The original, electrical system of the motorhome can be represented in a basic manner by a
relay that connects the engine battery (and thus the alternator) to the service battery when
the vehicle has the engine switched on (i.e. the alternator is in operation and signal D+ is
active). Below is a representation:
The installation of the 3Lion + 3Link is very simple, just intercept in the original system
of the vehicle, the cable that goes from the service battery to the control unit or to the
battery combining relay which in the figure " Original system of the camper " is identified

it to pin 2 of the 3Link .
