4. There must be a main switch connected to the
starter battery positive (+) terminal. The main
switch should cut off power to all power consuming
equipment and should be switched off when the
boat is not in use.
5. If an auxiliary battery is in use, a main switch
should be connected between its + terminal and
the fuse block, and the (–) terminal and the termi-
nal block for the boat's electrical equipment. The
main switch for the auxiliary battery must cut off
all power consuming equipment connected to that
battery and be turned off when power is no longer
needed.
All equipment connected to the auxiliary battery
should have separate switches.
To simultaneously charge two independent battery
circuits, fit a Volvo Penta charge distributor (ac-
cessory) to the regular generator.
