Trouble starting and battery light on in dash
I just had a new head unit installed and I was curious if that could be causing the batter/electrical problems.
Whenever I do eventually get the car to start, the radio will turn on and when I put anymore of a load on the system, like lowering the windows, or lights, or defrost, the head unit will turn off and it seems like the car is going to give out.
The lights seemed extremely dim the other night and even the check battery light seemed to fade in and out with my decelerations and accelerations.
Before the new head unit, the battery did have problems going flat occasionally, put it almost always started and never had electrical problems.
Alternator? Voltage regulator?
