I'd try a new or used relay. A bad relay can run down the battery.
Used relays can be pretty cheap.

Jaime,
As per my previous note, the glow plug lite in the dash lites up OK
when the key is turned to the ON/Start position but, when the
condition occurs when it doesn't start, there's only a slight click
and a signal from the starter as if the battery was almost dead . .
. not enough power to turn the starter enough to start the car.
Note, a new glow plug fuse was installed in March. What I don't
understand is that the car wouldn't start yesterday, but started OK
today prior to my doing anything to it.
Thanx.
Glenn

Hi Glenn,
This is why information from the internet isn't always so reliable ;-)
Funny... I have the same issue with my 79 300SD. I take apart the
relay once a year to clean it up with deoxit and some paper towels.
One of these days I'll break down and buy a new one, but until
then...
One thing you should be weary of is the fuse. It might look good,
but not be able to support the 50+amps when the plugs are glowing.
I've seen them when they look ok, then break in two when you remove
them a fiddle with them a bit.
What exactly is the problem when it doesn't work? No light and no
glow? Or no light with glow? If I remember correctly it is a
failure mode for the light to not come on, but still provide power
to the plugs if there is one or more thats failed.
Good luck,Jaime

Jaime,
Prior to going out to the garage to see what else I could do about
this, I found the following from a guy on the PeachParts site:
Yes, you can pull it apart and clean the board/resolder the components.
If it's stuck on just pull the "bucket" off, removing a screw in each of
the four corners. Check the solenoid (the thing that moves) and it's
contacts. Sometimes water will seep in and corrode on the contacts. They
should be smooth. If they're not use a piece of sandpaper or a really
fine file to remove any built up corrosion.
If that doesn't work, just get another one. Unless you want to spend
the time testing and resoldering each component.
Today's episode:
1. The car started OK prior to doing anything.
2. The glow plug lite in the dash lites up OK when the key is turned
to the ON/Start position.
3. There's continuity between the two sides of the glow plug fuse.
4. There's power to each side of the glow plug fuse when the key is
turned to the ON/Start position.
5. For grins, I DeOxit'd the female pin plugs to the glow plug relay box.
6. The car started OK after messin' around as well.
If the bloody thing misbehaves on my attempt to go to church
tomorrow, I'm not sure what else I can do.

I think the problem is that you sanded the contacts. Its like
ignition points, if you sand off the surface coating then the
likelyhood that they corrode and fail again are much higher.

I had a buzzing problem upon starting attempt with the GPR in my '84
300D back in March, took it apart resoldered the PCB, lightly sanded
the contact points, and cleaned the external pin connections and
it's been OK till the other day when all I would get was a click
when attempting to start and it sounded like the battery was dead.
I checked the battery voltage and it's fine, so I took the GPR apart
again, cleaned things up, lightly sanded the contact points, and
DeOxit'd the contact points and external pins and the car started
fine for one day, but it was back to the click and sounding like the
battery is dead. I remembered someone indicating back in March that
moisture can get into the GPR box, but I sealed the edges w/ RTV the
other day. I'll dig into it again tomorrow to see if I can find
what the problem is.
Any suggestions? TIA.
