1 Appearance
Harness is complete, no
loosening, damage, etc. Visual
inspection
Visually inspect whether the wiring
harness is complete, whether there are
loose lines, damage, etc.
Every
50,000 KM
The air around the wiring harness
circulates and is easy to dissipate
heat. There should be no spikes /
sharp objects, dry, dust-free Visual
inspection,
brush and
vacuum cleaner Visually inspect and clean the surface
with a brush or vacuum cleaner to
remove surface ash, impurities and
foreign matter
Every
50,000 KM
a) The ground point of the motor,
motor controller and chassis
ground should be coated with
conductive grease.
a) Visual
inspection
b) Multimeter
a) Visually check whether the
corresponding ground point still has
conductive grease
b) Use a multimeter and adjust it to the
resistance ohm range. A multimeter pen
touches the ground point of the motor /
motor controller. At the same time,
another pen touches the ground point of
the chassis to measure
Every
50,000 KM
2 Installation
b) The insulation resistance
between the ground point of the
motor and the motor controller
case and the chassis ground point
is not greater than 0.1
Ω
Visual
inspection and
touching with
hands
Visually and manually check the binding
of the wiring harness. For example,
check whether the bandage is lost, the
fixing clips are loose, the fixing glue is
detached, and the thread protective cover
is missing
Every
50,000 KM
The wiring harness should be tied
firmly and not loose. Vehicle
wiring and fastening must meet
the design requirements of the
vehicle manufacturer
Visual
inspection
Visually check whether the wiring
harness is bundled with low-voltage
wiring harness, gas, oil, water, etc.
Every
50,000 KM
The wiring harness cannot be
bundled with low-voltage wiring
harness, gas, oil, water, etc.
