No all the links are almost 4 years old. Too bad, it had some interesting well thought out detail on wiring discussions.

Sorry about that, everyone. I changed domains and re-arranged the site a little a few years ago, which broke all of the links in my old posts. I updated everything in this thread, all the links should work now. The power blocks & distribution are different on all three of the cars I've done this on (87 blue, 87 white, 94 silver) so you can look at all of them for different ideas. I've got another 150A alternator that I'm going to put on my 'new' 1993 300D later this year (gotta finish other projects first.)

I have a 150A alternator from a 2003 (?) G55 AMG for sale if anyone wants it. It uses a different regulator than the other units I've been using - it has 2 small blade connectors instead of one small post. I'm not sure if it will work in our older cars or not - I was going to experiment but just haven't had time. If anyone wants it to play with, I'm willing to sell it pretty cheap. I have a new OE connector to plug in to the small blade terminals. This alt came from a very low-miles vehicle (under 5k, IIRC). A photo is at this link. Note that it could be modified to have TWO output terminals, which is mostly why I was interested in this type... would make installation in some setups easier.

Thanks for updating the links. Looks like you have seen every part of a W124 there is to see. Very nice quality wiring and wire routing. Jim

what sort of alternator upgrades are available for the 617 engines?

You can get a 100-120A unit from a VW or Saab, with V-belt pulleys, for the OM61x and M117 engines. There's separate threads about that mod... use the search feature and you should be able to locate more details. A number of people have done this to 617's. It's more work but it's possible.

I just did another upgrade, this time I installed a 150A alternator into my 1993 300D (this was LONG overdue... wish I had done it sooner). For this installation, I kept the stock battery cables, battery terminals, and factory power distribution block all intact. I hadn't done this before - my previous installs used aftermarket items instead.

This method makes for an easier install (and cheaper, too). I used two 4-guage cables to simplify connection at the stock distribution block. It works perfectly. If you don't need to attach large cables to feed aftermarket stereo amplifiers, etc... I'd recommend duplicating this setup. I took extensive photos this time, and documented the creation of the custom cable. A few sample photos are shown below... the full batch of pictures are available at this URL:
