Re: [MBZ] 240D Glow Plugs not Glowing Update

[Curt Raymond via Mercedes]

I've only had to replace one once, the time the feed line to the relay on my 
(formerly Dwight's) '78 240D somehow laid on the exhaust pipe where the 
insulation melted causing a short. That car absolutely would not start without 
glowplugs. 
My '83 240D would complain but would eventually start...

Don’t touch it.  They degrade from heating and cooling over time, and become

Re: [MBZ] 240D Glow Plugs not Glowing Update

[WILTON via Mercedes]

'Bout 15 years ago, I needed one of those fuses; went to local VW 
stealership and got 2.  Installed one and put the spare in an envelope in 
glove compartment of the 81 300D for possible use later.  2 or 3 years 
later, I was  cleaning out the glove compartment when selling the car; 
opened the envelope and found that  the fuse had disintegrated into very 
little melted "beads."

Lesson:  Don't store the spare where it gets hot.

Yup.  Or just a "worn" fuse.  I have never overloaded one of those
fuses - but I've replace a lot of failed ones.

I'll repeat what I've written before about the best method I've
found for testing glow plugs.

I attached 12 AWG wire leads to an old automotive dash style
ammeter that reads -30 0 +30 Amps.

To use it, I pop the top off of the glow relay and unplug the
connector for the glow plugs. There is a contact for each glow plug
in this connector.  I clip one meter lead to the fused side of the
big, screw-in fuse and then touch each glowplug contact, one at a
time. The socket has pin numbers molded into it, and these numbers
correspond to the cylinder number.

This method tests the supply 12V, the wire, and the plug. When
cold, a good plug draws about 20A (Well, on my meter it point
to the mark for 20 amps. I have not calibrated or tested the
accuracy of that meter...) It will drop back to about 15A
after 8-10 seconds.

Once the one wire is connected to the fuse, DO NOT LET THE
OTHER WIRE TOUCH CHASSIS GROUND!!!  Or the big fuse will blow
and possibly so will your ammeter. :)

If the plug is bad, the current will usually be less.  If it is
shorted it will be much more.

If the wire or connectors are in poor shape, the current will
be less.

If the supply voltage is low, the current will be less.

As always, a good resoldering with perhaps a replacement capacitor or two

149279

Since the fuse blew, you could still have a grounded GP.  If so, the 
next fuse will blow also.  Each fuse will blow until you locate and 
correct the problem.  It is also possible that one of the wires to the 
GP is shorted to the block.  This is a common problem in the OM60x 
engines, and less common on the iron head engines like yours.  I'd 
guess you have a shorted out GP.  The test procedure is in my post 
from last night.  Without a meter that has a range of 0-20 or 0-50 
ohms or a finer scale, or a digital that can read in 10th of an ohm, 
it is very difficult to discriminate between a shorted GP and a good GP.


At any rate, before you stick in another fuse, test the ohm readings 
at GP wire harness that plugs into the GP relay.  Read the ohms 
between each of the 4 sockets with liners in them and a good ground.  
A good GP will read 1.4 ohms + or - 0.5 ohm.  A grounded plug will 
read 0 or the same reading you get when you hold the two meter probes 
together.  (depending on the meter, this may not be 0)

Re: [MBZ] 240D Glow Plugs not Glowing Update

[Curley McLain via Mercedes]

The 80 amp fuse is intended for running 6 glow plugs.  It is the WRONG 
fuse.  The correct fuse looks the same but will be 50 amp.  This was in 
my post yesterday.  Another post yesterday told you the fuse was in the 
top of the relay, under the relay cover, and exactly how to take the 
cover off.


Since the fuse blew, you could still have a grounded GP.  If so, the 
next fuse will blow also.  Each fuse will blow until you locate and 
correct the problem.  It is also possible that one of the wires to the 
GP is shorted to the block.  This is a common problem in the OM60x 
engines, and less common on the iron head engines like yours.  I'd guess 
you have a shorted out GP.  The test procedure is in my post from last 
night.  Without a meter that has a range of 0-20 or 0-50 ohms or a finer 
scale, or a digital that can read in 10th of an ohm, it is very 
difficult to discriminate between a shorted GP and a good GP.


At any rate, before you stick in another fuse, test the ohm readings at 
GP wire harness that plugs into the GP relay.  Read the ohms between 
each of the 4 sockets with liners in them and a good ground.  A good GP 
will read 1.4 ohms + or - 0.5 ohm.  A grounded plug will read 0 or the 
same reading you get when you hold the two meter probes together.  
(depending on the meter, this may not be 0)

Hello Everyone,
I went out to the car and searched for the fuse and finally found it 
inside the cover on top of the relay. I hope it is the right fuse 
because it was blown and came out in two pieces. It is just a steel 
band and looks like the fuses in the on-line websites. The only 
lettering I can find looks to say 80A and is followed by a P with a 
circle around it. Is this possible?
This car is a very late 83 240D, one of the last ones sent. Over the 
years I have had to use the VIN number in order to get the right part. 
I think MBZ was using the parts they had left when they made this car. 
Some parts were clearly from earlier years, others may have been last 
minute changes.

I think I’ll look for a fuse first (80A?), It might fix it.
Thank you all again for your help!
John Ingram

Re: [MBZ] 240D Glow Plugs not Glowing

[Curt Raymond via Mercedes]

The '78 came to me with about 18 gauge wires from the relay to the glow plugs. 
Strangely whomever had originally made the wires ran them in series even though 
they were parallel plugs. It took a lng time to heat the plugs.
I made new 10ga wires, ran them in parallel and starting improved immensely.

