  One thing to remember on those other systems (at least on the 
earlier ones) is that they run 6V glow plugs with a cycling controller 
to heat them up quickly without burning out.  Controller goes kaput 
and so do all the glow plugs.  Glow time is determined by V rather 
than temp so have a loose alt belt, bad battery, connections or 
weak alt. and up goes your glow time so more wear on the glow 
plugs.  12V plugs don't usually see those type of systems, which 
will shorten life if there's any seemingly unrelated problems.
