Hello everyone.  Im new here and Im hoping someone can shed some light on my van.  Its a 94 g20 with a 5.7 liter.  It has a new battery.  Something is draining my battery in 10 minutes flat.  Ive pulled all the fuses and the cpu and it still does it.  It does this with no key in the ignition.  I just tested the battery voltage.  Its at 13.2v.  I have 12.4v going into the bunch of wires that come off of the cable that goes to the battery.  These all connect together on the firewall behind the battery.  I also have .4v going to the starter.  All with the key off.  Am I overlooking something simple?  That group of wires going to the firewall, where do these branch off to?  Im not very good at troubleshooting and I dont have a wiring schematic for my van.  Where do I start?
