Trouble DiagnosesNJSC0011Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspec-
tion Table.
+Before starting, inspect the fusible link.
+Use fully charged battery.
WITH IC REGULATORNJSC0011S01
SEL338V
NOTE:
+If the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque.)
+When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary, replace faulty
parts with new ones.
MALFUNCTION INDICATORNJSC0011S02The IC regulator warning function activates to illuminate ªCHARGEº warning lamp, if any of the following
symptoms occur while alternator is operating:
+Excessive voltage is produced.
+No voltage is produced.

CD AUTOCHANGERNJEL0385S06Testing Magazines and DiscsNJEL0385S06011. Confirm discs are installed correctly into the magazine (not upside down).
2. Visually inspect/compare the customer's discs with each other and other discs.
Identify any of the following conditions:
+Discs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
+Discs with rough or lipped edges.
+Discs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
+Discs with scratches, abrasions, or pits on the surface.
+Discs with grease/oil, fingerprints, foreign material.
+Discs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions.
Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
NOTE:
+Discs which are marginally out of specification (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automotive environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
+Use a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.
