Battery not charging, may need new converter what to look for?

Long story short, I've had my trailer for about 2 years and never had a problem till now. For some reason, my battery isn't charging when plugged into my outlets at the house. I'm a complete noob when it comes to electricity. When I plug in my trailer to an outlet at home, I get power, ie lights etc. work, but my battery isn't charging. This is the first time it's happened, as before our last trip in June, my battery charged just fine. I've checked the 40 amp fuses at my panel, and they both look ok, which leads me to believe I need a new converter. What do I need to look for when replacing it? Are they all pretty much the same? Size/dimension wise, do units all fit the same? Which amps should I get etc? We're leaving on a trip Friday, is this a relatively easy job? Thanks.

Not sure if this helps, but a buddy has a portable charger he hooked up to my battery and was able to charge it.

Check the resettable breaker on the tongue. ( see below). Pull the two 40A fuses and test them it can be hard to determine if they are good in while in the panel If you need to replace the converter most are the same footprint. I suggest Progressive as they do a better job.

Thanks! Bikendan informed me of this breaker on a different thread in the Roo section. I'll pick up a few 40 amps just in case and look at the converters if resetting the breaker doesn't do the trick!

Do you own a multi-meter and know how to use it?
Basic, simple tests will tell you what's going on before you spend a bunch of money throwing things at it.

Hi,

I had a brief encounter with this exact issue the other day. All 12 volt systems worked inside, but my monitoring equipment showed the battery wasn't charging.

Turns out I had inadvertently hit the battery cutoff switch. When I repositioned it, the converter immediately started charging the battery.

FWIW.

Thanks richp, but the cutoff switch is in the correct position to charge. Appreciate it though! @5picker I do own a multi-meter. My ability to use it is questionable though lol.

When all else fails before spending any money pull the battery and have it tested to see if it will take a charge. Most places that sell batteries will load test them for free.

X2... and notice "LOAD TEST" - not the same as checking voltage post to post.

My buddy charged it with his portable charger when I stored it at his house on Saturday. I assume it held a charge because I was able to operate my power jack. Come Sunday, no juice in the battery. Of course something always comes up before a trip right? lol

There is a converter "load test" to see if the converter is OK as well.
It may be putting out 13 plus volts "no load", then wimp out under load.

This procedure is for the 55amp converter.
