Okay so here is what is going on... I was driving my ex girlfriend home last night and she told me that the brake light as well as the battery light just turned on, so i made sure the ebrake was completely down and it was. We get to her house and I drop her off and get back into the car. It started right up with no problem so I drove home. After a bit of driving i begin the realize the dash lights were beginning to get dimmer as i am driving. Then as i turn onto my street the ABS light pops on. I get into my driveway and put the car in park and then the revs begin to increase abnormally to a little over 1 which never happens. So the brake, ABS, and battery light is on and i turn off the car. I am somewhat sure that all this is happening because of a dead battery but I just want to make sure that the battery is the only thing that caused all this to happen.
