GENERATOR COIL RESISTANCE
Remove the left fuel tank side cover. (!7-5)
Disconnect the generator lead wire coupler.
Measure the resistance among the three lead wires.
If the resistance is not specified value, replace the stator coil
with a new one.
Also, check that the generator core is insulated.

GENERATOR NO-LOAD PERFORMANCE
Remove the left fuel tank side cover. (!7-5)
Disconnect the generator lead wire coupler.
Shift the transmission to the neutral position.
Start the engine and run it at 5 000 r/min.
Measure the AC voltage among the lead wires using the multi
circuit tester.
If the voltage is under the specified value, replace the AC gener-
ator with a new one.
