  REGULATOR/RECTIFIER
  REMOVAL
  Remove the front cover(page 14-4).
  Remove the regulator/rectifier lock nut and
  disconnect the regulator/rectifier wire
  coupler.
  Measure the resistances between the
  regulator/rectifier wire terminals. Replace the
  regulator/rectifier if the readings are not
  within the specifications in the table below.

                                                            Regulator/Rectifier
 Due to the semiconductor in circuit, it is                 Red                                   Black
     necessary to use a specified tester for                             Powder color
     accurate testing. Use of an improper
     tester or measurements in an improper
     range may give false readings.
     Use a Sanwa Electric Tester or Kowa
     Electric Tester for testing.
