3．DOs and DONTs
Ignition Coil Handing
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.
DO NOT: Pierce or probe the secondary
leads.
DO NOT: Operate without the spark plug
attached.
DO NOT: Share ignition component wiring with
other components, Dedicated wiring is required .
DO NOT: Apply voltage to the ignition system
other than vehicle system voltage for testing
purposes.
ENGINE MANAGEMENT SYSTEM
Action
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
This creates an electrical path to outside the
system permitting improper system operation,
misfire, or even possible personal injury if arcing
occurs.
If a technician or mechanic comes in contact
with the high voltage generated during
operation, personal injury may occur. Or, if the
engine is operated under this condition,
unburned fuel may fill the converter area
creating a potential hazard
This prevents electrical cross talking between
components which can lead to component
malfunction.
This can cause reduced performance or an
electrical malfunction of the ignition system.
