ELECTRICAL TROUBLESHOOTING TOOLS
Test Light
The test light, as shown in the figure, uses a
12V
bulb. The
two lead wires should be connected to probes.
The test light is used for simple voltage checks and for
checking for short circuits.
f;;;;\
1.4w OR 3.4w
Caution
When checking the control unit, never use a bulb
over 3.4W.
CAUTION
Jumper Wire
The jumper wire is used for testing by shorting across
switch terminals and ground connections.
Caution
Do not connect a jumper wire from the power
source line to a body ground; this may cause
burning or other damageto harnesses or electronic
components.

The DC voltmeter is used to measure circuit voltage. A
voltmeter with a range of 15V or more is used by connect-
ing the positive (+) probe (red lead wire) to the point where
voltage is to be measured and the negative (-) probe
(black lead wire) to a body ground.
Diagnosis Connector
Insert the probe into the service hole when connecting a
jumper wire to the diagnosis connector.
Caution
Do not insert the jumper wire probe into the diagno-
sis connector terminal, which may damage the
terminal.

Ohmmeter
The ohmmeter is used to measure the resistance between
two points in a circuit and also to check for continuity and
diagnosis of short circuits.
Caution
Do not attempt to connect the ohmmeter to any
circuit to which voltage is applied; this may burn or
otherwise damage the ohmmeter.
