PROTECTIONS
This device is protected against short-circuits and polarity inversions. It has an anti-spark feature which prevents sparks whilst
connecting the Gysflash to the battery. The Gysflash will not deliver current if there is no battery detected (no voltage in the clamps).
The charger is fitted with an internal 80A fuse (ref. 054653), to protect against misuse.

CAUSES
The polarity has been reversed on the clamps
Battery voltage too high
Battery short-circuited or damaged
Battery not connected or clamps in short-circuit
6V Battery connected
Consumption exceeds the output of the charger
Several consumers are active on the vehicle
Battery discharged

Connect the red clamp to the (+) and the black clamp to the (-) of the battery.
Charger not suitable (ex: 24V battery instead of 12V battery).
Change the battery.
Check clamps connection.
Charger not suitable.
Turn off electrical consumers to reduce power demand
GYSFLASH works to specification. Turn off consumers to check the battery is not
too discharged (see cause n°2).
Battery deeply discharged, the GYSFLASH delivers current to charge it. Wait
until the output current is below 10A to start the diagnostic.
