ENGINE MANAGEMENT SYSTEM
- 334 -
DO: Install the secondary leads before
connecting the primary leads.
In the event the low voltage connection has
been made and the power applied, unwanted
secondary output might occur possibly resulting
in injury, damage the ignition component, and
test equipment
DO: Take care when working around the ignition
system.
The high voltage produced by the coil
secondary circuit can cause personal injury
and/or damage test equipment
DO: Proper handling and shipping methods need
to be in place to reduce the risk of damage due to
impact, moisture, or contamination
Damaged components can lead to premature
failure.
DO: Avoid unnecessary disconnecting and
connecting of the electrical components.
The electrical connections are not designed for
repeated connection and disconnection.
DO: Insure the low voltage connectors are
entirely seated and the locking mechanism is
engaged.
This prevents intermittent electrical connections
leading to an improper ignition system
operation.
DO: Use approved connector breakouts when
testing the ignition system.
Connector and/or component damage may
occur.
DO: Insure the appropriate seals are included in
the connector system.
Liquid intrusion into the terminal connection
area might occur causing an electrical
intermittent or short condition. In the event of
severe terminal corrosion, an open condition
might occur.
DO: Operate with gasoline based internal
combustion engines.
Other fuels or combustion designs may require
additional design considerations.
DO:The power feed line should be fused. This could protect the system in the event of an
electrical short
DO: The module heat sink and back plate must
not be used as a connection point when jump
starting the engine
The high level of voltage and current which the
module could be subjected to, could cause
module performance degradation or failure.
DO: Connection of the module back plate to
vehicle ground is desirable whenever possible
This greatly reduce potential ground loops and
acts as a heat transfer source from the module.
DO: The ignition system ground wire should be
kept as short as possible. And, when permissible,
should be grounded at the same engine block
position as the engine controller
This would greatly reduce the possible of
unwanted electrical ground loops.
DO: The electrical wiring to the ignition system
should be routed so that the conductors are
protected from excessive heat, damage, and
wear.
Helps prevent electrical intermittent, open or
shorted operating conditions.
DO: Ignition secondary leads should not be
routed with the ignition primary harness or any
other electrical harness.
Voltage spikes can be transmitted from the
secondary cables into other leads which are in
close. This could create a component
performance degradation or failure condition
