One thing I did when mine did not seem to work was loosen the frame holding bolts from underneath, then try it again. Takes a ratchet and a socket set. A couple of turns on each bolt so the steps felt loose. If the steps work then, you have released the tension a bit and the steps are no longer tripping out on overload conditions. Why you have an overload becomes the issue. I ended up putting some shims under the bolts, then tightening it all up tight again and it kept on working. Low battery causes higher amps. Wear and tear causes round holes to become oblong. Use your jumpers to connect to a good battery and see if that helps.
