Fuel · Alarm
The red over-crank icon means the engine did not start. Manual 100515 shuts the generator down so it does not damage the starter. In AUTO the printed cycle is 9 seconds crank, 10 seconds off, 5 cycles, then a 120 second lockout. Pressing OFF does not skip that lockout. You wait until the timer reaches zero before another start. The manual says to check that in-line fuel shutoff valves are open, and that a weak battery can keep the starter from reaching starting speed. A fuel-pressure (manometer) check is assigned to a dealer or installer.
Seen on: Champion home standby generators with the aXis controller covered by operator manual 100515. These are icon faults, not four-digit numeric codes.
Likely causes
- Fuel shutoff closed, or not enough fuel pressure.
- Battery too weak to crank fast enough. The manual points at the battery-charger 'no charge' icon.
Checks an owner can do
- Put in-line fuel valves in the ON/OPEN position.
- Check the battery-charger icon. If it shows no charge, test the battery the way the battery maker describes.
- Wait out the 120 second lockout even if you already pressed OFF.
When to call a pro
A manometer fuel-pressure test, and any over-crank that remains with the valves open and a good battery, goes to an authorized Champion dealer or installer.
