Engine Electronics

Check the electrical wires daily for wires that
are loose or frayed. Tighten all loose electrical
connections before the engine is started. Repair all
frayed electrical wires before the engine is started.
See the Operation and Maintenance Manual for
specific starting instructions.

Grounding Practices

(1) Ground to battery
(2) Primary position for grounding
(3) Ground to engine block
(4) Ground to stating motor
Correct grounding for the engine electrical system
is necessary for optimum engine performance
and reliability. Incorrect grounding will result in
uncontrolled electrical circuit paths and in unreliable
electrical circuit paths.
Uncontrolled electrical circuit paths can result in
damage to the crankshaft bearing journal surfaces
and to aluminum components.
Engines that are installed without engine-to-frame
ground straps can be damaged by electrical
discharge.
To ensure that the engine and the engine electrical
systems function correctly, an engine-to-frame
ground strap with a direct path to the battery must be
used. This path may be provided by way of a direct
engine ground to the frame.
The connections for the grounds should be tight and
free of corrosion. The engine alternator must be
grounded to the negative "-" battery terminal with
a wire that is adequate to handle the full charging
current of the alternator.
The power supply connections and the ground
connections for the engine electronics should always
be from the isolator to the battery.
Engine Electronics
Tampering with the electronic system installation
or the OEM wiring installation can be dangerous
and could result in personal injury or death and/or
engine damage.
This engine has a comprehensive, programmable
Engine Monitoring System. The Engine Control
Module (ECM) has the ability to monitor the engine
operating conditions. If any of the engine parameters
extend outside an allowable range, the ECM will
initiate an immediate action.
The following actions are available for engine
monitoring control: WARNING, ACTION ALERT, and
SHUTDOWN.
Many of the parameters that are monitored by the
g02430157
ECM can be programmed for the engine monitoring
functions. The following parameters can be monitored
as a part of the Engine Monitoring System:
•
Intake Manifold Air Pressure
•
Intake Manifold Temperature
•
Coolant Temperature
•
Engine Oil Pressure
•
Engine Oil Temperature
•
Crankshaft Position
•
Camshaft Position
•
Fuel Pressure
•
System Voltage
The Engine Monitoring package can vary for different
engine models and different engine applications.
However, the monitoring system and the engine
monitoring control will be similar for all engines.
