M-1008 k/30 army truck questions...

[Longhorn Man]

or would it be a k/3500... not sure when they changed the names... either way...
I'm sure we have a resident expert on them, or some guys who remember working on them in there army days... they were all but gonee by the time I got to wrench on gov stuff.
A guy at work was asking me since his sone just bought one, was asking about the daul electrical system. I was going off limited knowledge, but I told him that most of the truck is 12 volt. The starter, the injector pump, glow plug controller and radio hook ups were all 24 volt, as was the jump start plug in the grill.
Was this pretty acurate, or do i need to call him and tell him otherwise?
