Locate the electrical control module (ECM) behind the right side panel–labeled "P/N 275-2050" on the housing. This unit regulates vertical movement and fault codes; trace the 16-pin connector to isolate power or signal disruptions. If the lift stalls mid-operation, check for corrosion on terminals 3 (12V input) and 7 (ground return). Clean with a 220-grit abrasive pad and apply dielectric grease to prevent future oxidation.
