I when out to start my Truck this morning, and it would not start. Battery was dead. I jump started it, and as long as the Jumper cables were still on the battery in the truck it stayed running. When I took the Jumper cables off it died. I restarted the Truck and the wife, gave it a little more gas as I removed the jumper cable, and it still died. I figure its got to be the alternator thats needs to be replaced. What would you look at? Thanks.

I'd use a digital multimeter and do some testing. With the meter leads across the battery posts, 12.6 volts is a generic spec for full charge. If the battery is down, take it off and get it charged. Make sure all battery connections are good. Then, with engine running, take a second reading across the battery posts. The second reading should be higher than the first, if the charging system is working.
