TM 10-3930-653-14&P (3)   Tighten  pulley  nut  to  350  to  400  kg-cm  (301  to  344 in-lb).     When     pulley     is     tightened,     make     sure     that deflection of V-groove is within specified value. V-groove deflection: Less than 0.3 mm (0.012 in) Fig. 4-194.  Tightening Pulley Nut 4-7-5-6.  TEST Before conducting an alternator test, make sure that the battery is fully charged. To  conduct  a  test,  it  is  necessary  to  use  a  30-volt voltmeter and suitable test probes. Set  up  a  test  circuit  as  shown  In  Fig.  7-46  and  test alternator in the manner indicated in the flow chart below: Fig. 4-194.  Testing Alternator Note: a. Do  not  urn  engine  at  more  that  1,100  rpm  while test is being conducted on alternator. b. Do not race engine. Fig. 4-195.  Testing Alternator 4-109
