Description of 
Starting 
System 
Westerbeke diesel  engines use  electric starters assisted 
by 
glow plugs for both  normal  and cold  weather 
starting.  The fignre below shows a cross-sectional view of one cylinder.  The glow plug is located in the 
combustion chamber 
so 
that its tip is in the injector nozzle's spray path.  When the glow plug is energized 
by 
the PREHEAT button, the  plug glows red at the tip  and  assists  in igniting the  fuel.  The result is  a 
rapid start with less wear on the starter. 
This  system  is  common  to Westerbeke  Diesels.  The start circuitry is  designed 
so 
that the  PREHEAT 
button 
must  be depressed  for the time specified  in  the  "Preheat"  chart.  Then, while keeping  the 
PREHEAT button engaged, the 
START button 
is 
depressed to crank the engine.

NOTE:  The  START  switch  will  not energize  unless  the PREHEAT  button 
is 
depressed.  When 
depressing the preheat switch,  we are activating the glow plugs  in the  cylinder  head 
so 
use  the preheat 
intermittently to avoid overheating the glow plugs.
