Engine Stopping; Electrical System - Perkins 2206-E13 Operation And Maintenance Manual

SEBU8337
Engine exhaust contains products of combustion
which can be harmful to your health. Always start the
engine and operate the engine in a well ventilated
area. If the engine is started in an enclosed area,
vent the engine exhaust to the outside.
Note: The engine may be equipped with a device for
cold starting. If the engine will be operated in very
cold conditions, then an extra cold starting aid may
be required. Normally, the engine will be equipped
with the correct type of starting aid for your region
of operation.

Engine Stopping

Stop the engine according to the procedure in
the Operation and Maintenance Manual, "Engine
Stopping (Operation Section)" in order to avoid
overheating of the engine and accelerated wear of
the engine components.
Use the Emergency Stop Button (if equipped) ONLY
in an emergency situation. Do not use the Emergency
Stop Button for normal engine stopping. After an
emergency stop, DO NOT start the engine until the
problem that caused the emergency stop has been
corrected.
Stop the engine if an overspeed condition occurs
during the initial start-up of a new engine or an engine
that has been overhauled. This may be accomplished
by shutting off the fuel supply to the engine and/or
shutting off the air supply to the engine.
To stop an electronically controlled engine, cut the
power to the engine.

Electrical System

Never disconnect any charging unit circuit or battery
circuit cable from the battery when the charging unit
is operating. A spark can cause the combustible
gases that are produced by some batteries to ignite.
To help prevent sparks from igniting combustible
gases that are produced by some batteries, the
negative "−" cable should be connected last from the
external power source to the negative "−" terminal
of the starting motor. If the starting motor is not
equipped with a negative "−" terminal, connect the
cable to the engine block.
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 Practice

Typical example
(1) Starting motor to engine block
(2) Starting motor to battery negative
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
i02814681
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.
