Wiring Diagram






Above is the current wiring diagram I have in the van.  I recently had issues where battery C died, dragging down the system.  I used a battery checker - a little clear plastic device with a floater in it.  Battery C showed as weak while battery D showed as good (despite only measuring 7 volts when isolated from the system).  So battery C appears to have died and dragged down battery D's charge with it.  I took battery C home, replaced the fluid with fresh distilled water, and it charged up properly to 12V.  Hopefully that means the battery is now good.

Part of me wonders though, could my wiring be to blame.  Perhaps the right side is not charging like the left side and caused battery C to fail.
