Generator attempts to start multiple times, then locks out with E13 on the display.

Safety first: Allow the starter to cool for several minutes between crank attempts to avoid overheating. Turn OFF the generator and disconnect the battery before inspecting the starter circuit.

• Check battery and cables: Verify battery voltage and cable tightness as described for E03. Low voltage can cause slow cranking and start failure.
• Listen to cranking: If the engine cranks slowly or clicks, suspect the starter motor or solenoid. If it cranks normally but does not fire, focus on fuel and ignition.
• Inspect starter solenoid: Locate the starter solenoid on or near the starter. Check for loose connections and burnt terminals. Use a multimeter to verify that the solenoid receives a start signal from the controller.
• Verify fuel and spark: Confirm that fuel is reaching the engine (see E04) and that spark is present (see E10). Correct any issues found.
• Clear lockout: Many controllers require a manual reset after a start failure lockout. Follow the DuroStar manual to clear E13, then attempt a start only after resolving underlying issues.
• If repeated failures occur: Continued cranking without diagnosis can damage the starter and battery. Have a technician perform a full start‑system evaluation.
