Electrical Help Needed

[grntgil1]

I hooked up to go dump before the freeze. Everything was working well. I get back to park it, and I have no power to anything. Battery is full, per my charger, and it was hooked up to my running truck. No jack power, no slides, no lights, and no power to the inside panel that tells me tank levels and battery power. I changed the inline fuse to the jack and still nothing. The exterior lights and blinkers worked fine. The fuse looked to be good though. any ideas where I can start this trouble shooting? Oh, it's a 2019 Cherokee 264dbh travel trailer

TIA

Did you check the voltage of the battery with a multimeter?
How long had your R/V sat without using it before you "hooked up to go dump"?

You've got to start with the basics and that is voltage at the battery.
If that is good we can move on to things like, do you have a battery disconnect switch? and is there a 12v circuit breaker near the battery that needs reset?
Are the battery connections clean and tight?

Is there a tripped 12 volt circuit breaker under the tongue of the trailer?

[grntgil1]

it has only say about a week since we last had it out. i need to go buy a multimeter. my battery charger seems to think it's full. i hooked it up and it pegged out at 100. connections are clean and tight. i need to go back and dig around under to find the breaker. I called a funtown RV help line and the guy assures me that's what it is. I don't have a battery disconnect switch that I'm aware of. Again, it all worked and after dumping nothing worked. I just wish they made these switches and breakers easier to locate.

What battery "charger" is showing 100%? If it is the built in converter it will always show 100% if plugged in. What doe it say unplugged? What is the voltage at the battery?

The resettable breaker should be under the frame near the hitch it looks like the photo below. Press the small button on one end. Note color of cover if used may be different.

Thanks guys. I’ve gotta go dig around under the camper after my meetings. I hope you’re right about the breaker.

If it sat for a week, the parasitic drains could have the battery dead.

Most stand alone battery chargers I've seen and own, when the meter pegs to 100% that means the charger is charging at 100%, not battery condition.
Dead battery!

Haven't owned one in awhile, but yeah, that's how I recall the meter working also. 100% was a pretty low or dead battery.

All digital chargers I have ever owned show the percentage of charge in the battery. When the charger showed 100% the battery was fully charged. I have never seen one that is telling you the amount of charge going into the battery.

You could be right.
Maybe I confused it with the "Full Charge 100%" LED indicator light.

[dbledan]

If the TV was hooked up when you checked it could be because the TV alternator was trying to charge the battery when you checked it. That would show voltage enough to indicate a full battery same as the converter would.

Disconnect everything (shore power, Tow Vehicle) and check again or just disconnect the battery and check it directly to know if the battery is dead. Anything else may be giving a reading from something else.

Hoping for a breaker or fuse. Even a dead battery just means it needs a charge and a shorter life.

FIXED!!! I learned so much in this process. Thank you everyone. I learned that I have auto resetting DC breakers, where the water line low points are, how to empty the hot water heater, the reason we've not got hot water in the past 3 months is because there is an on/off switch by the hot water heater that we've never touched, what an anode rod is, how to remove it, how much it sucks trying to put it back in, where the battery charger fuse is on my new f250, all the fuses I need to carry with me that I didn't have, but do now, I don't need this $700 4 point Equalizer sway control on my F250, and that nothing will work if you have a bad battery with a bad cell. Main lesson learned, pull the battery and go directly to O'Reilly to have it tested.

Great! Glad you found it!

Now here's another thing you might want to consider in your learning process... buy a $5 battery hydrometer and check the cells in the battery yourself in less than 5 minutes.

I'm not saying O'Reilly would pull one over on you but at least you'd know for sure when you showed up and they see a customer 'thinking' they may have a bad battery.

[grntgil1]

just so happens I have amazon open right now and I'm buying it. thank you!!

I'm not seeing anything for $5, but I don't mind paying a little more. Is there one you suggest off Amazon, and how does it work?

This looks to be a popular choice. I think I get it. Just pop the caps open and suck up some water and get the reading??

Here's one on ebay for less and a Google search found lots for $5-10.
