Engine Mechanical problem
1981 GMC Truck V8 Two Wheel Drive Automatic

I got an 81 stepside, when i got it i thought the battery or alternator was bad. I jumped the truck then disconnected the battery(+) from the terminal. The truck died. I got the alternator tested at 4 different places and it passed with flying colors. So i bought a new battery and repeated the process it worked this time with the battery disconnected. I tried it again and it didnt work. Whats going on?
