(g) Push down on the voltage regulator armature  until  the  voltage  regulator contact    point    barely    touches    the adjusting     screw.          Measure     the airgap between the coil core and the armature   of   the   voltage   regulator. Do  not  measure  between  the  core residual brass pin and the armature. The correct voltage regulator airgap is 0.084 inch. (h) Adjust  the  correct  regulator  airgap to  0.115  inch  in  the  same  manner as   for   the   voltage   regulator   unit described in g above. (2) Electrical  adjustments.    Install  set  of  test adapters as illustrated on figure 9. Note. Refer  to  C  figure  9  and  polarize  the generator. (a) Cutout  relay  closing  voltage.    With voltmeter connected as shown in D, figure  9  start  the  engine  and  slowly increase speed until the cutout relay contact     points     close.          Observe voltage reading at which this occurs.  It should be 25 to 27 volts. If    adjustment    is    necessary    turn cutout relay adjusting screw clockwise to increase or counterclockwise    to    decrease    the closing voltage.  Set closing voltage at 26 volts. 34
