Typical battery functions

IMPORTANT:
Never connect an external battery
isolator to the stator of an Evinrude E-TEC.
Primary
•
Used as starting battery under normal operating
conditions.
•
Red (+) cable connected to battery selector
switch.
•
Primary battery is charged by connection to
main red (+) outboard battery cable.
Dual outboard installations can utilize the oppos-
ing outboard's primary battery as a secondary bat-
tery for emergency starting only.
Secondary
•
Used as back-up starting battery under abnor-
mal operating conditions.
•
Red (+) cable connected to battery selector
switch.
•
Secondary battery is charged independently
from primary battery.
Accessory
•
Not used as starting battery.
•
Isolated from outboard start function.
•
No red (+) cable connected to battery selector
switch.

Battery Switch Requirements

Battery switches must meet the following require-
ments.
•
The switch must be approved for marine use.
•
The switch should be a "make before break"
design to protect the charging system from a
no-load condition.
•
Switch amperage rating should be adequate for
the outboard it will be used on.
•
Use one battery switch for each outboard
installed.
•
Use the appropriate sized wire and terminals for
all connections.
•
Use AWG stranded copper wire.
INSTALLATION AND PREDELIVERY

Battery Switch Location

•
Always locate battery switch as close to the bat-
teries as possible.
•
Locate switch so that it cannot be accidently
bumped or switched.
•
Refer to the battery switch manufacturer's
installation instructions for specific information
related to the installation of switch.
•
Fasten all battery switches to solid surfaces.
•
Route wiring as directly as possible.
•
Support the battery switch as needed to prevent
abrasion.
•
Use appropriate wiring and connectors.
•
Seal all connections and terminals with liquid
neoprene or electrical sealer to prevent corro-
sion.
IMPORTANT:
Insulate all battery positive (+)
terminals to prevent shorting.

Battery Switch Operation

•
Select the primary battery for normal operation.
•
Secondary batteries should only be selected for
emergency starting.
•
ALL or BOTH switch position is for emergency
starting only.
Provide operator with the documentation sup-
plied by the battery switch manufacturer. Make
sure that the operator is informed of proper
battery switch operation.
IMPORTANT:
The negative (–) terminals of a
multiple 12-volt battery installation must be con-
nected together.
