3.4. Voltage detection system
Your Booster is equipped with a voltage detection system. After the connection of the
clamps on the battery terminals of the broken down vehicle, a coloured led will indicate its
voltage, as follows:
n
the green LED next to the 12V connector lights up when the voltage detected by the
Booster is between 3V and 14,4V.
n
the orange LED next to the 24V connector lights up when the voltage detected by the
Booster is over 14,4V.
NB: if your vehicle does not start when the Booster is connected in 12V, it may be that your
vehicle starts in 24V:
n
and that its voltage is under 14,5V
n
or that you connected the Booster on the wrong vehicle’s battery (see point 3.2.).
In both cases, please read the instruction manual of the vehicle manufacturer to be sure of
the voltage of the vehicle at start.
If it is a 24V vehicle, resume the jump start considering the point 3.2.
3.5. Starting attempt
When using the Booster to start an engine, do not crank for more than
8-10
seconds
, and wait for a further
3 minutes
before a second attempt.
If after the 3rd attempt the engine does not start, it may be necessary to identify a further
cause for the breakdown.
NOTE: if your Booster is fully charged but the starter turns slowly, the vehicle’s or Booster’s
battery may need checking for short circuit.
