Safety first: Turn OFF the generator and disable auto-start. Disconnect the negative battery cable before working on the starter circuit.

Check battery condition: Even if voltage seems adequate, a weak battery may drop under load. Have the battery load-tested or temporarily connect a known-good battery of the correct rating.
Inspect cables: Follow the positive cable from the battery to the starter solenoid and starter motor. Tighten any loose terminals and clean corrosion.
Listen for solenoid click: During a start attempt (with safety precautions), listen for a distinct click from the starter solenoid. No click suggests a solenoid or control wiring issue.
Check starter fuse/relay: In the control panel, locate the starter relay and associated fuse. Replace blown fuses with the same rating and reseat the relay.
If E10 continues: The starter motor or solenoid may need replacement. Due to confined spaces and heavy cables, professional service is recommended.

Generator attempts to start but stops cranking and shows E10 on the display.
