Indmar Standard 360 Operator's Manual page 29

OFF position when an external battery charger is being used to
charge the battery(s) to avoid possible damage to the electronic
components on the engine or in the boat.
N OTE: Avoid turning the switch to any other position while the
engine is running. If the switch is turned to the OFF
position with the engine running, the alternator will be
permanently damaged and will not be covered by Indmar's
Limited Warranty.
1 Position is the main battery. Normally when the battery switch is
not OFF, it should be set on 1.
2 Position is the reserve or back-up battery and should only be
used if battery 1 has become depleted and the reserve battery is
needed to start the engine.
1 and 2 Position is available but not recommended, as power will
be drawn from both batteries and the alternator may not be able
to keep both batteries charged simultaneously. Position 1 and 2
would be used in an emergency situation where both batteries are
low and power is needed from both batteries to start the engine.
Once the engine has started, carefully select battery 1 or battery 2
to direct all of the charging current to one battery.
N OTE: Never use the charging systems' alternator to bring a dead
or undercharged battery to a fully charged condition. The
excessive current draw can overheat the alternator and
cause it to fail. If you have a dead battery, use an external
battery charger to bring the battery to a fully charged
condition.
Use caution when connecting the battery cables. Improperly
connecting the battery cables or using the wrong battery type can
damage electrical components. These damages are not covered
by your warranty.
When disconnecting or reconnecting battery cables, always
disconnect the negative (black or yellow) battery cable first. When
connecting battery cables, always connect the positive (red)
battery cable first.
Before disconnecting the battery, make sure the battery switch (if
equipped), ignition key and all accessories are in the OFF position.
