TM 10-3930-671-24 STATOR REMOVAL- 1. Grasping  the  stator,  apply  pressure  to  separate stator from housing (Figure No.  37). FIGURE NO.  37. All  connections  of  the  TA  stator  are  either  welded  or crimped and should not be taken apart.  Do not attempt to solder replacement leads to the ends of the windings. The test procedure  for  each  type  stator  is  different,  due to the fourth test point on the Wye stator.  The objective is   the   same.      The   tests   must   indicate   that:      (1)   all windings  are  a  complete  circuit.    (2)  They  are  not  short circuited   to   each   other.      (3)   The   windings   are   not grounded.    Discoloration  of  the  enamel  on  the  windings is   evidence   of   overheating   and   may   cause   a   shorted condition.  Test stator leads as indicated in Figure No’s. 38 & 39. FIGURE NO.  38. FIGURE NO.  39. STATOR    SERVICE    OPERATIONS    -    The    alternator stator  consists  of  three  individual  windings  wound  on  a common core or lamination.  The lamination is Insulated tor durability (Figure No.  40). FIGURE NO.  40. The  usual  reference  to  alternator  stators  concerns  the method  of  terminating  the  ends  of  the  three  windings. They  may  be  connected  in  a   Wye,   or   a   Delta   circuit (Figure  No’s.    41  and  42).    The  Delta  circuit  used  in  30 and   45   ampere   TA   alternators,    does    not    have    the common termination, just three connecting leads for the rectifying diodes (D - E - F), (Figure No.  41).
