 MAIN HARNESS CIRCUIT INSPECTION
 Remove the front covers. ( 2-2)
 Remove the regulator/rectifier 4P coupler and
 check for continuity between the wire harness
 terminals according to the following :
      Item (Wire Color)           Judgment
  Between battery (red)       Battery has
  and engine ground           voltage
  Between ground (green)      Continuity exists
  and engine ground
  Between lighting wire
  (yellow) and engine
  ground (Remove the          A.C. generator
  resistor coupler and auto   stator has
  bystarter coupler and       resistance
  turn the lighting switch
  OFF for inspection)
  Between charging coil       A.C. generator
  (white) and engine          stator has
  ground                      resistance


                                                                  Red        Yellow
 REGULATOR/RECTIFIER INSPECTION
 If the main harness terminals are normal,
 check the regulator/rectifier coupler for loose
 connection and measure the resistances
 between the regulator/rectifier terminals.
 · Do not touch the tester probes with
      your finger because human body has
      resistance.
    · Use the following specified testers for
      accurate testing. Use of an improper
      tester in an improper range may give
      false readings.                                                    White        Green
      - Kowa Electric Tester
      - Sanwa Electric Tester
      - Kowa Electric Tester TH-5H                        Probe
                                                            White Yellow Red    Green
    · Proper range for testing:
                                                    Probe(-)

      - Use XK range for Sanwa Tester                White               3K-50K  
      - Use X100 range for Kowa Tester               Yellow                 5K-100K
    · If the dry battery in the tester is weak,       Red                        
      the readings will be incorrect. In this
      case, check the dry battery.                   Green        5K-50K   
    · The Kowa tester readings are 100
      times the actual values. Be careful
      during testing.
 Replace the regulator/rectifier if the readings
 are not within the specifications in the table.
