Generator will not start at all; no crank, no click from the starter.

Safety first: Ensure the generator is isolated from utility by opening the main AC breaker. Keep the controller in OFF while troubleshooting.

• Check battery voltage: Measure across the battery terminals. If below 12.0 V, charge or replace the battery.
• Inspect battery cables: Confirm both positive and negative cables are tight and free of corrosion at the battery and chassis ground point.
• Check control fuses: Locate the DC control fuses inside the control compartment. Replace any blown fuses with the correct rating and investigate the cause if they blow again.
• Test start relay: Have a helper command a start while you listen for a click from the start relay on the control board. No click may indicate a failed relay or controller output, requiring board or relay replacement.
