If your unit shows no signs of life, try the following steps:
Test another power source
Plug NJORD© GO into a different 3-phase outlet.
Test with another vehicle
If possible, connect it to a different car to rule out communication or lock issues.
Check LED brightness in the app
Open the CTEK app and verify that the brightness setting isn’t set to 0, which would turn off all visible lights on the device.
If the unit is still unresponsive after these checks, the charger is likely faulty. Please contact your retailer to arrange a warranty claim or replacement.
