Practical advice
Jump-starting where vehicle batteries are mounted side by side
Connect the negative cable to the (-
) terminal on the donor battery and
then the other end to an earthed
metal part that is bolted onto the bus
skeleton.
Note:
As far as possible from the discharged
battery.
Run the engine of the donor vehicle
at an elevated idling speed.
Start the engine of the bus to be
jump-started in the normal way and
let it run at idling speed.
Switch off the engine of the donor
vehicle.
Fully disconnect the earth connection
of the jump leads then disconnect
the positive cable.
Note:
To prevent voltage peaks, switch on the
more powerful consumers of the jump-
started bus, such as the lighting, heated
windows or ventilation, before you discon-
nect the jump leads.
