68 GTO Electical problems, Help?
I have a 68 GTO that is restored and ran perfect until yesterday afternoon. I went down the street to a grocery store, shut the car off. when I came back out It started right up no problem. I drove down the street aprox. 2 miles, parked, and shut it off again. Came back to it 3 minutes later went to start it and it was as if the battery had been 95% drained. It would only turn over about half a crank. I had no electronics on while the car was off and did not leave the headlights on. I had a tow truck come out with a portable jumper box and it started right up. the volts were only at 13.2. While the engine was running i disconected the battery cable and it stayed running meaning that the alternator was still good.
The battery that is in the car is no more than two months old and is the most expensive gel glass mat battery. I highly doubt the battery is bad.
Does anyone know what could possibly be the problem?
