Electrical System; Battery Cables; Batteries And Connections - Volvo 5.0OSiE-J Operator's Manual

Electrical System

The engine's electrical system features cranking, charging, ignition, and trim/tilt circuits. A battery and all
necessary wiring provide power.
WARNING! Do not expose the battery to electrical sparks or an open flame. Do not use jumper cables
and a booster battery to start the engine. Remove the battery from the boat to recharge. Do not re-
charge the battery in the boat.
NOTICE! The battery terminal connections must always be insulated. If the battery mounting system does not
cover the connections, install protective covers. This will help prevent shorting or arcing at the battery
terminals.
NOTICE! If electrical connections are reversed, or wires are disconnected when the key switch is ON or the engine
is running, sensitive electrical components may be immediately damaged. Do not turn off the main bat-
tery switch until the engine has stopped.

Battery Cables

The following are the minimum specifications for multi-
strand copper cables from the motor to the battery for
all models. The maximum length is 20 feet per cable,
regardless of diameter.
•
0 to 10 ft. (3.05 m) require a 1/0 AWG (80 MWG)
cable.
•
10 to 15 ft. (3.05 to 4.6 m) require a 2/0 AWG
(100 MWG) cable.
•
15 to 20 ft. (4.6 to 6.1 m) require a 3/0 AWG (120
MWG) cable.
NOTICE! Do not use aluminum core battery cables.
Failure to use battery cables of recom-
mended gauge and material could result in
poor starting and electrical component
damage.

Batteries and Connections

Battery Requirements:
All EFI engines ................... 650 CCA non-deep cycle
NOTICE! Do not use deep cycle batteries on EFI en-
gines. A deep cycle battery, while it may
have enough cold cranking amps (CCA),
will cause problems with EFI engines. The
correct starting battery for all Volvo Penta
EFI engines is a standard marine battery
with a minimum of 650 CCA and a minimum
of 135 minutes reserve capacity.
