Once you get the fuse/dummy fuse/no fuse issue worked out, you need to know that you are likely just barely getting 12V on the "aux" pin. Not enough to properly recharge a battery in a trailer.
He will need a meter (not just a test light) to determine that. Check voltage at battery with the engine running and compare to the 7 pin at the bumper.
