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:
- Damaged, cut, or deteriorated harness loom
covering
- Damaged, cut, or abraded individual wires or cable
insulation
- Exposed bare copper conductors
- Kinked, crushed, or flattened harnesses or cables
- Blistered, soft, or degraded wires and cables
- Cracked, damaged, or badly corroded battery
terminal connections
- Inspect all machine ground connections for
damaged terminals or excessive corrosion
- 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:
- Damaged or loose connectors
- Damaged or missing electrical clamps or tie straps
- Excessive corrosion or dirt on the junction boxes
- Loose junction box mounting hardware
If any of these conditions exist, address them
appropriately.
3. Harness and battery cables operating in Zone C
(Table 3-1.
) 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.
DANGER
Electrical Shock Hazard
Ensure that the battery cables are disconnected from the
batteries before loosing any electrical connections.
