I drove my car home, ten minutes later it wouldn't start. It doesn't turn over, I get the click from the starter but the engine doesn't turn over. I thought it was the battery but anything that gets electric power in the vehicle toggles on and off along with the clicking (this includes if I turn on headlights, other accessories, etc..).
I checked the battery with a multimeter its at 12.5v when the car is off. I tried jumping the car and it worked...retested the battery and got 14.7 so the alternator is working and the battery is charging. I cleaned the battery leads and disconnected my aftermarket stereo as well as a precaution. All of my fuses are in good shape.
Any ideas? I'm considering a bad ground so I'm looking into checking all of my wires for corrosion and wear.
