Controller displays ESTOP or EMERGENCY STOP and generator will not crank.

Safety first: Ensure the area is safe before resetting any emergency stop device.

• Reset E-stop: Locate the red emergency stop button on or near the generator enclosure. Twist or pull to reset, depending on design.
• Inspect wiring: Follow the E-stop wiring harness from the button to the controller. Look for damaged insulation, loose connectors, or moisture intrusion.
• Test switch: With power off, use a continuity meter to verify the E-stop switch opens and closes correctly. Replace if it does not operate reliably.
• Controller input: If the E-stop circuit tests good but ESTOP remains, the controller input may be faulty and the controller may need replacement.
• Clear the code: After resetting and repairs, cycle the controller to OFF then AUTO and attempt a start.
