This happened to me as well. There is a breaker in the battery compartment that looks like a switch. If it is thrown, you will get the low voltage message. It does not look like any breaker that I have seen before, so I did not know what or where to look. I happened to find a tech on the phone that helped me find it for my MH. I was stuck with the MH leveler down with one of the MH's wheels off the ground. I hope you find it and reset it by moving the arm on the breaker back down to position.
