Leisure battery
Your vehicle is equipped with a rechargeable leisure
battery that is located in a dedicated battery
compartment within your vehicle. Locations of
leisure batteries vary from model to model, so please
familiarise yourself with your battery location before
using your vehicle for the first time.
The battery is charged via the on-board charging unit
when the vehicle is plugged into a mains supply, or
via the vehicle alternator whilst your vehicle is being
driven. If you vehicle is fitted with a solar panel, this
will allow the battery to be charged when light levels
permit.
CONNECTING AND
DISCONNECTING THE
LEISURE BATTERY
Please ensure that all cigarettes are
extinguished before working in the auxiliary
battery compartment. Switch o all appliances
and lamps before disconnecting the battery.
• Release the securing bolts or straps from
the leisure battery.
• Carefully remove the battery from the
battery compartment, taking care to
support its weight.
• Release the battery terminals using a
suitable zed spanner.
To refit the battery, simply reverse the above
procedure.
Please ensure the battery is located safely and
securely before driving your motorhome. Any
replacement auxiliary battery should be of the
same type and specification originally fitted by
the manufacturer.

Generators
If a generator is fitted, the vehicle must be regularly serviced to achieve the optimum performance. Engine speed
is used to govern the output and frequency of the unit in KW and Hz, and if this is allowed to vary beyond a safe
level, permanent damage could be caused to certain pieces of electronic equipment, such as 12v chargers.
Replacement fuses
When replacing a fuse, please ensure it is the same rated current as the original one fitted to the unit.
