Problem
The battery charger has switched itself
off.
Possible cause
The solar panel has an overvoltage.
The ambient temperature is too low.
The alternator is overloaded.
The starting battery and/or its connec-
tion cables are not clean.
The alternator is overloaded. A voltage
drop on the positive side (output cir-
cuit) has occurred.
The alternator is overloaded. A voltage
drop on the negative side (ground cir-
cuit) has occurred.
Suggested remedy
4. Gel batteries only: Ensure that
there is no odor coming from the
starting battery.
5. Ensure that the ambient tempera-
ture is not too high (see
data on page 25).
6. Ensure that the starting battery is
not swollen.
7. If necessary, replace the starting
battery.
Replace the solar panel.
This is a normal protective mechanism
when the charging curve for flooded
and lLiFePO4 batteries has been se-
lected.
1. Ensure that the starting battery
voltage is more than 13.3 V (11.4 V
for Euro 6 vehicles).
2. Ensure that the connection cables
and starting battery are clean.
1. Connect a multimeter to terminal
B+ of the alternator and the posi-
tive terminal of the starting battery.
2. Switch on the engine, radio,
lights, and ventilation of the vehi-
cle.
3. Ensure that the measured voltage
is less than 0.2 V.
4. If a voltage of more than 0.2 V is
displayed, contact an authorized
service agent.
5. Ensure that all cables, sockets, and
connections are intact, clean, and
corrosion-free.
6. Disconnect the multimeter.
7. Reconnect the starting battery.
1. Connect the negative connection
of a multimeter on the housing of
the alternator or on the ground ca-
ble.
2. Connect the positive terminal of
the multimeter to the negative ter-
minal of the starting battery.
3. Switch on the engine, radio,
lights, and ventilation of the vehi-
cle.
4. Ensure that the measured voltage
is less than 0.2 V.
