16. BATTERY/CHARGING SYSTEM GRAND DINK 125/150 CHARGING SYSTEM CURRENT TEST Use a fully charged battery (12.8V min.) to check the charging system. Warm up the engine after connecting a fully charged battery. Connect an electric tester across the battery terminals. Disconnect the red wire from the fuse terminal and connect an ammeter between the Red Wire red wire lead and the fuse terminal. Attach a tachometer to the engine. Start the engine and gradually increase the engine speed to measure the limit voltage and current. Limit Voltage/Current: 1415V/0.5A max. (5000rpm max.) If the limit voltage is not within the specified range, check the regulator/rectifier. PERFORMANCE TEST Engine Speed 2500rpm 5000rpm Charging Current 6A min. 8A min. When measuring the charging current, disconnect the black wire from the regulator/rectifier wire coupler. If the readings do not meet the specified values, check the regulator/rectifier. A.C. GENERATOR INSPECTION This test can be made without removing the stator from the engine. Disconnect the yellow wire from the auto bystarter. Remove the frame center cover. 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: YellowYellow 0.61.6 A.C. Generator Connector 16-5
