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.

Note
l Adjust, using specification numbers 9H-15V (found
on headlight lens) with a “HOPPY” brand aimer or
equivalent.
