    I shut my truck off last night, ALL systems normal... Then, 20 minutes later, turned key to accessory position to roll up windows, and I have a complete electrical blackout. Not ONE single electrical system is energized. Batteries read 13.7. I've checked and replaced, just for kicks, the inline fuses in the battery compartment. I've physically removed, checked and reinstalled the grounding strap from battery to frame. All alternator connections are tight... any ideas?

    Pretty much turned out to be the issue... the lug for the main hot cable was severed at the nut.... crimped on a new one, rolling on... thanks, brother!
