Generator controller displays E07 and engine will not crank

Safety first: Disable auto-start, turn OFF the generator, and disconnect the battery negative cable before inspecting the starter circuit.

• Check fuses and relays: Open the control panel and locate the starter fuse and starter relay (refer to wiring diagram). Replace any blown fuse with the same rating only after checking for shorted wiring. Swap the starter relay with a similar known-good relay if available.
• Inspect wiring: Follow the heavy cable from the battery to the starter solenoid on the Honda engine. Ensure all connections are tight and free of corrosion. Check the smaller control wire to the solenoid for damage or disconnection.
• Test starter solenoid: With the battery reconnected and using proper precautions, have an assistant attempt a start while you listen for a click at the solenoid. No click suggests a control issue or bad solenoid. A click with no crank suggests a failed starter motor or poor high-current connection.
• Bench test starter (advanced): If accessible, remove the starter motor and have it bench-tested at a service shop. Replace the starter motor assembly if it fails to spin strongly under test.
• If unsure: Because of the high current involved, if you are not comfortable testing starter circuits, contact a qualified technician.
