PONTIAC GRAND PRIX BATTERY PROBLEM

2009 Pontiac Grand Prix • 80,000 miles

2009 grand prix won't start, just clicks when the key is turned. Charged battey overnight and same result. Replaced battery and worked fine for a few days but now it's the same problem. I put a voltmeter on the battery with the car running and it shows 14.6v. With the car off it's reading 12.5v but still won't start. What else can I check?

Sounds like a dead spot in the starter motor. Tap on it with a hammer to see if it will start
