Mazda 6 Service Manual: Electrical troubleshooting tools
Jumper wire
- A jumper wire is used to create a temporary circuit. Connect the jumper wire between the terminals of a circuit to bypass a switch.
Caution
- Do not connect a jumper wire from the power source line to a body ground. This may cause burning or other damage to wiring harnesses or electronic components.
Voltmeter
- The DC voltmeter is used to measure circuit voltage. A voltmeter with a
range of 15 V or more
is used by connecting the positive (+) probe (red lead wire) to the point where voltage will be measured and the negative (-) probe (black lead wire) to a body ground.
Ohmmeter
- The ohmmeter is used to measure the resistance between two points in a circuit and to inspect for continuity and short circuits.
Caution
- Do not connect the ohmmeter to any circuit where voltage is applied. This will damage the ohmmeter.
