Generator Inspection

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, be sure that the
battery is in fully charged condition.

No-load Performance
1) Disconnect the generator coupler (1).
2) Start the engine and keep it running at 5 000 r/min.
3) 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.
