Well about 2 days ago my brake light, battery light, and A/T light came on. It was really cold the night before. The truck started up fine but the radio would go off and on. then when i gave it a little gas, the lights would go off. then they would come back on when i let off the gas. So I went to autozone and they checked my battery. they said it was good but it had a low charge. they couldnt test my alternator at the time because the machine was broke. But today when i turned it off it wouldnt start back up and wouldnt go into neutral (automatic) to tow it. so WTF is the problem. Is it the alternator and why wont it go into N. thanks WOODY
