Typical example
(5) Ground to the battery
(6) Ground to the engine block
(7) Primary position for grounding
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 Engine Monitoring
System. An electronic control governor can be
installed onto the engine. The electronic control
governor can monitor certain engine operating
conditions. If certain engine parameters extend
outside an allowable range, the electronic control
governor will initiate an immediate action.
The following monitored engine operating conditions
have the ability to limit engine speed and/or the
engine power:
• Engine Coolant Temperature
• Engine Oil Pressure
g02343617
• Engine Speed
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.
Note: Many of the engine control systems and
display modules that are available for Perkins
Engines will work in unison with the Engine
Monitoring System. Together, the two controls will
provide the engine monitoring function for the specific
engine application.
