UPDATE:

After cleaning my alternator, I took it to be bench tested. Good news is it tested fine (14.7?). I also tested the battery, which is also fine. So I tried to jump the van and drive it to get a diagnostic done...

The van will start with a jump start, but if the jumper cables are disconnected, the van immediately dies. Dash light that remain on 1) Charge Engine 2) radiator

Now what? Am I missing something. Any help would be great...
