No power from battery to trailer

[clockmanjim]

Getting ready for the first outing of the year and I ran into a snag? I'm not getting any power from the battery to the interior. I've got a 2015 Roo 21DK. I've gone through the battery disconnect ordeal and the only thing I cam come up with his a reset switch under the frame. Lead comes from the battery and goes through this little switch, it has a very small button, that when pushed is suppose to reset the power. I feel pretty confident this is what the problem is, but curious if anyone else has run into this. Here are pictures of the culprit.
Thanks for any help,
Jim

If you have a voltmeter is there power on both sides on the breaker?
Red to one side of breaker, ground to battery ground. Then red to other side of breaker and black to battery ground.

Thanks, I'lll check that out. Is that what that is, a breaker?

Yes, it is a circuit breaker.

Had the same thing on mine the first time out, had to replace the 40 amp fuse that is along the driver's side of the frame, between the battery and the cabin. It may have been a 30 and I put a 40 in it.

If you check it like imusa said in his post and find you need a new resettable breaker they are available at any auto parts store.
List: Circuit Breaker | O'Reilly Auto Parts
check the fuse in the green holder also.

I did check the fuse and it appeared to be okay. I guess changing it wouldn't hurt.
Thanks,

Thanks,because the reset switch won't work, I'll probably replace it Thanks for the tip about O'Reilly's

Please consider using a multimeter to see if you have 12v on both sides of fuses or circuit breakers . when you find a side without 12v, you found the problem. Otherwise you're just guessing

The item in your picture is called a resettable circuit breaker. With the quality of Chinese's parts, .... I would keep spares around. I've replaced some of mine with a waterproof fuse. CBs, fuses should not "blow" as routine. If one went, you had a problem: find the problem and repair or remove it.

X2. My 2012 doesn't have any resettable fuses, and I've never had any problems. I have helped several friends with newer rigs replace their resettable fuses with either quality ones or real fuses. In every case the OEM resettable fuse was junk and popped off continually. After replacing, there have been zero problems.

Had same problem. The ground wire that is attached to frame by the wires you see; remove it, clean everything (shinny) and re attavh.

That happen to us years ago when we had a TT,,, had to go to RV shop on our way North,,, teck replaced it for us,,, I bought a extra to carry with us,,, had it about 8 years and never needed it !!! still have it somewhere ???

I was under mine this wknd and noted both nuts were loose that secure the wires to the breaker. FR never included any method to retain the nuts. So I added star washers.....should add some loctite too.

Ok, I have a multimeter. I have never used one before but I'm assuming I put it on the D.C. Setting. If I understand correctly. I put the red probe on the lead coming into the breaker, the black probe goes where? If I have powe there, then I would put the red probe on the green wire and go through the same process. Is that correct?

Black on ground, the white wire with the yellow crimp connector held down by the corroded screw. Red to each side of the breaker one at a time, if the breaker is working, both sides will show 12vdc.

Anyone that owns an RV must have a Multimeter and learn how to use it !!!

[jehrbear]

Set the Multimeter to 20 volts DC,
starting at the battery, check your voltage, should be 13 ish volts plus or minus.
Test using the multimeter leads, and touch the red one to your connector, one to a ground, before and after each section. You should get a reading each time. If not that's where your power stops. Could be a resetable fuse, key disconnect, or a bad wire.

I had a similar event last year, my case was the key disconnect switch dealio had failed...$5 part online, but my dealer fixed me up quick as it was still under warranty.

Free-with-coupon ($3 without) multimeter, or 12v test light from Harbor Freight is more than good enough, leave it in the camper.

I want to thank everyone for their tips & info. I replaced the breaker ( which I'm told is now automatically resetable) and I'm happy to report that I now have power through the battery.
Thanks again to all
Jim

Here's a 40 amp unit hidden away from dirt and dust...
and got rid of the one under the trailer...
consider this next time it goes bad.
