REFERENCE TM  9-2320-387-24-I INFORMATION STARTER   ClRCUlT 0 ^II . l I WARNING Disconnect     negative   battery cable   before   disconnecting and reconnecting     PCB   harness. WARNING There   is  battery   voltage   at the  PC6 at  all  times.     Failure   to  disconnect battery   cable   will  result   in damage to equipment or injury to personnel. Replace  harness  or repair  wiring (para.  4-80). n 0 ^II . . WARNING Disconnect     negative   battery cable   before   disconnecting and reconnecting PCB  harness. WARNING There   is  battery   voltage    at the  PCB at  all  times.     Failure   to  disconnect battery   cable   will  result   in damage   to equipment    or  injury   to  personnel. Replace  harness  or repair wiring  (Pam.  4-80). b REAR  OF  ROTARY   SWlTCl- WARNING Disconnect    negative   battery cable   before   disconnecting and reconnecting PC6   harness. WARNING There   is  battery   voltage   at the  PCB at  all  times.     Failure   to  disconnect battery   cable   will  result   in  damage   to equipment    or  injury   to  personnel. Replace   PCB   (refer to para.  4-4). VOLTAGE MULTlMETER 1.  Set the  voltmeter to a  DC  volts scale  of at least  40  volts. 2.  Connect  the RED  lead  to positive and the BLACK   lead to negative. 3.  Be  sure  to read the  correct  scale. CONTINUITY    (RESISTANCE) MULTIMETER 1. Set  the voltmeter  to an  ohms  scale  of about 1,000   ohms. 2.  Connect  the  RED  and  BLACK   leads  to the connections  stated  in the  question. 3.  Be  sure  to read  the correct  scale.    Less than  5 ohms  indicates  continuity.   For an open  circuit. the  meter  should peg  full scale  (needle  all the way  to the  left). DC  VOLTAGE   O-45 VOLTS STEIICE-R   TEST  89 I 1. Connect   RED  clip to the  indicated  test point, BUCK clip to negative  or ground. 2.  Start  Test  89,  DC  Volts. 3.  Displayed   reading  is in volts. RESISTANCE    AND   CONTINUITY 04,500    OHMS STE/lCE-R   TEST  91 I 1. Connect   RED  ctip and  BLACK   clip to the indicated  terminals  in the question.   RED  to the  first, BlACK    to the  second. 2.  Start Test  91,0-4,500 Ohms. 3.  Displayed   reading  is in ohms.    Less than  5 ohms  is continuity.   If the  resistance  is over 4,500   ohms,  STE/ICE-R     displays  .9.9.9.9. 2-287/(2-288   blank)
