To fix the self-leveling issue on a Skyjack SJ61T, follow these steps:

1. Check Wire #08 – Inspect for loose or broken connections between the platform terminal block and platform level switch S19. Test continuity and replace if defective.

2. Inspect Platform Level Switch S19 – Check continuity through the switch while activating the level-up function between wires #08 and #41. If no continuity is found, replace the switch.

3. Check Wire #41 – Inspect for loose or broken connections between platform level switch S19 and the platform terminal block. Test continuity and replace if defective.

4. Examine Diode D41 – Located in the platform terminal block, check if the diode is open. If defective, replace it.

These troubleshooting steps should resolve the self-leveling issue.
