    OK, so it happened last night and I haven't even cracked the manual yet.
    Just figured I'd jump on here because I'll be thinking about it all day at work until I can get home and look into it.

    Truck was parked and I was using the spot lights on back of cab to illuminate the area that I was working.
    After about 30 seconds the alarm for leaving the headlights on started chirping. No biggie, I knew what it was from past experience.

    Fast forward 5 minutes and the spot lights went out.
    Cab lights won't work.
    Headlights won't work.

    This makes me think they are all on the same fuse, and I burned it out.
    Does this make sense?

    I was plugged into shore power at the time, so amperage shouldn't have been an issue.

    I think the only other times I used the back lights I had the engine running.
