BATTERY

• Check and clean the battery terminal connections
and insure the connections are tight.
• Check the battery for any cracks or damage to the
case.
• Check the Positive and Negative battery cables for
any corrosion build up, rubbing or chaffing, and
check ground connections on chassis, to insure they
are tight.

ECM CHECKS

• Check the mounting bracket for the EControls ECM,
for cracks or breaking.
• Check the controller mounting bracket, securing
bolts to insure they are securely fastened.
• Check the rubber
deterioration.
• Check the electrical connector and insure the
connector is securely attached, locked and the
secondary lock is in position. Check the connector
for any corrosion in the connector, or on the pins.
Clean if observed.

WIRE HARNESS CHECKS

• Check the wire harness routing, under the hood, to
insure the main harness and injector harness have
not come into contact with any rotating devices, hot
surfaces, or have come loose from their securing
points, and are hanging in an unsafe location.
• Check all wire ties and / or clamps used to secure the
harness for cracking, splitting, or breakage, replace
if necessary.
• Check the harness routing and insure the harness is
securely attached to the frame and protected from
any hot surfaces, rotating devices or road debris,
repair any unsafe condition.

SENSORS

• While inspecting the wire harness connector for each
sensor, check for any damage to the sensor.
• If the sensor is retained by threads or by fasteners,
insure the retaining device is fully secured.
IGNITION SYSTEM
• Check ignition coil and spark plug cables for
hardening, cracking, chaffing, separation, split boot
covers and properly fitted.
• Replace spark plugs at the proper intervals, as
prescribed in the recommended maintenance.
• Check to make sure all electrical components are
fitted securely.
isolators for cracks
MISCELLANEOUS ELECTRICAL
• Check the instrument panel to insure all warning
lights are functioning, MIL, oil pressure and
temperature gauges are registering
• Check the ignition switch and electrical connectors to
insure the connections are fully seated and locked
and the tumbler mechanism is working properly
RECOMMEDNED MAINTENANCE
The maintenance
manufacturers recommended maintenance intervals to
maintain proper engine/equipment function. Specific
