B4000 4X4 battery charged, but nothing works

I checked the battery, and it's fully charged. Engine won't even click. There's no power in the cab at all. No lights at all. Even the door locks don't work.

I haven't tried to push start it yet, because it's parked with a building in front and on a slight incline to the rear. The 2 folks living in the house aren't enough to get it moving.

Ideas?

Thanks!

Have you checked all your connections. even those to your ground cables and your positive cable to the starter/junction box? also, have you checked fuses?

and are you sure your battery is putting out the proper voltage?

Thanks for the reply, DoctorCrobe.

All connections seem to be good. I haven't had a chance to check fuses, so maybe that will be my weekend project.

If I can't find a blown fuse, what next?
