Battery Switches
Battery Parallel Switch
Your boat might be equipped with an emergency bat-
tery parallel switch located on the console. The switch
connects the engine starting battery in parallel with the
electronics battery if the engine will not start due to low
battery voltage. The switch controls a solenoid that
connects the engine starting battery with the electron-
ics battery. The switch is a three-position rocker
switch that is ON-OFF-ON. The center switch position
is OFF. Both the left and right switch positions are
momentarily ON when held down. When you release
the switch, it will return to the center OFF position.
If your engine will not start due to low battery voltage,
use the battery parallel switch to provide power from
the electronics battery. With the engine key switch in
the OFF position, push and hold the battery parallel
switch ON to either the left or right position. Note this
position. While holding the battery parallel switch ON,
try to start the engine.
If the engine does not start, turn both the engine key
switch and battery parallel switch OFF. Then move
the battery parallel switch to ON in the opposite direc-
tion. While holding the battery parallel switch ON, try
to start the engine.
The solenoid has two yellow fuse holders wired to the
battery switches. These fuse holders are located next
to the solenoid. The fuses protect the electrical wiring
between the solenoid and battery parallel switch.
Periodically check the condition of the two 10-amp
fuses located next to the parallel solenoid. A blown
fuse would not allow the battery parallel solenoid to
function in one position.
