- I parked the truck. It ran superfine.
- I come back a few minutes later, it would not start... Nothing. Nada. Zip...
- I had no lights too. I figured it was the battery, so I replaced it. Nothing.
- I take booster cables and jump the starter (positive on starter - negative on frame).
It starts!
er... I may have answered my question writting this: a short on the positive cable? (The battery is NOT clamped down in its box, it kinda moves around, I'm ashamed to say...).
I'll replace that cable in the morning but could there be anything else?
