Controller displays E16 and logs a fuel-related alarm; generator may shut down or refuse to start.

Safety first: Turn OFF the generator, disconnect the battery, and avoid open flames or sparks near the fuel tank.

• Verify actual fuel level: Use the mechanical gauge (if present) or visually inspect the tank to confirm fuel level. Do not rely solely on the electronic reading when E16 is active.
• Inspect sender wiring: Trace the wires from the fuel tank sender to the controller. Look for loose connectors, chafed insulation, or corrosion.
• Check sender mounting: Ensure the fuel level sender is securely mounted and not rotated or bent, which can cause the float to stick.
• Test sender (if equipped to do so): With the sender removed and using a multimeter, move the float through its range and verify resistance changes smoothly according to the A-iPower spec.
• If sender is faulty: Replace with an A-iPower-compatible fuel level sender of the correct resistance range.
