Batteries

[twotravelers]

We have a 2015 Mobile Suites with hydraulic auto-leveling. Inside the control box for the leveling, there is a button to pull out labeled "Battery Disconnect. In for storage. Out for use only." We thought that only applied to using the hydraulic leveling. Two months ago, when we were ready to hitch up and travel after having the MS plugged in for five months, the batteries were dead and we couldn't raise the RV.
CoachNet led us through some diagnostics and said the batteries weren't being charged when the trailer was plugged in to shore power! We pulled out the switch to the "in use" position, let the batteries charge for 30 minutes and we were ready to go. OK, we can work around that.
Yesterday, here in Gallup, NM, the power in our park went out. Then we discovered we had no 12-volt power to operate the propane refrigerator or hot water heater or lights. That seems to mean we have to unlock and open the door to the hydraulic leving system to use 12-volt power. This doesn't make sense. Any advice? Similar experiences?

That switch isolates the battery. If not on, there will be no 12 volt power. Unless I am pulling out the battery, I leave the switch on. I have also had the same experience with no power and realized I had turned the switch off.

I leave mine on all the time also. I had a scare not long ago when I went to bring in my slides and they would not move. My battery disconnect is located in the side compartment where my landing gear switch is and must of been pushed in - easy fix once I found it.

We'll try it

We thought that closing and locking the door on the controls for the leveling system pushed the switch in. We'll have to see if it will stay on with the compartment closed. Thanks.

Closing the door does not push the switch in. The only time you want to push it in is if you are leaving it sit in storage without power pluged in. If you do not push it in then, the co2 detector and other parasitic draws will run the batteries down. By the way, at least on my unit, the landing gear will still work with the switch pushed in.

Leave the switch on all the time--way less hassles that way. And, yes, the hydraulics should still work with the switch off if the batteries are good.
By now, you may have hurt the batteries by draining them completely. I would check them for charge level and also load capacity.

Battery disconnect switch

Thanks for the replies. However, when we close the compartment door on our rig, the battery button is pushed in. Here are pictures of it in and out. We tried twice to close the door with the button out and each time when we opened it again, it was pushed in--off.

Any other suggestions?

Problem Solved

Today, my husband removed the front panel of the hydraulic controls, then loosened the two rings that hold the battery connect switch. By adjusting the position of that switch, we can now leave the batteries on with the compartment door closed and locked. Obviously, our switch was not installed quite right.
Thanks for all your comments.

Interesting--only time I have heard of this problem. Great that you found an easy solution.
