Just went to start my car and there's absolutely no power. Nothing. No lights, nothing. My 12v battery was replaced six months ago. Earlier today when driving to lunch I notice for a few seconds when when I went to accelerate it wouldn't. The RPMs went up but it didn't have much power. The red triangle light went on and the "problem" flashed on the display for a second. I drove about ten miles afterword with no problem. Parked the car and for a few hours and now it won't start. Any ideas on this?
Start by testing the 12v battery with a voltmeter at the jump points under the hood, and again at the 12v battery in the truck.
