Battery not charging

[mets721]

I bought my 2014 Whitehawk 33bhbs two months ago. We are getting ready for our first trip and just found that the battery seems to have suddenly stopped charging. I moved the trailer and plugged it in on Tuesday. When I went to relocate it again today and unplugged it I noticed that none of the power jacks/stabilizers worked. I had to plug it in to get the equipment to work. Anybody know of any reasons why the batter wouldn't be charged after being plugged in for a week?

Check the 30A fuse at the battery and also the reverse polarity fuses on the converter.

Or tripped A/C breaker for the converter

Thanks guys. I pulled the 30amp battery fused today and it was blown. I never checked it earlier because I thought if that was blown, the trailer wouldn't have power while it was plugged in either. Guess I learned something new.

Keep posts clean. Had solar for couple years to be "green friendly" this year no good charge. Post with chalk on it. Cleaned now happy.

I was having a bit of trouble with batteries not charging. Poor connection at one battery. Just needed to clean and retighten.

Most often hooking up your battery wrong is the reason for blowing the in-line fuse close to the battery terminals. This also blows the two REVERSE POLARITY fuses mounted in the 12VDC distribution panel.

Just takes one quick spark haha...

having a multimeter around solves all of these problems. A fully charged battery will read 12.6VDC at the terminal and when you hookup to shore power this DC VOLTAGE should jump up to 13.6VDC. This tells you everything is connected and working between the on-board converter/charger and the batteries.

The inexpensive multimeter is available from WALMART and LOWES and any number of auto parts places for $7-$20. A must have item for all RV'ers.

I've already blown five battery fuses this season on my '14 White Hawk. Seems to sizzle every time the power jack hits full extention or full retraction. Back off the jack once you hear it getting close either way. And keep a pack of 30 amps close at hand!

I had a blown fuse when I picked it up from the dealer�� but...simple swap of the 30amp fuse did the trick.

Not sure if I'm in the right place, but we are having a problem with our Jayco 19H. I brought it home last week and plugged it in to the garbage to get the fridge cold. Everything worked fine… (I thought) We get to the camp ground and plug in to shore power around noon and by that evening all the lights were dim and an alarm sounded. The camper seemed to be running strictly off of battery not shore power. The owner of the camp ground did a quick fix and hooked up a battery charger then plugged that in to shore power and that got my through the next day. Any ideas on what this could be? I have read about the converter… Could this be it? If so, is that an expensive fix? Thanks for any and all info.

I think the converter is in the panel behind the fridge. Remove the harness on the 12vDC and ground, plug in the trailer, put a multimeter across the terminals and see if your producing DC current. I doubt the converter is too expensive but then again it is a trailer product.

A quick way to see if you battery is receiving 12-14VDC from the TT's battery charge controller is:
- Unplug TT from shore power
- Go to the main 30 amp fuse by the battery box.
- Pull the fuse
- Take a voltage meter like Roy posted
- You should read a voltage on the battery side of the fuse holder
- No voltage on the TT charge controller side
- Plug in to shore power
- Should have 12-13+ VDC on TT charge controller side and battery side
- If there is no voltage on the TT charge controller side
- Check the reverse polarity fuse and main 12VDC fuse in the controller

Not sure of your AC electrical skill level so I am not going to go into the AC portion of the controller.
