Yes it is important to isolate any component like the starter as the cause of the actual problem before going to all the trouble of removing.

You can scrub the outside surfaces all you want, but it will make no difference. To get good contact, you need shiny metal contacting shiny metal -- the outsides of the posts on the battery and the insides of the clamps on the cables. There's an inexpensive, special tool that makes cleaning these fast and easy.

Coke? That's a new one on me. Have you actually had it work?

yeah it eats away build up

Yeah it really works, I had an old cj5 and it looked like a bird had a case of the runs on it. Poured coke on it, waited a bit and it came right off. A little scrub with a wire brush and good as new.

Okay so when you say right do you mean if i was facing the car? Driver side or passenger side? How do i jump em, screwdriver? Is this the started solenoid? ON my old 77 chevy 4x4 i could crawl under and start it with a screw driver with ease? Im about to get out of class so lets see if it starts.

i noticed i was moved to the diesel discussion, i kinda figured that when it comes to the electrical system it doesnt matter if its gas or diesel. Just kinda curious

Im actually having the same problem with my car currently. I posted last week about it but it seems this thread is getting more attention so i figured id jump in here too.
Did you have one start that was slow and sluggish, almost like the battery was dying as it cranked? Thats when i noticed my problem first. Then the story is the same as yours. No clicks, no sounds. no start. Ive replaced my battery, and both cables. Headlights just barely dim when attempting to start. Ive also checked the ground strap. Is there only one on a 300d?

I have seen this happen many times and it was just dirty battery terminals.
+1. I've run around in circles before testing things and replacing starters only to find that it was my battery cable. They corrode at the ends, so you can get a replacement clamp for a few dollars, cut the old one off far enough to get to nice, clean cable and clamp the new one on. Probably something that should be done anyways after 20 years or so of corrosion.

Left/right always determined as sitting in the driver's seat. Don't think a screwdriver will touch both screws. A short piece of wire will work. I keep a piece off a section of Romex in my glovebox just for that purpose.

tried it and just got clicks

Well i ws trying to jump my car this morning, and used another jumper cable to connect at the junction box, got a few clicks but nothing.

When you replace the started cable is there a factory replacement or just go to the auto store and get one the right length?

Sure, there is a factory replacement part. Probably expensive, though.

U can use a parts store replacement but make sure the gage is at least as heavy as the original part. Maybe U could find a replacement in a Junk Yard.

I had this same thing happen to a car I just bought... sometimes it would start.. other times DEAD! NOTHING!

the way i found the problem was a voltmeter testing the static current draw at the negative battery cable when the car was off. (make sure the doors are closed too - dome lights draw power!) I pulled one fuse at a time till the amps dropped to zero on the voltmeter. then read the labels of that fuse, and checked those items.

I know there are billions of things on these german cars that can draw power... but just for fun.. give it a shot!

JUST in case its the same thing - the problem on mine was the power antenna... its broken, and in the halfway up position.. the motor was aparently trying to run even when the car was off. I just peeled back the panel in the truck, and unplugged the power connector from the antenna... now my battery stays nice and charged!
