Rookie mistakes?

There is a fuse directly off of the battery on the positive cable. These are prone to blow if battery is connected wrong....even for a split second. Follow the positive cable from the battery and you should locate the in-line fuse prior to the cable disappearing into the TT.

Good luck

it would help some if you posted year, make and model of TT.

I picked up my new TT about a month ago and brought it home and parked it. I went out yesterday and plugged into 110 power and hooked up the battery. For some reason though I can not get the lights, radio and power awning to work. The microwave, TV and slide all work but nothing else.
I just thought I'd try this first before calling the manufacturer. We live miles from the nearest RV dealer.
Sorry if I listed this in the wrong place but there are so many choices.
Anybody have a clue to what I'm doing wrong?

OK, the "lights, radio and power awning" all run off the house battery.

The "microwave, TV" run off 110v, not battery.

The slide works off the battery, but is direct wired to the battery. It does not go through the 12v distribution system.

Note that all the stuff you say doesn't work is from the house battery.

I would be looking at the house battery connection. Taking the battery out you may have blown a fuse. Or, you have have hooked it up backward putting it back in, again blowing a fuse (hopefully).

ON EDIT:

I missed that this was a TT, so no chassis battery. That definitely points to a problem between the battery and the 12v distribution system. The slide is wired directly to the battery, and works, but the stuff that goes through the power distribution system does not work. That focuses your search.

Did you check all of your fuses?

Verify battery polarity by tracing the ground wire back to the frame.
If you hooked it up backwards then you blew the reverse polarity fuses on the converter.

Good luck,

Check all the circuit breakers and fuses. Turn breakers all the way off and then back on. Some converters (the thingy that supplies 12 vdc to trailer) have fuses in the output to the battery.

Everything worked when I picked it up. I unhooked battery and placed on charger. I hooked battery up again and it does open/close the slide w/o the 110 being plugged in so dead battery I think can be ruled out and I don't know about any disconnect/connect switches.
I guess I'll call the manufacturer when I have time to be on hold.
Thanks for the help though as I am lost.

Does it have a battery disconnect switch? If so, make sure the switch is in the correct position.

Check for battery disconnect.

Are you sure battery is not hooked up backwards? Battery disconnect switch off? Bad battery?
