Fuse box under hood, passenger side, next to fire wall.

Take lid off and start pushing all the fuses and relays in to make sure they are seated fully.

Main battery might not be holding the charge. Connect the charger and see if the dome light works then. If so, that battery is probably stone dead.

Check the battery connections, especially the ground.

If the fusible link got popped, that would cause what you are seeing also. That said, I can't find any info on where it is located on the gladiator. It is generally somewhere on the firewall, all power routes to it before going to the fuse block.

And if things were apart to replace the aux battery, and the cable (ground or negative for the aux battery) wasn't disconnected from the main battery things could still be hot down there and perhaps a fuse or link blown.
The two are tied together at the main battery as I recall.

No dash lights, headlights or door open dome lights seems like there's no ground connection to the batteries. If you have a voltmeter, measure across the main battery terminals to verify voltage, then measure from the main battery positive to a good body ground.

Drop by autoparts store and get old fashioned test light. They put some load on the circuit. Clip one end to a good body ground and start probing. I assume it was working until batteries were replaced?

Any follow-up on this problem?
