NO:

 Check the generator output line and ground line.

STEP 8.

Q:Is the output current normal? (Refer to Charging System

- On-vehicle Service - Output Current Test P.16a-8.)

YES:

 Go to Step 9.

NO:

 Check the generator related circuit. If the circuit

is normal, replace the generator (Refer to Charging

and Instllation P.16a-13).

STEP 9.

Q:Is  the  regulated  voltage  normal?  (Refer  to  Charging

System - On-vehicle Service - Regulated Voltage Test.)

YES:

 Go to Step 10.

NO:

 Check the generator related circuit. If the circuit

is normal, replace the generator (Refer to Charging

This  test  determines  whether  the  wiring  from  the
generator "B" terminal to the positive battery terminal
(including the fusible link) is in good condition or not:

Battery posts, terminals and related accessories
contain lead and lead compounds. WASH HANDS
AFTER HANDLING.

1.

Always  be  sure  to  check  the  following  before  the
test.

Generator installation

Generator  drive  belt  tension  (Refer  to  GROUP
00, General - Maintenance Service - Drive Belts
(For Generator, and Air Conditioning) (Check) P.
00-58.)

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  -  150  A  to  the  generator  "B"  terminal
output wire.

NOTE: 

The way of disconnecting the generator

output wire and of connecting the ammeter is
possibly not found the problem that the output

16a-6

CHARGING SYSTEM

ON-VEHICLE SERVICE

current is dropping due to the insufficient
connection between terminal "B" and the 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  2,500  r/min,  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 30 A.
Read the voltmeter. Voltage reading at or below
limit value means voltage drop between generator
and battery is OK.

Limit value: maximum 0.3 V

NOTE: 

When the generator output is high and

the value displayed on the ammeter does not
decrease to 30 A, set the value to 40 A. Read
the value displayed on the voltmeter at this
time.In this case the limit value becomes

maximum 0.4 V.Adjust the engine speed by
gradually decreasing it until the value
displayed on the ammeter is 30 A. Take a
reading of the value displayed on the voltmeter
at this time.

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 battery
terminal (including fusible link).
If a terminal is not sufficiently tight or if the harness
has become discolored due to overheating, repair
and then test again.

12.

After the test, run the engine at idle.

13.

Turn off all lights and turn the ignition switch to the
"LOCK" (OFF) position.

NOTE: 

Vehicles for Canada, the headlight,

taillight, etc. remain lit even when the
lighting switch is in "OFF" position.

14.

Disconnect  the  engine  tachometer  or  scan  tool
MB991958.

15.

Disconnect the negative battery cable.

16.

Disconnect the ammeter and voltmeter.

17.

Connect the negative battery cable.

18.

Run the engine for 10 minutes at an idle.

This  test  determines  whether  the  generator  outputs
normal  current.  For  best  results,  use  a  charging
system tester. If not available, follow the steps below.

Battery posts, terminals and related accessories
contain lead and lead compounds. WASH HANDS
AFTER HANDLING.

1.

Before  the  test,  always  be  sure  to  check  the
following.

Generator installation

Battery (Refer to GROUP 54A, Chassis Electrical
- Battery - On-vehicle Service - Battery Check P.
54Aa-2.)

NOTE: 

The battery to be used should be

slightly discharged. The load in a fully-
charged battery will be insufficient and the
test may not be able to be carried out
correctly.

Generator  drive  belt  tension  (Refer  to  GROUP
00, General - Maintenance Service - Drive Belts
(For  Generator,  Power  Steering  Pump  and  Air
Conditioning) (Check) P.00-58.)

Fusible link

Abnormal  noise  from  the  generator  while  the
engine is running.

2.

Turn  the  ignition  switch  to  the  "LOCK"  (OFF)
position.
