CHAPTER 3 ENGINE
3.12.6 Ignition Coil
3.12.6.1 Description and Working Principle
This coil provides energy to the spark plug in the
combustion chamber. The coil itself doesn't have a
driver. The high voltage tower of the coil is
connected to the spark plug using a high voltage
cable assembly.
3.12.6.2 Installation requirements
● The vehicle frame provides the mounting
surface and mounting holes.
● Never route the coil wire with the same bundle
as the Crank sensor wires. There is around 200 V
peak potential between wire and engine ground.
This voltage potential could cause a noise on
sensor cables.
3.12.6.3 Do's and Don'ts
DO NOT: Install the low voltage connectors with
the power applied.
DO NOT: Use a screw driver to asset in removing
secondary boots from the secondary tower. Use
tools designed for secondary removal.
DO NOT: Use parts that have been dropped or
display physical damage.
DO NOT: Scratch or apply any non approved
material to the surface of the high voltage tower
which mates with the high voltage secondary
leads.
DO NOT: Strike any part of the ignition system with
a tool or other object.
DO NOT: Permit paint or other sprayed materials
to be sprayed onto the electrical connectors.
DO NOT: Support the ignition system by the wiring
harness or plug wire.
ACTION
BUCK 450 SERVICE MANUAL 20.0
REASON
This might cause an unwanted secondary firing,
possibly leading to personal injury.
It is possible to damage a secondary lead in such a
manner that creates an electrical path to outside the
system permitting improper system operation misfire,
or even possible personal injury if arcing occurs.
Damaged components can lead to premature failure.
This can jeopardize the seal integrity of the mating
surfaces which in turn can create a secondary high
voltage leak path.
This can lead to physical damage which can cause a
system malfunction or failure.
Insulating type sprays can create a high resistance or
open connection. And, a conductive type spray can
create an electrical short condition.
These leads are not designed to support the weight of
the ignition system. It can create a poor electrical
connection Or become disconnected allowing the
system to fall and be subjected to physical damage
