I did the delivery valve seals on my '84 190D and IIRC the injection pump
seemed louder after doing the job than before. Also as I remember (and it's
been probably 10+ years) that noise declined over time.

There is no ecm that controls anything with the glow plugs. If the relay gets
power, but no power is coming out of the pins to the glow plug harness, then
the relay is bad.

So I’m thinking that maybe the ground to the relay is the problem or that there
is an ecm issue. The relay gets power but doesn’t put out power to the glow
plugs. But where is the relay grounded? The three connections are the power lug
to the battery, the harness to the glow plugs and the harnes
Yes my car has three connections as you describe. Big plug to glow plug, cable
to battery and small plug. Small plug corresponds to 5 pins on relay. One
connection on the plug is live only when ignition is turned on so I presume
that is the ignition on.

On my W116, if I know the engine is warm enough (e.g. after fueling or other
short stop) I won't wait for a full glow cycle. Ususally the glow light goes
out when I start the car, but occasionall
Ahh so the “activator” might not be working even if power is going through the
system. That would be the main thing to check then

Used to be there were THREE connections to the relay:
A big plug that went to the glow plugs, a big cable that
went to the battery, and a small plug that was command
and control. The first two are Duh!, but they all need to
be working correctly, or you don't get a good start.
IIRC there was an ig
Get a wire and connect one end to the power coming into the relay then stick
the other end on each pin in succession and see if you get power/heat to that
particular plug. If the plugs get power you’ll know the problem is with the
relay. If the plugs don’t heat up then there is some other issue.
How do I jumper around the relay? Battery positive terminal to what? The
harness has 5 pins.

I don’t hear the relay click but I don’t think it’s a mechanical relay. Having
no glow and then replacing the relay with factory new one and still no glow
makes me doubt that the new relay is bad though.

Ok so in addition to the wire that goes to the relay power lug, there is a
second harness going to the relay which is comprised of 5 wires going into a

I’m not sure how to check for that. There is constant power at the lug on the
relay. With the ignition in the on position there is no power at any of the 5
pins on the relay that go to their respective glow plugs.
I inspected the chaffed harness and while there are some exposed wires where

I had the opportunity to get a Fluke (probably several) from a previous
employer when a building was closed down.
Sadly I didn't realize that I wanted/needed one and passed...

They're awful.

The electrical safety classes I attended at Los Alamos National

The signal from the keyswitch should be there at the relay. If it's not,
of course it won't work. Used to be the purple wire, IIRC.
