Battery or alternator??????? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got in my truck to come home this morning and it would not start. All lights came on and did not seem dim. Left the light on and tried to crank it, lights went out, let off the switch and they came back on. Well got it jump started. I noticed on the drive home the volt guage would be at 13 while moving at about 45mph, but when I slowed down it would gradually go down towards the red line. And at a stop light it was just above the red line. Got it home, shut it off, tried to crank it back up and it turned over really slow and drained almost immediately. Is it the battery or alternator?
