Porsche 928s The battery is fully charges and the fuses are okay. What could be wrong? I drove it out of my garage and parked it in my driveway for about 1 week. When I tried to start it to put it back in the garage it would not start. The lights do not work the radio does not work nothing works. It is a if the power from the battery is not going anywhere. The battery is fully charged and the fuses are okay.
