For Mercedes with serpentine belts and dinky 70-90A alternators, the 143A or 150A units are the hot ticket.

First of all, many thanks to you for sharing those pics and your wisdom on this subject
.
First question...Did the W124 cars come with V-belts or just serpentine belts?

Is it necessary to re-clock the big alternator for my 1989 300ce?

Use 4ga at a minimum, preferably 2ga, and 1/0 (pronounced 'one-ought', or zero gauge) is about the biggest you can realistically use. Custom battery terminals are required, etc.

Do you know how long the cables must be?

I have the part numbers for the special 2-prong VR connector required, if anyone wants to experiment... they're only a few bucks. The auction closed ridiculously cheap! Too bad I missed that.  |
The alternator you have in the link titled "150A_b.jpg" is part number 010-154-83-02. That is supposed to be the same as Bosch AL0785X in my chart. Is this the one you used on one of your cars?
Which ones are "The very late model 150A alternators..." ? What I'm asking is which alternators from the ones I have listed will fit my 1989 300ce?
I called the dealer and checked the prices on the alternators...just for fun. Prices are in Canadina dollars and before applicable taxes. Here is what I was quoted:
ALO766X = MB 010 154 29 02 $1267.00 Canadian for new and is $568.00 for reconditioned.
ALO766X = MB 010 154 68 02 $1283.00 Canadian for new and is $N/A for reconditioned.
ALO768X = MB 011 154 32 02 Part number changes up to NLA for new and is $557.00 for reconditioned.
ALO785X = MB 010 154 83 02 $1235.00 Canadian for new and $557.00 for reconditioned.
