What to do if the indicator does not light up on my GYS ARTIC 4000 Battery Charger?

If the indicator on your GYS Battery Charger doesn't light up, it could be due to a short-circuit, open circuit, or polarity reversal. Ensure there is no power consumption in the vehicle circuit. Also, check that the clamps are properly connected. If the indicator still doesn't light up after these checks, the battery may be sulfated/damaged and needs replacement.
