I jump started the van and it ran for 20 minutes, After the 20 minutes I disconnected the negative wire from the battery and the van shutoff. I turned the van back on and disconnected the negative wire again and again the van shutoff. Now I knew this could be the alternator. So I changed the alternator and ran this test again and again the van shutoff.

I reinstalled the old alternator and tested and the reading was 13.98 volts which means the alternator is working properly.So I went back to the battery and disconnected the negative wire and the van shutoff.
