So my car will never hold a charge overnight. Every morning I have roll start in the the parking garage. I went and had diagnostics run on the battery and they said it's good.
Now my head unit won't turn on either so I'm thinking that could be the cause of my problems. And advice on what I should do? I was gonna rip out the unit to check connections but I would be very surprised if one was bad. I have an aftermarket Kenwood xdc-794 head unit and a boss subwoofer.
