          16. BATTERY/CHARGING SYSTEM

 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      Red Wire
 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          6000rpm
 Charging Current 1.3A min.        2.0A min.
 When measuring the charging current,
   disconnect the wire from the
   regulator/rectifier wire coupler.
 If the readings do not meet the specified
 values, check the regulator/rectifier.
                                                               A.C. Generator Connector
 A.C. GENERATOR INSPECTION
  
      Inspect with the engine installed.

 Remove the met-in box. ( 2-4)
 Disconnect the A.C. generator connector.
 Measure the resistances between the charging
 coil terminals (white­blue/yellow) and
 lighting coil terminals (yellow­green).
 Resistances:
 Charging coil white­green 0.21.2
 Lighting coil yellow­green 0.31.0
