in AM and FM modes with
accessories on (switch
pops and motor noise).1. Poor audio unit ground
2. Antenna
3. Accessory ground
4. Faulty accessory1. Check audio unit ground.
2. Check antenna.
3. Check accessory ground.

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.

Inspection=NJEL0221AUDIO UNITNJEL0221S01All voltage inspections are made with:
+Ignition switch ON or ACC
+Audio unit ON
+Audio unit connected (If audio unit is removed for inspection, supply a ground to the case using a jumper
wire.)
ANTENNANJEL0221S02Using a jumper wire, clip an auxiliary ground between antenna and body.
+If reception improves, check antenna ground (at body surface).
+If reception does not improve, check main feeder cable for short circuit or open circuit.

Window Antenna RepairNJEL0250ELEMENT CHECKNJEL0250S011. Attach probe circuit tester (in ohm range) to antenna terminal
on each side.
If an element is OK, continuity should exist.
If an element is broken, no continuity should exist. Go to step
