The CTEK MXS 3.6 is in standby mode with the yellow indicator light on because it is not detecting a proper connection to the battery. This may be due to one of the following reasons:
- The battery is not connected correctly. - The battery’s Under Voltage Protection (UVP) is activated. - The battery voltage is too low (less than 2V). - There is a poor connection or faulty accessory.
To resolve the issue and select a charging mode for trickle charging:
1. Check the clamps are properly connected to the correct battery terminals. 2. Inspect the quick connector and ensure good contact. 3. Press and hold the RESET button for 10 seconds to disable UVP. 4. Try the charger on another battery to verify function. 5. Once the charger detects the battery properly, select the appropriate mode for trickle charging (if available on the unit).
