no voltage anywhere
I let my 2015 Savana 2500 sit for a couple of months, and went to start it a few days ago. I had no power, so I assumed a dead battery. I put a charger on it and waited about 24 hours. The charger says that it is fully charged. Everything is still dead. No starter, no lights, no radio, nothing. I don't have wiring diagram, so I'm not real sure where to look first. Any tips or advice???
