MULTI-CIRCUIT TESTER
• 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 TESTERS
• Use the Suzuki multi-circuit tester (09900-25008).
• Use well-charged batteries in the tester.
• Be sure to set the tester to the correct testing range.
Using the tester
• 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.
• Reset the pocket tester to 0
Ω
before measuring each resis-
tance or after changing the resistance range.
• When measuring the resistance with the multi-circuit tester, also
measure the resistance with no-load. Sub-tract that resistance
from the resistance measured under load in order to get the
true resistance.
(Measured
–
(No-load
= (True resistance)
resistance) resistance)
• When measuring the resistance with the multi-circuit tester,
∞
will be shown as 10.00M
Ω
and “1” flashes in the display.
• Check that no voltage is applied before making the measure-
ment. If voltage is applied, the tester may be damaged.
• After using the tester, turn the power off.

09900-25008: Multi-circuit tester
NOTE:
* When connecting the multi circuit tester, install fine copper wires
(O.D is below 0.5 mm) to the back side of the lead wire coupler
and connect the probes of tester to them.
* Use a fine copper wire, the outer diameter being below 0.5
mm, to prevent the rubber of the water proof coupler from dam-
age.
