Motor Park Test
- Stop output arm about 90° past park position for this test. Make electrical connections as shown. Motor output arm should: Rotate in normal direction, reverse rotation for 10-15°, stop rotating while crank pin moves outward, then stop in park position while current draw drops to zero.
- If motor reverses more than 15° or if motor stalls or jams while rotating in the opposite direction, replace arm and gear assembly. If motor does not run or park, check wiring before replacing motor. For any other problem, check gear cover and switch assembly.
- To test motor switch, first check for good ground at motor. Check park switch cover screws and ground strap for tight connection. Remove 3-wire connector at top of motor and connect a ground jumper to green wire terminal. Test the other two wires for continuity. If not present, replace or repair park switch.
