Connecting jump leads:
• Connect each end of the RED lead to the
POSITIVE terminal (+) on each battery, and take
care not to short-circuit an end against the chassis.
• Connect one end of the BLACK lead to the
NEGATIVE terminal (-) on the battery that is fully
charged.
• Connect the other end of the BLACK lead to a
good CHASSIS EARTH, away from the fuel tank
and battery.
Remove the leads in reverse order:
• The BLACK cable is removed from the chassis
and then the fully charged battery.
• Finally the RED cable from both batteries.
