What to do if GYS TCB 120 is properly connected but not charging?
- MMr. Jason HolmesAug 11, 2025
If your GYS Battery Charger is connected correctly but isn't charging, there might be several reasons. First, the fuse may be blown and needs replacement. Second, the clamp connections could be bad, so clean the terminals and clamps, and check the condition of the cables. Third, the charge settings might be incorrect; ensure the selected voltage matches the battery voltage. Finally, after intensive use, the device may have entered thermal protection mode; allow it to cool down for about 15 minutes.
