2004 STARTING & CHARGING SYSTEMS
Generators & Regulators - Endeavor
DESCRIPTION The charging system charges the battery with the generator output to keep the
battery charged at a constant level during varying electrical load. OPERATION Rotation of the excited field coil generates AC voltage in the stator. This alternating
current is rectified through diodes to DC voltage having a waveform. The average
output voltage fluctuates slightly with the generator load condition.
When the ignition switch is turned on, current flows in the field coil and initial
excitation of the field coil occurs. When the stator coil begins to generate power
after the engine is started, the field coil is excited by the output current of the stator
coil. The generator output voltage rises as the field current increases and it falls as
the field current decreases. When the battery positive voltage (generator S terminal
voltage) reaches a regulated voltage of approximately 14.4V, the field current is cut
off. When the battery positive voltage drops below the regulated voltage, the
voltage regulator regulates the output voltage to a constant level by controlling the
field current. In addition, when the field current is constant, the generator output
volta
ge rises as the en
gine s
peed increases. See Fig. 1
or Fig. 2

NOTE: See appropriate SELF DIAGNOSTICS article in ENGINE
PERFORMANCE to properly diagnose charging system.

For belt tension, see ADJUSTMENTS
.
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

generator output line and ground line in good condition?
If Yes, then go to next step. If No, check the generator output line and ground line.
8. Is the output current normal? If Yes, then go to next step. If No, then check the generator.
9. Is the regulated voltage normal? If Yes, then go to next step. If No, then check the generator.
10. Is the voltage drop in the generator output line normal? If Yes, then generator is normal. Check other systems. If No, then check the output line.
ON-VEHICLE TESTING GENERATOR OUTPUT LINE VOLTAGE DROP TEST Required special tools: MB991958: Scan Tool MUT-III Sub Assembly,
MB991824: V.C.I., MB991827: MUT-III USB Cable, MB991910: MUT-III Main
Harness A.
This test determines whether the wiring from the generator B-terminal to positive batter
y terminal
(includin
g the fusible link
) is in
good condition or not. See Fig. 3
