Electrical Equipment
The electrical equipment of your
STEYR MOTORS GmbH Marine engine
primarily consists of an alternator with
transistorized voltage regulator, battery and all necessary connecting cables and leads.
NOTE:
24 V on board system requires a specified DC/DC-converter to supply the entire Engine
Management System EMS with 12 V. For detailed instructions consult your authorized
STEYR MOTORS GmbH Service Partner.
Alternator
The alternator is driven via a
poly-v-belt
to charge the battery at all engine speeds. Output at idle speed is limited to
low amperage/voltage values and will rise with an engine speed to maximum output above 3000 revs.
Optional:
Alternators are available with different outputs and voltages.
Battery
FOR ALL 4 CYL. MARINE ENGINES
Use a 12-volt battery with a cold testing circuit of 450 A at -18 °C and a
minimum capacity of 92 Ah
at 27 °C, to
ensure the supply of the electric and electronic components at all operating conditions.
FOR ALL 6 CYL. MARINE ENGINES
Use a 12-volt battery with a cold testing circuit of 650 A at -18 °C and a
minimum capacity of 115 Ah
at 27 °C, to
ensure the supply of all electric and electronic components.
ATTENTION: * Do not use jumper cables and a booster battery to start engine. Remove battery
from boat and recharge.
- WRONG CONNECTION WILL DESTROY ELECTRONIC SYSTEM -
* Do not charge battery in boat. Fumes vented during battery charging can lead to an
explosion.
* Battery electrolyte is a corrosive acid and should be handled with care.
If electrolyte is spilled or splashed on any part of the body, immediately flush the exposed
area with liberal amounts of water and obtain medical aid as soon as possible.
High resistance in the charging circuit can seriously affect the operation of the electrical system. Unless there is
definite malfunction in the electrical system, high resistance is sometimes caused by corroded or loose connections.
Wherever practical, the electrical connections on your engine have been sealed. However, we recommend that you
make periodic inspections to ensure clean, tight connections throughout the electrical system.
NOTE:
It is important that the battery connections are correct. The negative battery cable must be
attached to the negative terminal (
–
) on the battery and the engine’s positive cable must be
attached to the positive terminal (
+
) on the battery.
If these connections are reversed, the
regulating unit may be immediately damaged.
Inspect your battery at regular intervals for specific gravity (state of charge), individual cell water level, cleanliness
and clean, tight connections.
If the battery has become discharged for no apparent reason, check all electrical system components for malfunction,
or a switch left in ON position prior to installing recharged battery.