80A.  That's what I meant. I think.  Whatever it is you can get them at 
the stealer, they are (or used to be) pretty cheap.  Keep a few in the 
glove box along with a screwdriver for any field repairs.

Re: [MBZ] 240D Glow Plugs not Glowing

[Curley McLain via Mercedes]

No, but I'd guess you can buy a new relay for the price kent wants to 
bodge up your car.  About $130 for a new one and $30 to 75 for a used 
one.   Check out ebay  You can use a 4 cyl or 5 cyl relay.  Just put in 
the right fuse.


If you think you want to go the pushbutton relay route, let me know.  I 
can help you find the right relay and fuse.  You can make your own 
wires.  It won't save you much money, but it will be cheaper than Kent's 
kit.

Thank you all for the great replies to my questions. I knew I would 
get the benefit of all your experience. I will start testing. Since 
the dashboard indicator light goes on this indicates the fuse is good. 
Looks like I need to get the relay.


There also is the push button relay kit from Mercedes Source, replaces

GP fuse -- if it is like my 300TD it is on the firewall in a little covered 
holder, it
is a 20A strip fuse about 2in long and screws onto the contacts.  They cost like
a dollar, buy a couple to keep in the car.

Glow plug relay could be bad too (I'm guessing this car has a relay) but the
fuse is the likely culprit.

Re: [MBZ] 240D Glow Plugs not Glowing

[Curley McLain via Mercedes]

I made one correction to Philip's post below.  What he said, plus a 
couple of clarifications.   Batter voltage should be battery voltage.


1.  240D GP fuse is NOT 20A.  It is 50 Amp.  You can find them at VW 
stealers if FLAPS does not have one for you.  5 cyl  engines use a 
bigger one, 60 or 65 amp I think.   OM603 and 606 6 cyl use a 80 Amp 
fuse.  Be sure you get the right one.


2.  The GP relay can and does fail in at least 2 ways.  a: no light ever 
as someone said.  b: Light on as expected, but does not go out.


 To test:  Check voltage at battery, post to post, then each post of 
the GP fuse (to ground) in the relay.   If alles ist gut to that point, 
(~12V) then pull the big plug on the relay, and test within 10 sec of 
turning the key on, voltage between each of the posts to ground


At this point you will know if you have a bad relay.  if voltage is at 
each end of the fuse, and you have tested the fuse, but there is no 
volts going to the GPs, then the relay is bad (or your testing procedure 
is faulty)  I like to take the fuse out to test it.  If it is bad but 
looks good, it will fall apart when you take it out.  (Best to pull the 
battery ground when you do this, as there is always voltage to the GP 
fuse terminals, as was previously pointed out.


While you have the plug off, turn to the lowest ohm scale you have and 
test between each socket in the plug with a liner and ground.  Each of 
the 4 positions should be 0.7 ohm.  .5 to 1.5 is acceptable.
Most meters won/t give you much definition at that low of a reading.  
$10 meters will show zero or near zero.  This is still good data.  if 
you have a cheap meter and it shows 0 ohms, you either have a good plug 
or a short to ground plug.  If you get infinity or anything higher than 
1.7 ohm, you have a failing or open circuit plug.


3.  DONT EVER buy a champion glow plug, unless you plan to change it 
within 1hour to 1 year.  They don't last.  Buy Bosch or Beru.  The Bosch 
10 digit number ends with 039.  It will be 0 250 xxx 039.  Sorry, I 
forgot the numbers represented by the xxx.

The glow plug relay assembly located on the forward side of the port
(driver side in the USA) front inner fender. It is about 1.5 inch
wide and 4 inches long, tilted so the forward end is quite a bit
lower that the aft end. Lift the forward (slightly narrower) end
of the cover to lift the whole cover off.

There are two squarish connectors. The bigger forward one is for
the glow plugs. One wire leading out to each plug. This can be
handy for testing the plugs.

The smaller one, in the middle, is the control.

At the aft end is a metal strip held down by screws. This is the
glow plug fuse. It is always on, so be careful. The outboard
screw is the supply side. This fuse can fail but still look okay,
so to check it be sure to touch and wiggle it.

But if the glow lamp on the dash lights up, the big screw-down fuse
is okay - and the control wires are okay. On mine, if the
connector for the glow plugs is disconnected, the dash lamp glows -
but obviously the plugs don't heat up.

Do you have a volt meter? It can be useful for any electrical
testing. A test light can also work to see if there is power at
the big fuse. Like I said, I think it's okay because the dash lamp
turns on.

I would start by seeing if there is power going to the glow plugs.
I would unplug the big connecter at the relay and measure the
voltage between each pin and chassis ground. There should be
battery voltage on each of them when the key is first turned on.

If not, make sure there is power at the inboard fuse screw, and the
outboard screw.

I have never had a relay fail, so I would make sure the rest of the
system is working before condemning the relay. The relays do
fail. Oh, you can listen for the "click" of the relay engaging.
Not a foolproof test - but it's data.

Hello Everyone,

When I turn the key on my ’83 240D the glow plug light goes on as 
usual but it does not go off after 10 seconds or so as it used to. 
When I turn over the engine it doesn’t even try to start. It seems 
that the glow plugs never turned on. Is there a relay or fuse that is 
the normal cause for this? If so, what is it and where is it?


Thank You,
John Ingram

I was thinking I have seen ones that are different amperage ratings - the strip 
is wider or narrower depending on the size.  They’re the same length, however.

That would be for the series glow plugs.  In '83 the relay would be
between the port headlight and the fender.

Not if the dash lamp turns on.
