ELECTRICAL TROUBLESHOOTING TOOLS
Test Light
The test light, as shown in the figure, uses a 12V bulb.
The two leads should be connected to probes. The
test light is used for simple voltage checks and to
check for short circuits.
Caution
When checking the control unit, never use a
bulb over 3.4W.
69G15X-002
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 line and body ground, because
doing so may cause burning or other damage
to harnesses or electronic components, etc.
61G15X-002
Voltmeter
The DC voltmeter is used for measurement of circuit
voltage. A voltmeter with a range of 15V or more is
used. It is used by connecting the positive (+) probe
(red lead) to the point where voltage is to be meas-
ured and connecting the negative (-) probe (black
lead) to the body ground.
