ELECTRICAL SERVICES
11 TOGETHER WE’RE GOING PLACES
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 vary 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 by either 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.
Connecting the mains supply also activates the 230v
socket and various mains appliances.
All Auto-Trail vehicles utilise a combined power supply
unit (PSU) which contains the battery charger, 12v
fuses, mains residual circuit breaker and miniature
circuit breakers. Please familiarise yourself with the
location of the PSU unit prior to using the vehicle for
the first time.
CONNECTING VEHICLE TO 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, via the mains hook-up point on the vehicle.
• Locate the charger power switch on the power supply unit (PSU) and switch to 'OFF' before
connecting the mains supply.
• Connect the hook-up cable (orange with blue connectors) to the motorhome, and then to the
mains supply.
• Check the residual circuit breaker (RCD) operation: switch it to 'ON' (lever in up position), press
'TEST' button, RCD should now be 'OFF' (lever in down position). If button fails to operate, please
seek advice from an electrician.
• Switch the RCD back to the 'ON' position.
• Check the polarity of the mains supply by locating the reverse polarity indicator and ensure that it
is not illuminated. If illuminated, please seek advice from an electrician.
• Locate the miniature circuit breakers (MCB) within the PSU (adjacent to the RCD) and ensure
they are all in the 'ON' position. If any MCBs cannot be reset, this could indicate a fault or an
overloaded circuit.
• Locate the power switch on the PSU and turn to the 'ON' position. The switch will illuminate when
turned on. It is now safe to check the 12v and 230v equipment.
Please note: your motorhome should only be connected to a supply that meets that requirements of
BS7671 (ask site warden for more info).
