supplied with voltage even when the battery master switch is activated.
Vehicles with a battery at the rear are fitted with a jump socket that is live even
when the battery master switch is not activated.

activated in different ways. The battery master switch can be activated with the
battery master switch handle, an external switch or a switch in the instrument
