pop on simutaneously under high boost.. otherwise when im driving like a granny no problem .. soon as throttle is released they normally disappear ...

    Who checked the alt? At WOT the alt has a pretty big load on it. Unless you have a volt gauge or way to datalog the car it's not going to be easy to further diagnose.
