•Using ohmmeter, check for continuity between slip rings of
rotor. If there is no continuity, replace rotor.

Brush and brush holder
Check each brush for wear by measuring its length as shown. If
brush is found worn down to service limit, replace brush.
Exposed brush length “a”
Standard : 10.5 mm (0.413 in.)
Limit : 1.5 mm (0.059 in.)
Rectifier
•Positive Rectifier
a) Using an ohmmeter, connect one tester probe to the “B”
terminal (1) and the other to each rectifier terminal (2).
b) Reverse the polarity of the tester probes and repeat step a).
c) Check that one shows continuity and the other shows no
continuity. If there is continuity, replace the rectifier.
•Negative Rectifier
a) Using an ohmmeter, connect one tester probe to each neg-
ative terminal (1) and the other to each rectifier terminal (2).
b) Reverse the polarity of the tester probes and repeat step a).
c) Check that one shows continuity and the other shows no
continuity. If there is continuity, replace the rectifier.

For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in FOREWORD of this manual.
