Serpentine belts only.

No idea. Every car is different. Maybe, maybe not. You'll find out when you test-mount it. Not a big deal.

Yes, that's the one I have in my 300D with an OM603.

For a photo of one of the "very late" alternators, click here. That one is from a G55 AMG. Notice the two-pin, flat-blade VR connector instead of a single threaded post for the 'D' terminal - that's the difference.

Anything except the 'very late model' ones will definitely fit.

Don't forget you need a core to get the 'reconditioned' price - you have no core to return. In the USA, some are available for $300-$400 rebuilt, even without returning a core. Much preferred, IMO, to just buy a used one for $100-$125.

Last question

..... looking at Post #1 and Post #15, will all of these 150 amp alternators fit? Are these one that I listed considered the old style?

Thank you very much for answering all those questions

lino · #19 06-01-2005, 04:29 PM

I just bought a 150 amp alternator and I should get it on Friday or Monday. Is there a good brand or better brand of cable and connections? Where should I buy these from?

gsxr · #20 06-01-2005, 09:19 PM

I'm not too picky on wire brand, as long as it's not junk. Be careful to route the wire away from anything it could rub on and wear through the insulation.

As for terminals, you'll want to figure out what size cables need to be attached at the battery, and buy a terminal that will accept all the sizes you need for YOUR setup. The stock wire to the starter will fit into a 4ga or 2ga hole. I needed a terminal with holes for one 0ga (to alternator), one 4ga (to starter), another 4ga to my headlight relay fuse block, and one 8ga (to the block that feeds the rest of the car). You may need something different. I got mine here:

I think this is the one I used on my blue car:

Thank you for all the help

. My car didn't even start today after putting in the new volatge regulator yesterday. I want to go shopping for the wires and connectors tomorrow so that I can have everything ready for when the alternator arrives.

lino · #22 06-02-2005, 03:14 PM

The zero guage wire here is $5 a foot and available in a brand called Suntec (not sure of the spelling). The only had 2 feet of the Rockford left so that was no good. They also have some JL Audio 2 guage at $7 a foot. They recommended the Suntec stuff.

How thick should the other wire be? The one that connects to the D+ ?

gsxr · #23 06-04-2005, 02:39 PM

The D+ wire is small - I used 16ga wire.

You're the best thank you! The shop I went to didn't have a zero guage battery terminal connector. I really like you copper ones. Are they copper?

lino · #25 06-08-2005, 05:39 PM

The alternator came in early this morning. Here is the tag:

The new alternator is 150 amp. It's pretty heavy!

Here are the threaded posts for the B+ and D+. I don't know what the middle one is though

Side profile. I haven't changed the pulley yet.

I wanted to sandblast the cover plates and glass bead them, but I'm already into this project for way too much money and too much time has gone by. I already had the alterator tested and it tested very well.

Here are the new wires I had made this morning. Thanks to gsxr (Dave), I was able to get this far with this project

.

Here is what I bought:

2 battery terminals that can take a zero guage wire.

1 zero-guage wire for the alternator to the battery approximately 4.5 feet long

lino · #26 06-08-2005, 05:39 PM

1 zero-guage wire going from the negative battery terminal to the shock tower.

1 zero-guage wire going from the engine block to the car body.

This is the only brand I was able to find availabale on the spot where I live:

Tomorrow morning I'm going to install it.

lino · #27 06-09-2005, 10:28 AM

So I got the alternator installed today. I forgot to buy some parts though. I forgot to buy the 2 washers needed to secure the wires on the alternator. Anyway, I got them and eveything was ok.

Here is the alternator installed.

Here is the wire running from the B+ threaded post on the alternator going to the battery positive terminal. That wire is a little over 4 feet long. I had it made a little longer to be on the safe side.

I wasn't able to use the gold plated terminal I bought for the positive battery terminal, because the terminal I had bought wasn't able to take the other oem wire which was quite thick. I needed one like the one gsxr used. It is very hard to find that stuff on the shelf where I live.

Here is the one gsxr used which is the right one:

Here is the wire going from the negative battery terminal to the shock tower.

There is still the ground wire that I didn't do yet. I thought about running the wire from the engine block to the car body like in the picture below, but maybe I'll wait and see the oem ground wire first before I decide.

I used the oem wire for the D threaded post on the alternator. You can see it in the first picture.

lino · #28 06-09-2005, 01:29 PM

I just changed the position of the short wire so that it's not touching the other one. Here is the before:

Just as a pulley removal note...

If it's going to be a core alternator, you can shove a screwdriver in the fan blades to lock it and use a socket.

It works, but I haven't do it that way in years with compressed air handy.
Massive wiring...

Thanks for the suggestion Steve! I'll put an 80A in mine when the 70A one goes south. I guess with the fan, A/c and headlights running at idle- we'd be well over 30A. Besides its cheaper, which makes it a better option=)

Walter's MB in Riverside quoted me $129 for the wiring harness from the alternator to the battery. Rodents have chewed the covering off. It looks like 3 wires inside.

I have purchased 9' of 1/2" wire covering (Cool Tube Extreme from Buschur Racing) and I hope to cover my wires to prevent this in the future. For some reason they love my MB and leave my Dodge Dakota alone.
