Outside panel screen doesn’t work.

[Eliasfalcon154]

I have a Montana RV from 2013. I’m really new to this. I tried plugging into my car and put the wrong terminals in the wrong place when I connected it to the battery. I know I fried something there. Now the auto level doesn’t really work, I can’t see anything on the display, and it keeps giving me a BEEP sound every 20 seconds or so. I hope it’s just a fuse that went wrong. The inside of the RV has power, the AC, lights, microwave and fridge etc all turn on but I can’t use the slide function to open it. Any help?

In the corner above the hydraulic pump is a red inline 5a fuse.
It goes to the hydraulic controller, and tank heaters.

On my unit - when the batteries are low the Lippert level up panel will beep and show an error message (don’t recall the msg) - but it also says “press enter to acknowledge”. Press enter and the beep stops. That might solve one issue but it sounds like you may have other issues.

The beep may be from low battery. If you hooked the terminals up backwards, it could be that the reverse polarity fuses are blow in your fuse panel/breaker box and not allowing a charge to get to the battery.

If your sidles don't work you most likely have dead batteries. The beep is low battery. Test the batteries, Charge or replace them.
