ELECTRICAL SYSTEM 9-11 GENERATOR NO-LOAD PERFORMANCE • Lift and support the fuel tank. (5-3) • Disconnect the generator coupler. W • Start the engine and keep it running at 5 000 r/min. • Using the multi-circuit tester, measure the voltage between W three lead wires. If the tester reads under the specified value, replace the gen- W erator with a new one. 09900-25008: Multi-circuit tester set Tester knob indication: Voltage (~) Generator no-load performance: 65 V and more at 5 000 r/min (When engine is cold) REGULATOR/RECTIFIER • Lift and support the fuel tank. (5-3) • Disconnect the regulator/rectifier couplers. • Measure the voltage between the lead wires using the multi circuit tester as indicated in the table below. If the voltage is not within the specified value, replace the regulator/rectifier with a new one.
