One Pole Grounded Return System
This configuration implies that the battery negative is bonded to a ground potential,
typically at the engine negative terminal. This is done in order to polarize the DC elec-
trical system.
Note:
This arrangement is not suitable for steel and aluminium vessels as this might
cause electrolytic corrosion of the hull.
