Controller displays E17 and logs during cranking phase

Safety first: Immediately stop the generator if the starter remains engaged. Disconnect battery negative to prevent further damage.

• Inspect starter solenoid: Check for signs of overheating or melting. Replace the solenoid if contacts are welded.
• Test starter relay: Locate the crank relay in the control panel. Verify that it de-energizes when the engine reaches running speed. Replace if it remains stuck closed.
• Check wiring: Inspect the wire from the relay to the starter solenoid for shorts to positive. Repair any damaged insulation.
• Controller settings: Confirm that crank disconnect parameters (speed or voltage threshold) are correctly set in the Wacker Neuson controller.
• Reset E17: After repairs, reconnect the battery and test start while listening for proper starter disengagement.
