Translation of the original instructions
SULFATED OR DAMAGED BATTERIES
The NEOSTART does not detect sulfated or damaged batteries.
• The battery is badly damaged when in charge, the anmeter pin goes up quicky to very high intensities. The battery is
permanently damaged.
• In the event of a sulfated battery : set the device to «BOOST» for the Neostart 420 and 620 or «BOOST 2» for
the Neostart 320 ad regularly check that the amperemeter indicates a charging current. As soon as the charging
current rises, set a charge that matches the battery capacity. If there are no improvement after 5 hours, the battery is
permanently damaged.
Warning - This must be done with the battery disconnected from the vehicle !
TROUBLESHOOTING
Symptoms
Causes
Remedies
The machine's anmeter does not
fluctuate .
Power supply problem.
Check your mains power supply.
Check that the device is on charge mode.
Clamps in short circuit or polarity
reversal.
Check that the fuses have not melted and that the
circuit breaker is not tripped
The battery that you are trying to
charge is faulty.
Check the terminals' voltage with a voltmeter. If this
voltage jumps instantaneously to 2.5V per element,
the battery may be sulfated or damaged.
Voltage error (12 -24V)
Chck that the switch is on the right setting (12 or
24V)
Following intensive use, your device
has entered thermal protection mode.
Wait 1/4h so the device can cool down.
The charger is properly connected
but it does not charge the battery
Blown fuse
Replace the fuse by a new one.
Bad clamp connections.
Clean the terminals and the clamps. Check the state
of the cables and clamps.
Wrong charge settings
Check that the selected voltage matches the battery
voltage.
Following intensive use, your device
has entered thermal protection mode.
Wait 1/4h so the device can cool down.
The anmeter's pin goes above the
maximum marking while the
device is set to minimum intensity.
The battery is deeply discharged.
Keep charging using the minimum setting .
Voltage error (12 -24V)
Chck that the switch is on the right setting (12 or
24V)
Your battery has elements in short
circuit.
Damaged battery Replace the battery.
The fuse blows every time it is
replaced
Polarity reversal
Connect the + clamp to the battery's (+) and the +
clamp to the battery's (-).
Wrong charge settings
Check that the selected voltage matches the battery
voltage.
Current overconsumption on the
battery
Do not draw any of the battery's current during the
charge
The machine is charging a 12V battery
in 24V mode
Set the switch to 12V.
The fuse trips.
Starts are attempted while the device is
in charge mode.
Make sure to set the switch to « start » to prevent
damage to the machine. Reset the circuit breaker.

mode
Set the switch to 12V.
After charging for a whole day,
the end of charge indicator does
not switch on.
The battery is damaged
Change the battery.
The machine is charging a 24V battery
in 12V mode
Set the switch to 24V.
