If it is like the Carefree, there are two terminals near the motor (depending on model you may have to take off the cover) that you can jump directly from any 12v source (like your car battery if the TT battery is dead). Our trailer even has about an 8' length of wire with gator clips provided. If the motor turns the wrong way, reverse the leads. Never had to do it, but I know how if needed.
