TM 10-3930-664-24 10.  Carefully mate rotor and drive end shield (6) to ring end shield (7). 11.  To obtain proper running alignment, insert three 0.008 inch feeler gages between stator and rotor. Install four screws (8) and tighten in a criss-cross pattern. 12.  Install  transistor  regulator  (1) onto alternator (2) using screws (3).  Install suppression capacitor (4) using screw (5). 13.  Plug connector on capacitor (4) onto B+ terminal. G. TESTING 1. Install alternator in test set-up as shown in figure. Set regulated voltage on test set-up to 26 volts. CAUTION Connection between alternator and battery  must  not  be  disconnected  when alternator   is   running.      Semiconductors and regulator may be destroyed. 2. Operate  alternator  at  2000  rpm  for  2 minutes to bring alternator to normal operating temperature. 3. Reduce alternator speed to 1750 rpm. 4. Adjust loading resistor until a reading of 10 amps is achieved.  Indicated voltage shall be 26 volts. 5. Raise alternator speed to 2750 rpm. 6. Adjust loading resistor until a reading of 30 amps is achieved.  Indicated voltage shall be 26 volts. 7. Raise alternator speed to 6000 rpm. 3-94
