Battery Switch
The battery switch is located in a panel in the port
rear of the cockpit. The switch is an OFF/1/2/1 &
2 (both batteries) battery selector switch identi-
ed by a red knob.
12 volt power can be supplied by either battery
1 or battery 2 separately or by both batteries si-
multaneously. The selector switch also directs the
charging current when the engine is operating.
For example: When the switch is set to battery
1, the engine and 12 volt system will be supplied
power by battery 1. Battery 2 will be isolated
and in reserve. Battery 1 will be charged by the
alternator. When the selector switch is on battery
2, the engine and 12 volt system will be supplied
power by battery 2. Battery 1 will be isolated
and in reserve. Battery 2 will then be charged by
the alternator.
When the selector switch is set to 1 & 2 (both
batteries) the batteries are connected in parallel
so the engine and 12 volt system will be sup-
plied power by both batteries. Both batteries will
be charged by the alternator. The 1 & 2 position
should only be used when starting the engine, as
this requires extra electrical power, or when both
batteries are low and need charging. Otherwise, it
is recommended that the selector switch be set to
battery 1 or battery 2 when the engine is operat-
ing. While in port, trolling, or at anchor, the battery
selector switch should be set to either battery 1 or
the battery 2. This will keep one battery in reserve
for starting the engine. The battery switch should
be turned to the OFF position when leaving the
boat unattended.
