16. BATTERY/CHARGING SYSTEM/ A.C. GENERATOR MXU 250R/300R VOLTAGE REGULATION TEST Connect a voltmeter across the battery Black terminals. Start the engine and gradually increase the engine speed. The battery terminal voltage should be within 1415 V. A.C. GENERATOR INSPECTION This test can be made without removing the stator from the engine. Disconnect the A.C. generator connector. Check the continuity between the yellow wires and ground. There should be continuity between the yellow wires and no continuity between each yellow wire and ground. Resistance (at 20°C): YellowYellow 1.62.5 A.C. Generator Bolts Set Plate A.C. GENERATOR/FLYWHEEL REMOVAL Remove the right crankcase cover. (Refer to the "WATER PUMP SHAFT REMOVAL" section in the chapter 12) Remove the pulser coil screws and then remove the A.C. generator wire set plate. Pulser Coil Screws Remove the A.C. generator bolts and then remove A.C. generator and pulser coil from right crankcase cover. When removing the pulser coil and stator, be careful not to damage them to avoid shorted or broken wire. Remove the oil through guide and spring. Oil Through Guide Spring 16-7
