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.

Power steering is only operable when the engine is running. If the engine
is off or if the power steering system is inoperable, you can still steer, but
it requires more physical effort. If the steering feels stiffer than usual
during normal driving or the steering vibrates, consult an A ...
