Solutions:
• Ensure that the battery terminals are properly connected on both the controller and battery side
• Measure the battery voltage – it should be no lower than 22V DC for the D10/D10 Turbo when placed under load.
Underload testing:
- Disconnect the charger from the battery
- Remove the DC motor leads from the DC controller
- - Apply the DC motor leads directly to the battery, while measuring the battery voltage
- It should not be less than 22V DC under load
• Check for corrosive build-up around the battery terminals. If there is corrosion, replace both the battery and terminals
• Replace the battery
• Ensure that the ‘Mains Present’ icon is solid
• Measure the charger’s output voltage. It should be about 27V for the D10/D10 Turbo
• Replace faulty controller
