Quasi-Update:
-My battery was giving me trouble for a while; I had to jump start if i wanted to drive it, and if I turned it off, I would have to jump it again. Swapped a different battery in, and now it'll start on its own. However, whenever I turn on anything in the truck (headlights, blinkers, fan) It really lugs the system, my clock becomes almost unreadable because it is so dim. And with everything there is a noticeable drop on the voltmeter. Is this a weak battery or alternator?
Sounds like bad wiring to me. Check your engine and chassis ground wires and your hot going into the fuse box.
