Electric jack and stabilizers have no power

[Glenn Fontenot]

A few days ago I heard a click/tick noise near the batteries outside on the hitch about every eight seconds. I went inside and the lights in the RV would dim each time it clicked and the volt meter would drop a few volts. I had the heater pads on for the holding tanks and I though perhaps they were cutting on and off causing the situation. The temp was below freezing and it was too cold for me to stay out and check anything. Now, two days later, it has warmed up and I tuned off the tank heaters. There was no noise coming from around the batteries before I tuned off the heating pads and I'm not hearing anything at present. Now my electric jack and stabilizers won't work. Everything else in and around the RV that is battery operated is working. I was able to check a fuse near the battery and it is good. The light on the electric jack does not come on so I'm sure there is just no power going to the jack and stabilizers. Again, I'm not sure if the noise I heard and the lights dimming are associated with this new situation. It was so cold when I first heard the noise I didn't stay out there very long so I didn't even think of trying the jack or stabilizers. I don't know if they were not working then or not. Any suggestions as to what the problem could be?

Please add the year/make/model of your RV to questions like this, and describe the equipment involved as well. Nobody here knows what you have and can only guess. I gather it's a trailer, with an electric tongue jack and also electric stabilizers or maybe electric leveling jacks. Are the stabilizer jacks part of the same system as the tongue jack, or are they independent of each other? Brand names might be helpful too.

Typically powered jacks are directly wired to the batteries and have their own fuse(s). The only thing they typically have in common with your interior 12v systems would be the batteries themselves, so it's not surprising the rest of the 12v stuff works. I'd focus on finding how the tongue jack is wired to the batteries and expect to find a high amp fuse there, in the 20A-40A range. The electric stabilizer or leveling jacks likely share the same fuse & wiring.

Sorry I thought the post would include the make and model of my RV. I have a 2023 Flagstaff 25 FBLS TT.
In addition, I've decided to just manually lower and raise the jacks by the manual says to disconnect the power to the jacks first. I'm not sue how to do that but if they are not getting power anyway will it make any difference?

In addition, the jacks are Lippert PSX2. I don't see any fuses directly for them. the only fuse I see is one going to the jack and it is only a 15Amp. the fuse is good but I don't show any power going "to" that fuse either.

You have to add that info to a signature line in your profile. Once that is done, it is automatically added to every post you make.

The simplest explanation is the one Gary pointed to. It's likely the 20-40A fuse closest to the battery(s), if that's blown nothing else will get current. Loss of ground will do that too, so maybe check both.

Did you try them both electrically to see if the work?
