    should  not light;  if it  does  light, 
    fit a new  solenoid 
    complete. 
    21.  Leave  the test  lamp  connected  and, using  the same 
    12 V battery  supply,  energize  the solenoid  by 
    connecting 
    a 12 V supply  between  the small 
    solenoid operating  Lucar terminal  blade and a 
    good earth  point on the solenoid  body.

    27. Check  the armature  insulation  using suitable  test 
    equipment.  Connect the tester  between  any one 
    commutator  segment and the shaft. 
    The method 
    illustrated  uses a 
    110 V, 15 W test  lamp.  If the 
    lamp  illuminates  the armature  is faulty,  and a 
    replacement  component is required. 
    Reassembly

    drive  assembly  with Mobil 
    22 grease.  Smear the 
    drive shaft sun and  planet  gears with Rocol

    one direction  only, independent  of the  clutch  body. 
    Replace  the unit  if unsatisfactory  or 
    if teeth are 
    damaged 
    or worn.
