ARMY TM 9-2815-255-24 AIR FORCE TO 38G1-95-2 MARINE CORPS TM 2815-24/4 FIGURE 3-13.  Battery Charging Alternator Test Circuit NOTE Carbon pile and ammeter must be capable of handling the alternator rated output. (3) Starting with the carbon pile off, slowly increase load while observing ammeter and maintaining 5000 rpm. Increase load until an output voltage of 27.0 to 29.0 VDC is achieved.  Record the output current at this point.  Acceptable current is 38 amperes at 70 to 80°F (21.1 to 26.70C). 3-11.7.  Installation. a. If removed, install jumper wire (18, FIGURE 3-5) and nuts (19). b. If  removed,  position  mounting  brackets  (15  and  17)  on  timing  gear  cover  mounting  holes;  secure  with  two capscrews (12), washers (13), spacers (16), and nuts (14). c. If  removed,  position  adjusting  strap  (11)  on  water  pump  mounting  hole;  secure  with  capscrew  (9)  and  new lockwasher (10). d. Position battery charging alternator (5) and bracket (4) between mounting brackets (15 and 17) and secure with capscrew (6), new lockwasher (7), and nut (8).  Do not tighten. e. Secure battery charging alternator (5) and bracket (4) to adjusting strap (11) with capscrew (1), new lockwasher (2), and washer (3).  Do not tighten. f. Install fan belts on battery charging alternator pulley, refer to end item maintenance manual. g. Connect electrical leads to alternator as tagged during removal. 3-12.  STARTER. WARNING Exercise  care  when  bench  testing  starter.    Ensure  metal  objects  do  not  contact  connection points  as  severe  arcing  will  occur.    Failure  to  observe  this  warning  could  result  in  personal injury. 3-12.1.  Bench Test. a.
