Electrical Services
All Auto-Trail vehicles have both a 12v and 230v
electrical system.
The 12v electrical system is supplied by a
rechargeable leisure battery that is located
in a dedicated battery compartment within
the vehicle (locations of leisure batteries
varies from model to model so please
familiarise yourself with your battery location
prior to using the vehicle for the first time).
The leisure battery is charged either by the
vehicle alternator when the engine is running,
or by the on board battery charger when the
vehicle is connected to a suitable mains supply
via the hook-up lead supplied with the vehicle.
Connection the mains supply also activates the
230v sockets and 230v lights (where fitted to
a vehicle), as well as various mains appliances.
All Auto-Trail vehicles utilise a combined
power supply unit (PSU) that contains the
battery charger, 12v fuses, mains RCD
(residual circuit breaker) and MCB’s
(miniature circuit breakers).
Please familiarise yourself with the location of
the PSU unit prior to using the vehicle for the
first time (individual specifications of PSU
units will be described in more detail later
in this section).
Connecting The Vehicle To A Mains
Supply
Your Auto-Trail vehicle is supplied with an
orange mains hook-up cable that will connect
your motorhome to a suitable power supply
on site via the mains hook-up point on
your motorhome.
