Generator starts and runs but does not transfer power to the house

Safety first: De-energize both utility and generator sources. Lock out and tag out breakers. Confirm with a meter that the ATS is not energized.

• Listen for operation: During a test (with proper safety), the ATS should make a distinct clunk when transferring. No sound suggests a control or coil issue.
• Inspect control fuses: Open the ATS and check low-voltage control fuses. Replace any blown fuses with identical ratings after investigating for shorts.
• Check control wiring: Verify that the Honda generator controller's transfer command wires are correctly connected to the ATS terminals and are not loose or broken.
• Manual transfer test: If the ATS design allows, manually operate the mechanism to ensure it moves freely. Binding or seized parts indicate the need for mechanical repair or replacement.
• Professional service: Because incorrect ATS work can backfeed utility lines, have a licensed electrician or Honda technician repair persistent transfer issues.
