.
TROUBLE SHOOTING 1. Is battery in good condition?
If Yes, then go to next step. If No, then charge or replace battery.
2. Is generator drive belt in good condition? If Yes, then go to next step. If No, then adjust belt tension or replace belt.
3. Does the generator malfunction light come on when the ignition switch is
turned on? If Yes, then go to next step. If No:
Check the ignition switch.
Check for burnt-out generator malfunction light.
Check the generator.
Check the generator malfunction light-related circuits.
4. Does the generator malfunction light go out after starting the engine? If Yes, then go to next step. If No, check the generator.
5. Is an oscilloscope available? If Yes, then go to next step. If No, then go to step 7 .
6. Does the oscilloscope show a normal wave pattern? If Yes, then go to next step. If No, then check the generator.
7. Turn the engine on and idle at 2500 RPM. Turn the headlights on with the
High Beams on. Be sure that there is voltage between generator terminal B and
the positive battery terminal of 0.5V or less. Check that the voltage between
the negative batter
y terminal and
generator bod
y is 0.5V or less. Are the

11. Immediately after setting the headlights to high beam and turning the heater
blower switch to the highest position, increase the engine speed to 2,500 RPM
and read the maximum current output value displayed on the ammeter. Limit
value: 70 percent of nominal current output.
12. The reading on the ammeter should be above the limit value. If the reading is
below the limit value and the generator output wire is normal, remove the
generator from the engine and check the generator.
13. Run the engine at idle speed after the test.
14. Turn the ignition switch to the LOCK (OFF) position.
15. Disconnect the engine tachometer or scan tool MB991958.
16. Disconnect the negative battery cable.
17. Disconnect the ammeter and voltmeter.
18. Connect the negative battery cable.
19. Run the engine for 10 minutes at an idle. REGULATED VOLTAGE TEST Required special tools:

-III Sub Assembly.
NOTE: The current output value will depend on the electrical
load and the temperature of the generator body.
NOTE: If the electrical load is small while testing, the specified
level of current may not be output even though the
generator is normal. In such cases, increase the
electrical load by leaving the headlights turned on for
some time to discharge the battery or by using the
lighting system in another vehicle, and then test again.
NOTE: The specified level of current also may not be output if
the temperature of the generator body or the ambient
temperature is too high. In such cases, cool the
generator and then test again.

Q: Is the abnormality in reception generated only within a certain range?
YES: Check that a poor reception is resolved.
NO: Go to Step 6.
STEP 6. Check the connection of the antenna plug and radio and CD
player.
Q: Is the antenna plug thoroughly connected to the radio and CD player?
YES: Go to Step 7.
NO: Thoroughly connect the antenna plug and the radio and CD player.
Check that a poor reception is resolved.
STEP 7. Check by replacing radio and CD player.
Q: Do the other radio and CD player work normally?
YES: Either repair or replace the original radio and CD player. Check that
a poor reception is resolved.
NO: Either re
pair or re
place the antenna assembl

NOTE: Two types of noise are addressed in this procedure,
multipath and fading noise. The frequency of FM waves
is extremely high. This makes them susceptible to
effects from geological formations and buildings. These
effects disrupt the broadcast signal and obstruct
reception in many ways.
Multipath noise is the echo that occurs when the
broadcast signal is reflected by a large obstruction
and enters the receiver with a slight time delay
relative to the direct signal (repetitious buzzing). A fading or buzzing noise may occur when the
broadcast beam is disrupted by obstructing objects
and the signal strength fluctuates within a narrow
range.
