What to do if the red “Input Voltage“ LED doesn't light up on my Rothenberger Battery Charger?

If the red “Input Voltage“ control LED on your Rothenberger Battery Charger doesn't light up, it could be due to several reasons. First, check the power supply to ensure it is providing voltage. If the power supply is working, inspect the mains cable for any damage and replace it if necessary. Another possibility is a defective red control LED, which would need replacement. Lastly, check the fuse in the main unit and replace it if it's defective.
