Marshall,

    this document specifies '81-'84; was there something different about '85s, 
or
does this document pre-date '85s?


cheers!

Situation:
Son's '85 300D glow plug light does not come on.
Outside temp is below 40F and car will not start.

The 80A fuse in the GP control box is OK.
I suspect it needs new glow plugs.  But please help confirm my diagnosis is
probably correct.

Two questions:

If my memory serves me correctly -
If the GP light does not come on, the following are the potential causes by
priority:
1. Blown fuse.
2. At least one bad glow plug
3. GP control system is faulty
4. GP light is burned out.

Is this correct?

I expect this car probably has the newer parallel glow plug configuration,
so I'm not sure how the controller behaves.
Other question - if the glow plug light does not come on, does that mean the
glow plug circuit is not activating?
In other words, will one or more bad glow plugs prevent the entire glow plug
cycle from happening?
This attachment is appropriate for ALL of the 617.95 engines.

The pages I sent were published in '84. They're actually good for all of the diesels thru 1987 EXCEPT the mid model year '87 190D 2.5 turbos (that had a different controller without any fuse).
