new battery - no internal power

[tigerbaywarrior]

So my first job was to replace the battery. Replaced with a good battery and covered back up.
The slide moves in and out but I have no internal power. I tried the GFI. None of the breakers are tripped.

Any ideas?

By internal power, do you mean at the outlets, or lights? Also, are you plugged in to shore power?

Not plugged into shore.

Nothing is on internally. No lights, no microwave, no power anywhere.

OK. You won't have any power to the receptacles / microwave / AC / etc. without being plugged in to shore power. The lights are going to be 12V (either supplied by the converter when connected to 110V, or by the battery). That your slide works doesn't surprise me. On most of the trailers I've seen, the slides / electric stabilizers / electric tongue jacks are wired direct with inline fuses or breakers. That it works tells me that your battery is good and you aren't getting any 12V past the converter. The first thing I would try is making sure the battery disconnect didn't get switched off (if you have one) and there isn't a blown inline fuse on the positive side coming from the battery. You could also try plugging in and seeing if the lights come on. If they do, the problem is between the battery and the fuse panel. If they don't, it may be a converter problem.

Ah...also, since you just replaced the battery, make sure you didn't accidentally leave a wire disconnected at the battery. Sometimes they have several.

There was only 2 wires - one for each terminal. I do know the lights worked when I purchased the trailer but it was hooked up to shore - sneaky dealer probably knew something was up.

I'll have to remove the fuse box and see if the wiring is good. The wires look pretty straight forward. Could the fuse box itself have any issue? I'm guessing if the fuses were bad, shore hook up wouldn't work.

if not plugged into shore power, microwave, a/c and outlets will NOT work.

putting in the battery, many newbies accidentally trip a resettable breaker that's located along the tongue, between the battery and the front of the trailer. should be a little black button on the side that resets it.
if the battery's charged, this will restore 12v things inside, like lights, radio, furnace.

Don't forget to look for a disconnect switch...probably looks like an old car headlight switch (push / pull). You may or may not have one, but your lights will run while plugged in if it's pulled. Your converter won't charge your battery while plugged in if it's pulled also. Just something to check on.

If there was something wrong with the converter, it probably wouldn't supply 12V to the lights while plugged in either. Easy enough to plug it back in and check to see if the lights work. Before you pull anything apart, trace the positive cable from the battery back. I agree with Dan, it's probably a fuse or resettable breaker that's inline between the battery and the converter.

I can't find anything outside between the battery and the fuse box. No converter externally. None of the inline fuses are blown. Maybe the large fuses?

[tigerbaywarrior]

Ahah! I found a tiny switch where the negative ids wired to the chassis. I mean tiny! Pressed it and I have 12v power.

Into the next challenge. Thanks for all the help!

Look for the main converter to battery fuse.

It looks like a small box with two terminals on it. (see photo)

On a travel trailer it is under the frame and on a 5th wheel it is located under the pin box (in mine) close to the battery. There is another located in before that, but because your slides work, that one is good.

Look for corrosion at the terminal or a popped reset button located on the side.

Yeah, I found it. I was looking for a button labeled "push me newbie". That little sucker it's small!

Thanks for posting the pictures.

Sorry I was late to the party. I need to add this post to the FAQ
