 CHARGING SYSTEM
 CURRENT TEST
 Use a fully charged battery (12.8V min.)
   to check the charging system.
 Warm up the engine before taking readings.
 Connect an electric tester across the battery
 terminals.
 Disconnect the red wire from the fuse
 terminal and connect an ammeter between the
 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         A.C. Generator Connector
 Charging Current     7A min.       9A 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.
