– Alternator Test 

 

 

An alternator is the device used to produce the electricity the car needs to run 
and  to  keep  the  battery  charged.  The  alternator  uses  the  principle  of 
electromagnetic induction to produce voltage and current. The four main parts 
of the  alternator are the Rotor, Stator, Diode Pack, Voltage Regulator and an 
Ammeter  or  Indicator  Light  to  inform  the  driver  of  any  problems.  All  of  these 
parts must be in good working order for the alternator to do its job. 

 

 

 
The Rotor is a coil of wire wound around an iron core. The Rotor rotates as the 
alternator  shaft  rotates  and  current  passes  through  brushes.  The  Rotor 
winding passes the Field current. This causes the Rotor to produce a magnetic 
field. So basically the Rotor is a rotating electro magnet. 

 

The  Stator  is  a  set  of  three  windings  fixed  to  the  case  of  the  alternator  and 

these  windings  are  static  i.e.  they  don‟t  rotate.  As  the  Rotor  rotates  its 

magnetic field “cuts” each Stator winding in turn, this induces a current in each 
winding. The outputs from the Stator windings are 120 degrees apart and are 
alternating current (AC). 
 
But vehicles run on DC current, so we need something that will convert the AC 
current to DC current. This is the job of the diode pack. A diode is an electrical 
one-way check valve that will let current flow in only one direction. The typical 
diode pack uses four diodes to accomplish this. AC current is feed in on one 
side  of  the  diode  pack  and  DC  current  comes  out  the  other  side.  The  diode 
pack  here  will  rectify  the  alternating  3  phases  from  the  Stators  and  combine 
them  into  a  single  Direct  Current  which  also  works  the  dash  ammeter  or 
indicator light. 

 

Now  that  we  have  a  DC  current  that  the  vehicle  can  use,  we  need  a  way  to 
control  that  current.  That  is  the  job  of  the  voltage  regulator.  As  the  name 
implies,  it  regulates  the  voltage  going  to  the  battery.  It  does  this  by  turning 
current to the field (stator) terminal of the alternator on and off.
