Here goes. An 85 300SD I recently inherited from my Dad. It has sat for awhile and I am getting reacquainted with this excellent car. As I go through and bring all the services up to date I am gonna have more than a few questions and have been doing searches in the archives of other sites as well.
Here goes my latest ???.
1. My Dad had a new set of Bosch glow plugs in a bag in the trunk along with a
notched metallic strip in a small parts bag.
2. The bag says Fuse strip and has a few different part numbers on it
178 3186 N17 125 3
3. The plugs are Bosch 80006
4. Currently the dash light for the plugs does not light and I do not hear a click
as in from the timer. The car starts immediately though ( I wait 30-40 seconds after the dash lights up anyway though).
5. There is a spot under the hood on the drivers side inner fenderwell that looks like something was mounted there at some point but is no longer there.

So what is this Fuse strip, where does it go, does this car have a timer for the plugs and where is it what does it look like ?
The ARS light in the dash came on while driving this to my home and as I thought all the belts were very loose so I am replacing them. The battery is 2 weeks old. I am hoping that with the belts done the ARS will go out and the dash glow plug light will come on. Any thoughts while I putter with this are appreciated.
