Controls and Indicators
Battery Selector Switch
The battery selector switch allows you to isolate the boat from the
batteries, and switch from one battery to the other, or even operate
on both batteries. The identification of each battery as well as the
position allowing both to be used may differ depending on the
switch manufacturer, however, with any switch it should be easy to
determine how to select the desired configuration.
Under normal conditions, the switch should be set to one battery
or the other and almost never to the position for both batteries.
This will keep one battery in reserve should the other fail. Battery
selection should be done when the engine is off. Alternate batteries
daily. The switch can also be set to a position that turns off both
batteries isolating the boat from the batteries.
Avoid the possibility of personal injury or
death from an explosion and/or fire. Never operate the
boat with only one battery installed and the Battery
Selector Switch set to the position for both batteries.
The positive battery cable end of the missing battery will
be at full battery voltage and could short out against
metal components possibly causing an explosion
