If a motor won't move:
- Verify power supply at the Node.
- Check fuses.
- Use a multimeter on the motor channel:
- Extend should show +12V DC.
- Retract should show -12V DC.
- If one direction fails, replace the node.
For overload faults (red wrench icon), check the motor amperage draw vs OEM specs.
For hydraulic slides, confirm the battery is fully charged and pump/solenoids are operational.
