to jump-start the engine of the
motorcycle.
A short-circuit can res-
ult if the crocodile clips
of the jump leads are accident-
ally brought into contact with the
motorcycle.
Use only jump leads fitted with
fully insulated crocodile clips at
both ends.
Jump-starting with a donor-
battery voltage higher than
12 V can damage the vehicle
electronics.
Make sure that the battery of the
donor vehicle has a voltage rating
of 12 V.
Remove the centre trim panel
( 110).
When jump-starting the engine,
do not disconnect the battery
from the on-board electrical
system.
Begin by connecting one end
of the red jump lead to the
positive terminal of the dis-
charged battery and the other
end to the positive terminal of
the donor battery (positive on
this vehicle: position 2).
Then connect one end of the
black jump lead to the negat-
ive terminal of the donor bat-
tery and the other end to the
negative terminal of the dis-
charged battery (negative on
this vehicle: position 1).
The spring-strut screw can
be used as an alternative to
the battery's negative terminal.
Run the engine of the donor
vehicle during jump-starting.
Start the engine of the vehicle
with the discharged battery
in the usual way; if the en-
gine does not start, wait a few
minutes before repeating the
attempt in order to protect the
starter motor and the donor
battery.
Allow both engines to idle for a
few minutes before disconnect-
ing the jump leads.
Disconnect the jump lead from
the negative terminals first,
then disconnect the second
lead from the positive termin-
als.
Do not use proprietary
start-assist sprays or oth-
er products to start the engine.
