4. Connect a clamp-type DC test ammeter with a range of 0-150A to the
generator B terminal output wire.
5. Connect a digital-type voltmeter between the generator B terminal and the
positive battery terminal. (Connect the positive lead of the voltmeter to the B
terminal, and then connect the negative lead of the voltmeter to the positive
battery cable.)
6. Reconnect the negative battery cable.
7. Connect an engine tachometer or scan tool MB991958.
8. Leave the hood open.
9. Start the engine.
10. With the engine running at 2500 RPM, turn the headlights and other lights on
and off to adjust the generator load so that the value displayed on the ammeter
is slightly above 30A. Read the voltmeter. Voltage reading at or below limit
value means voltage drop between generator and batter is OK. There should be
a maximum voltage of 0.3V.
11. If the value displayed on the voltmeter is above the limit value, there is
probably a malfunction in the generator output wire. Check the wiring between
the
generator B terminal and the
positive batter
y terminal
(includin
g fusible
NOTE: The way of disconnecting the generator output wire and
of connecting the ammeter is possibly not found the
problem that the output current is dropping due to the
insufficient connection between terminal B and the
output wire.
NOTE: When the generator output is high and the value
displayed on the ammeter does not decrease to 30A,
set the value to 40A. Read the value displayed on the
voltmeter at this time. In the case the limit value
becomes maximum 0.4V. Adjust the engine speed by
gradually decreasing it until the value displayed on the
ammeter is 30A. Take a reading of the value displayed
on the voltmeter at this time

Battery. Generator drive belt tension. Fusible link. Abnormal noise from the generator while the engine is running.
2. Turn the ignition switch to the LOCK (OFF) position.
3. Disconnect the negative battery cable.
4. Connect a clamp-type DC test ammeter with a range of 0-150A to the
generator B terminal output wire.
5. Connect a voltmeter with a range of 0-20V between the generator B terminal
and ground. (Connect the positive lead of the voltmeter to the B terminal, and
then connect the negative lead of the voltmeter to ground.)
6. Connect the negative battery cable.
7. Connect an engine tachometer or scan tool MB991958.
8. Leave the hood open.
9. Check to be sure that the reading on the voltmeter is equal to the battery
positive voltage.
10. After turnin

ghts, start the en
gine.
WARNING:Never use clips to connect the line. Loose
connections (for example, using clips) will lead
to a serious accident because of high current.
NOTE: If the voltage is 0 V, the cause is probably an open
circuit in the wire or fusible link between the generator
B terminal and the battery positive terminal or
malfunctioning voltmeter.
NOTE: Because the current from the battery will soon drop
after the engine is started, the next step should be
carried out as quickly as possible in order to obtain the
maximum current output value.
