AC GENERATOR NO-LOAD PERFORMANCE
Remove the left frame cover. (
Disconnect the stator coil lead wire coupler.
Start the engine and run it at 5 000 r/min.
Measure the AC voltage between the lead wires of the genera-
tor using the multi circuit tester. If the voltage is under the speci-
fied value, replace the AC generator with a new one.

Tester knob indication: Voltage (~)
AC generator no-load performance
Standard:
More than 55 V (AC) at 5 000 r/min (DR-Z400)
More than 75 V (AC) at 5 000 r/min (DR-Z400E)
REGULATOR/RECTIFIER
Remove the left frame cover. (
Disconnect the regulator/rectifier coupler.
Measure the voltage between the terminals using the multi cir-
cuit tester, as indicated in the table below. If the voltage is not
within the specified value, replace the regulator/rectifier with a
new one.
