MAINTENANCE, LUBRICATION AND SERVICE
ELECTRICAL SYSTEM
make sure the engines electrical system
has an engine-to-frame ground strap. All
ground connections should be tight and
free of corrosion.
DANGER
The engine uses high voltage to the
electronic unit injectors. DO NOT come in
contact with the unit injector terminals
while the engine is running. An electric
shock can cause an involuntary muscle
spasm and cause loss of balance and falls
leading to severe personal injury or death.
Electronic Engine Control
System
Tampering with the electronic system
installation can be dangerous and could
result in personal injury or death and/or
engine damage. It is very important to
take the proper precautions with the
electrical and electronic system when
charging the batteries, jump-starting or
performing electric welding on the
vehicle.
This vehicle is equipped with monitoring
features that may cause reduced power
or shutdown under certain conditions.
Monitoring and idling features can only
be programmed and/or changed with
electronic service tools and passwords.
Certain features, such as low oil
pressure, high coolant temperature or
low coolant level could cause the engine
power and/or vehicle speed to be limited
and the engine may also shut down.
DANGER
Failure to take necessary action when the
STOP tell-tale is on can ultimately result in
automatic engine shutdown and loss of
power steering assist. Vehicle crash can
occur, resulting in personal injury or death.
Wiring Harness / Cable and
Connector Protection
If corrosion is seen at any external ring-
type terminal connections, such as
those used at the starter, alternator,
chassis and/or engine grounds, etc.
Corrosion protectant must be applied to
the connection after disconnecting,
cleaning and reconnecting the ring
terminal. Additionally, corrosion
protectant should be applied to any
ring-type terminal connector following
any type of service procedure which
involved disconnecting/reconnecting the
ring terminals (such as component
replacement, troubleshooting, service
and repair, etc.).
To help protect your vehicle's external
high amperage electrical cables and
connections from corrosion due to the
effects of newer salts (calcium chloride
and magnesium chloride) on the
roadways, use an approved corrosion
inhibitor.
Coat all high amperage (positive and
ground) exposed electrical connections
at a minimum of every 6 months or,
whenever the connector has been
disassembled. The following list
contains the recommended connections
that should be liberally coated with the
corrosion inhibitor;
• Battery connections
• Battery main shut off switch
connections
• Maxi and/or Mega fuse connections
• All ground stud connections
• Electrical pass-thru connections
• All alternator connections
• All starter connections
• Intake preheater and preheater relay
connections
• Electrical power inverter connections
All connections should be cleaned and
free of previously applied inhibitors, oil,
dirt, dust or other contaminants prior to
application. Allow time for the product to
dry before use (drying time may vary
depending temperature, humidity, etc.)
