Maintenance/Repairs

I have a 1987 Chevy Bonaventure G30 5.7 TBI. Started with classic bad alternator signs. Dead batteries. Jump starts. After a jump start, the van will die eventually after removing the jumper cables. While the engine is running, disconnecting the battery positive terminal will immediately stop the engine. No difference in voltage on the battery with the engine running or not. Went out and bought a new alternator. Exact same problem with new alternator installed. Brought the old alternator to be tested. It tested good. Reinstalled the old alternator. Returned the new one. Research on the interwebs says the next thing to check is the fusable links. There were 3 14ish gauge ones and a much larger gauge one all near the driver’s side firewall. All four checked out 0.00 on the ohm meter. I’m stuck. I dint kbow what else to check. Any help?
