HOW TO USE THIS SECTION
Information regarding removal and installation of electrical equipment is given in SECTION S.

ELECTRICAL TROUBLESHOOTING TOOLS
Test Light
The test light, as shown in the figure, uses a battery voltage
bulb. The two leads should be connected to probes. The test
light is used for simple voltage checks and to check for open
circuits.
Caution
l When checking the control unit, never use a bulb
over 3.4W.
Jumper Wire
The jumper wire is used for testing by short-circuiting switch
terminals and for verifying the condition of ground connections.
Caution
l Do not connect the jumper wire between a power
source line and body ground because this may
cause burning or other damage to harnesses or
electronic components.
The DC voltmeter is used for measuring circuit voltage. A volt- q Voltmeter
meter with a range of 15V or more is used by connecting the
positive (+) probe (red lead) to the point where voltage is to
be measured, and the negative (-) probe (black lead) to the
body ground.
Ohmmeter
The ohmmeter is used to measure the resistance between two
points in a circuit, and is also used to check for continuity and
diagnosis of short circuits.
Caution
l Do not attempt to connect the ohmmeter to any cir-
cuit to which voltage is applied because this may
burn or otherwise damage the ohmmeter.
