• Protections :
The GYSFLASH 4.12 has several features to protect it against short-circuits or polarity inversion. It has an anti-spark
feature which prevents sparks whilst connecting the device to the battery. This charger has double insulation and is
compatible with vehicle's onboard electronics.
The GYSFLASH 4.12 is fitted with an integrated temperature probe that ensures that the charging current is adapted to the
ambient temperature to prevent internal electronics' overheating.

• Make sure that there is no power consumption (normal
or abnormal) in the vehicle circuit.
• Check that the clamps are properly connected.
• After following these steps, if the indicator stays on, the
sulfated/damaged battery must be replaced.
• Check that the clamps are properly connected.
• 24V battery connected.
• Replace the battery.
Ambient temperature is too high, cool the room.
