Battery Cable Requirements; Battery Switches And Multiple Batteries - BRP Evinrude E-TEC G2 150 HP Installation & Predelivery Manual

Battery Cable Requirements

Battery cables are NOT shipped with the engine.
Order standard or extended length battery cables
require an increased wire size. Refer to the follow-
ing table.
Cable Length
10 Ft. (3 m)
15 Ft. (4.6 m)
20 Ft. (6.1 m)
IMPORTANT:
Inadequate battery cables can af-
fect the performance of an outboard's high amper-
age start circuit and the cranking speed of the
outboard. DO NOT use aluminum wire cables. Use
ONLY AWG stranded copper wire cables.
Battery Switches and Multiple
Batteries
NOTICE
Insulate all battery positive (+) terminals to
prevent shorting.
NOTICE
The negative (–) terminals of a multiple
12-volt battery installation must be connected
together.
A multiple battery setup, including marine battery
selector switches, can provide flexibility in single
and dual outboard installations.
Refer to Battery and Switch Wiring Diagrams
(Typical) on p. 34 for battery connection options.
The battery selection function can be used for
emergency starting if a primary battery becomes
discharged.
The OFF position of the battery selector switch
can be used to minimize battery discharge during
periods of non-use.

Typical battery functions
Primary
•
Used as starting battery under normal operating
conditions.
•
Red (+) cable connected to battery 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 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 switch.
Secondary and accessory batteries are often
charged by an isolated battery charging circuit.
Refer to Auxiliary Battery Charging on p. 32.
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.
•
Switch amperage rating should be adequate for
the outboard it will be used on.
•
Use one battery switch for each outboard
installed.
•
Use appropriately sized wire and terminals.
•
Use AWG stranded copper wire.
Battery Switch Location
•
Locate battery switch as close to the batteries
as possible.
•
Locate switch so that it cannot be accidentally
bumped or switched.
•
Refer to the battery switch manufacturer's
installation instructions.
•
Fasten all battery switches to solid surfaces.
•
Route wiring as directly as possible.
