1J-4 Charging System:
Generator Inspection
B933H21A06003
Generator coil resistance
1) Disconnect the generator coupler (1).
2) Measure the resistance between the three lead
wires.
If the resistance is out of specified value, replace the
stator with a new one. Also, check that the generator
core is insulated properly.
NOTE
When making this test, it is not necessary to
remove the generator.
Special tool
: 09900–25008 (Multi-circuit tester set)

3) Connect the generator coupler (1).
No-load performance
1) Connect the tachometer onto the spark plug high-
tension cord.
2) Disconnect the generator coupler (1).
3) Start the engine and keep it running at 5 000 r/min.
4) Using the multi-circuit tester, measure the voltage
between three lead wires.
If the tester reads under the specified value, replace
the generator with a new one.
