Probability is that you inadvertently swapped the wires when you were repairing the jacks/levelers. A DC motor doesn't care about the polarity, it will just change the direction the motor runs, electric windows, steps, electric awning motors and electric jacks all work on this basic principal. The control system on a unit that old is actually still pretty "dumb".
