Howdy! I recently purchased a December 78 and it has some interesting wiring (I know, I know, they all do). Currently I have the battery out while I am baselining the truck and when I put it back together I don't want to A. Fry the new stuff and B. I want to put it back together "correctly". I've attached some pictures. As you'll see the battery is a 24V and there is a shutoff switch which the PO said he installed because the battery slowly dies if it isn't started on the regular. My understanding is that these are 12 Volt trucks so I'm confused as to how the 24 Volt battery is working. HELP!
