  • Battery gauge jumps/low

    Took my car to work for the first time since all the mods happened.

    My battery gauge is either low or jumps around at times.

    Brand new battery about 100 miles ago. Runs fine but is my alt going?
    This is as low as it would go. My last battery that I had would always be up near 18.

      Yup, sounds like the alternator is taking a dive.

        Check your battery terminal connections make sure their tight. Check your grd connection on fender well.

                    I got a readout of the BCM that controls the lights, Im going to just start cutting wires one day.



                    I have gotten so used to the lights that they dont even bother me anymore.


                    I just pay I make it home in the car.
