ELECTRICAL TROUBLESHOOTING TOOLS
Jumper Wire
The jumper wire is used for testing by short-circuiting switch terminals and to verify the condition of ground connections.
CAUTION
Do not connect the jumper wire between a power source and a body ground. Doing so may cause burning or other damage to harnesses and electronic components.
Voltmeter
The DC voltmeter is used for measurement of circuit voltage. A voltmeter with a range of 15V or more must be used. It is used by connecting the positive (+) probe (red lead) to the point where voltage is to be measured and connecting the negative (-) probe (black lead) to a body ground.
Ohmmeter
The ohmmeter is used to measure the resistance between two points in a circuit, to check for continuity, and to diagnose short circuits.
CAUTION
Never connect the ohmmeter to any circuit to which voltage is applied. Doing so may burn or otherwise damage the ohmmeter.
GENERAL PRECAUTION
Before Disconnecting Battery Cables
The optional audio unit has an anti-theft function that is activated when the battery power is disconnected. Obtain the code number and deactivate the audio anti-theft system before disconnecting the battery. (Refer to page T-113.)
