CHECKING AND REPLACING ELECTRICAL
COMPONENTS
1. Visually inspect all electrical harnesses and cables
every month or at 200 hours of service life for the
following:
a. Damaged, cut or deteriorated harness loom
covering
b. Damaged, cut or abraded individual wires or cable
insulation
c. Exposed bare copper conductors
d. Kinked, crushed, flattened harnesses or cables
e. Blistered, soft, degraded wires and cables
f. Cracked, damaged, or badly corroded battery
terminal connections
g. Inspect all machine ground connections for
damaged terminals or excessive corrosion
h. Other signs of significant deterioration
If any of these conditions exist, evaluate the harness for
repair or replacement.
2. At the same service interval, visually inspect all
Controller Area Network (CAN) nodes and electrical
junction boxes for the following:
a. Damaged or loose connectors
b. Damaged or missing electrical clamps or tie straps
c. Excessive corrosion or dirt on the junction boxes
d. Loose junction box mounting hardware
If any of these conditions exist, address them
appropriately.
See Table 3-1
below for the following items.
3. Harness and battery cables operating in Zone C are
recommended to be replaced after 10,000 hours of
service life.
4. Harness and cables operating in Zone A and B with
high ambient temperatures and high duty circuits could
see electrical service life reduced by 25% to 40%. It is
recommended to replace these assemblies after 8,000
hours of service life.
5. Harness and cable assemblies operating in Zone D
and E, should expect a degrade of mechanical
properties and long term exposure to these cold
temperatures will negatively impact service life. It is
recommended for these electrical harnesses and cable
assemblies to be inspected to step 1 above as service
life may be more than 10,000 hours.
6. Harness and cable assemblies operating in salt water
climates could see a significant reduction in service life.
Therefore it is recommended for these electrical
harnesses and cable assemblies to be inspected to
step 1 above as service life may be more than 8,000
hours.
Table 3-1 Climate Zone Classification:
DANGER
Electrical Shock Hazard!
Ensure that the battery cables are disconnected from the
batteries before loosening any electrical connections.
