ELECTRICAL PARTS INSPECTION
1. Always disconnect the battery plug before inspecting or servicing electrical parts.
2. Pay sufficient attention when handling electronic parts.
(1) Never subject electronic parts, such as computers
and relays, to impact
(2) Never expose electronic parts to high temperature or
moisture
(3) Do not touch connector terminals, as they may be
deformed or damaged due to static electricity
3. Use a circuit multimeter that matches the object and purpose of measurement.
Analog type: This type is convenient for observing movement during operation and the operating
condition. Measured value is only a reference
Digital type: A fairly accurate reading is possible. However, it is difficult to observe operation or
movement.
(1) Difference between results of measurement with analog and digital types
∗ The results of measurements using the analog type and the digital type may be different.
Differences between the polarities of the analog type and the digital type are described below.
1) Analog circuit multimeter
Example of measurement result
Multimeter range: 1 kΩ
2) Digital circuit multimeter
Example of measurement result
Multimeter range: 2MΩ
