Controller displays 'Low Battery' or 'Battery Low'; generator may crank slowly or not at all.

Safety First: Turn the generator to OFF at the controller and open the DC fuse or disconnect the negative battery cable before servicing battery connections.

• 1. Inspect battery terminals: Remove the negative cable first, then the positive. Clean corrosion from posts and cable ends with a wire brush and a baking soda/water solution. Reinstall cables (positive first, then negative) and tighten firmly.
• 2. Test battery voltage: With a multimeter, measure DC voltage at the battery. A healthy fully charged 12 V battery should read about 12.6–12.8 V with the unit off. If below 12.0 V, charge the battery or replace it.
• 3. Check GE battery charger: With AC power present, measure voltage at the battery terminals. You should see about 13.2–13.6 V. If voltage does not rise above static battery voltage, the onboard GE battery charger module may have failed.
• 4. Inspect charger wiring and fuse: Verify the charger harness is firmly connected to the control board and battery. Check any in-line DC fuse between charger and battery and replace if blown.
• 5. Clear alarm and retest: After correcting the issue, set the controller to OFF then back to AUTO to clear the Low Battery alarm. Run a manual test to confirm normal cranking speed.
