Precautions: 00-6
Short circuit check (Wire harness to ground)
1) Disconnect the negative (–) cable from the battery.
2) Disconnect the connectors/couplers at both ends of
the circuit to be checked.
NOTE
If the circuit to be checked branches to other
parts as shown, disconnect all connectors/
couplers of those parts. Otherwise, diagnosis
will be misled.
3) Measure resistance between terminal at one end of
circuit (“A” terminal in figure) and body ground. If
continuity is indicated, there is a short circuit to
ground between terminals “A” and “C”.
4) Disconnect the connector/coupler included in circuit
(coupler “B”) and measure resistance between
terminal “A” and body ground. If continuity is
indicated, the circuit is shorted to the ground
between terminals “A” and “B”.
Using The Multi-Circuit Testers
• Use the Suzuki multi-circuit tester set.
• Use well-charged batteries in the tester.
• Be sure to set the tester to the correct testing range.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
Using the testers
• Incorrectly connecting the (+) and (–) probes may
cause the inside of the tester to burnout.
• If the voltage and current are not known, make
measurements using the highest range.
• When measuring the resistance with the multi-circuit
tester (1), ∞ will be shown as 10.00 MΩ and “1”
flashes in the display.
• Check that no voltage is applied before making the
measurement. If voltage is applied the tester may be
damaged.
