Generator Inspection - Suzuki LT-A400 Service Manual

1J-4 Charging System:

Generator Inspection

Generator Coil Resistance
1) Remove the left side cover and left footrest
mudguard. Refer to "Exterior Parts Removal and
Installation in Section 9D (Page 9D-3)".
2) Connect the tachometer to the spark plug high
tension cord.
3) Disconnect the generator lead wire coupler (1).
4) 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.

No-load Performance
1) Remove the left side cover and left footrest
mudguard. Refer to "Exterior Parts Removal and
Installation in Section 9D (Page 9D-3)".
2) Connect the tachometer to the spark plug high-
tension cord.
3) Disconnect the generator lead wire coupler (1).
4) Start the engine and keep it running at 5 000 r/min.
5) 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.
