Generator Inspection

Generator Coil Resistance
1) Remove the left frame lower cover and secondary
gear case cover. Refer to "Exterior Parts Removal
and Installation in Section 9D (Page 9D-3)".
2) Disconnect the generator coupler (1).

3) 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.

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.
