Help with Electrical

[jeepsailor]

Fellow RVers, Help, I went on at trip this last weekend and was dry camping and my battery died big time. I replaced it with a new group 27 100 amp hour battery and it died in the first night. But before it died we turned off everything, pulled all the fuses and shut off all the circuit breakers just in case. There was a draw of about equal to 2 sixty watt lights being on. (don't remember the amps) I am thinking short what about you? If I am right were do you think I should start? I have an 1809 Rockwood mini-lite tt.

I would say if possible pull out your power unit(where your 12v fuses are) then disconnect main feed to that to see if you get high draw still.

I guess it's process of elimation. You started off right with pulling all 12v fuses. The main 12v from battery to electric panel should be ran under camper, you should be able to crawl under there and visual check the cable. If you have further issues let us know.

Just so you know-- circuit breakers have nothing to do with your
battery. At least nothing to do with discharging.
There is a circuit breaker that powers the onboard charger.
Circuit breakers found in your power center are for the
120 volt AC side of things NOT the 12 volt DC stuff.

It's going to be a "treasure hunt" to find your problem.
In MY trailer I have 2 fuses that stand alone above or beside
the rest. These 2 fuses connect the onboard charger to the
battery to charge it. Did you pull them??? Was your battery
still being discharged with these 2 fuses out???

IF that's the case I agree with Jeepsailor. It's time to start
at the battery and work your way back.
Good luck!!

Check the Propane Leak Detector, it's not powered with the other 12 volt items.I believe it has an inline fuse holder. Is your CO detector 9v battery or hard wired to the 12 volt system, another possiblility?

There are few places that could draw that much current and not blow a fuse. Normal 12volt users are,
lights,
fridge control panel,
lp gas alarm,
vent fan(s),
slide motor(s),
Break-away brake power,
electric tongue jack,
and a few more I'm sure I missed.


There also should be a breaker under the front that could leak current.

As said earlier, just start unhooking one thing at a time till you find it. Don't forget to check the break-away switch. Those have been known to get wet and leak.

I want to thank everyone for there input it seems to have been the break away brakes again thanks to everyone.

Glad you found it and especially glad that you came back and let us know what it was.

Good call.
I completely forgot about the electric brakes
break away switch.

And thanks for telling us what you found!
I love a happy ending

Hope your brakes are still OK I have heard of them burning out from being left on - might want to check they are OK.

Me too. I've heard from folks who pulled the pin out
of the switch just to use the brakes for Parking!
Real bad idea.
OTOH I've heard from folks who pulled the pin either
on purpose or by accident and it didn't melt anything.
I hope jeepsailor's brakes are OK!!
