STARTING AND CHARGING SYSTEM (X22SE 2.2L)

Continuity of Series Coil

Check for continuity between terminals S and M.
Replace, if there is no continuity (i.e., coil is 
disconnected).

Continuity of Contacts

With the plunger faced downward, push down the 
magnetic switch. In this state, check for continuity 
between terminals B and M. Replace, if there is no 
continuity (i.e., contacts are faulty).

065RW018

Pinion

Check if the pinion rotates smoothly in drive direction by 
hand, or if it is locked when it is rotated in reverse. If not, 
replace the pinion.

Characteristic Test

For easily confirming the characteristics, conduct the 
noload test as follows:
Rating as short as 30 seconds requires rapid testing.
Fix the starter on the test bench, and wire as shown in 
illustration. When the switch is closed,  the current flows 
and the starter runs under no load. At this time, 
measure current, voltage and speed  to check if they 
satisfy the standard.

Charging System

General Description

The charging system is an IC integral regulator charging 
system and its main components are connected  as 
shown in illustration.
The regulator is a solid state type and it is mounted 
along with the brush holder assembly inside  the 
generator installed on the rear end cover.
The generator does not require particular maintenance 
such as voltage adjustment.  The rectifier connected to 
the stator coil has eight diodes to transform AC voltage 
into DC voltage.
This DC voltage is connected to the output terminal of 
generator.

General On–Vehicle Inspection

The operating condition of charging system is indicated 
by the charge warning lamp. The warning lamp comes 
on when the starter switch is turned to “ON" position.  
The charging system operates normally if the lamp goes 
off when the engine starts.
If the warning lamp shows abnormality or if 
undercharged or overcharged battery condition is 
suspected, perform diagnosis by checking the charging 
system as follows:

1. Check visually the belt and wiring connector.

STARTING AND CHARGING SYSTEM (X22SE 2.2L)

2. With the engine stopped, turn the stator switch to 

“ON" position and observe the warning lamp.
If lamp does not come on:
Disconnect wiring connector from generator, and 

ground the terminal “L" on connector side.
If lamp comes on:
Repair or replace the generator.

Removal

1. Disconnect battery ground cable.

2. Move drive belt tensioner to loose side using wrench 

then remove drive belt.

3. Disconnect terminal “B" wiring connector and 

connector.

4. Remove generator bracket (1), (2) and remove 

generator assembly.

1. Disconnect battery.

2. Close off connecting cable from alternator terminal 

“B+".

3. Set ammeter (measuring range 100A) in 

disconnected line.

4. Connect controllable load resistor to battery 

terminal.

5. Set resistor in front of connection to “0"; connect first 

to battery, then to resistor.

6. Connect tachometer.

7. Connect oscilloscope according to manufacturer's 

instructions.

8. Connect battery.

9. Start engine and read off resulting current at various
