Generator not charging battery

All of the sudden my generator isn't charging my battery. It is running the electrical outlets and such just not charging the battery. Every night I check the battery if I'm low run the generator for an hour or so and everything's fine. Went to do the same tonight and running the generator actually dropped the battery. I'm sitting here at 2am running the rv so I dont have to jump it in the morning. Any ideas? Yall have been great answering my stupid newly questions so far. It's a 2019 fr 3

Check the breaker in your panel for the converter. While the panel is powered, the breaker may be off. If that is not the case, check the converter itself and see if it is powered. If powered there should be 13.2 or more volts on the output, if that is not the case, turn it off and check the fuses (at least 2 depending on the converter model.)

If you have a 50amp service be sure and check for 2 breakers on the gen.

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant

As Cavie said check the breakers on the genny itself. It is possible one of the breakers could be tripped and you would still have AC power to some items on your unit. There are two AC busses (one buss by a genny breaker and the other buss fed by the other genny breaker) and one of them (the one that powers the converter) may be down. Just a thought. Of course, if both of your air conditioners run then there is no genny circuit breaker issue.

Ok guys please give me directions like a 5 year old. I checked breakers on generator. Both are ok. I have no idea where or what a converter is and how to check buses.

A converter takes in 120VAC and produces approximately 12VDC for the RV's use. Most converters are multi-stage which means that they measure the battery voltage and use that to determine what output voltage is best to bring the batteries up to full charge. Common voltages are 14.8 for bulk charging, 13.6-13.8 for absorbtion charging, and 13.2 for float charging. Do a web search on "flooded cell battery charging" to learn more about this.



If the converter is in float mode and you place a load on the battery, (ie furnace blower motor), the battery voltage will drop and the converter will switch modes which also provides power for the DC devices in the rig. Slides require a lot of power to run the motor and FR recommends that you always have the converter adding power to what's in the batteries when opening or closing the slides.

I know you think your explaining but I really dont understand. All appliances work with gen running but it is not charging the battery. I need to know why and a fix. Like I said simple. Like there is a switch here it should be on. Or if blankly blank is flashing do this.

This is relatively hard to diagnose from a distance. Not sure which FR-3 layout you have and Forest River seldom puts images of the "non-fancy" stuff on their site. However, if this is what your rear storage bay looks like, the converter is the metal box on the far right of this image, accessible from the basement door on the rear driver's side where your power cord is. The plug on the left of this image is where you plug in your power cord when using the generator.

The question is "is there AC power going to that metal box?" It should be a Progressive Dynamics unit. Hopefully it is not hard wired but plugged in...can't remember which it is on my 335, which has a very similar layout. If it is plugged in, unplug it and plug in something that uses ac power to see if the outlet has voltage. If it doesn't, go to the breaker panel (SB near the floor in the rear bedroom...press on the bottom of the large rectangular door and it will pop open) and check the breaker labelled "converter" and wiggle it. If it is loose, turn it off and then turn it on to see if that will reset the breaker. You can do this first if your want.

If there is power to the converter, there are two or three visible fuses (yellow 25 amp I believe) replace them if they are bad. If you can't check them...replace them anyway.

Now, if the breaker is popped or the fuses are bad, something else is wrong and since you have a new coach, take it to a dealer.
