I've got problems to obtain an alternator for the SD (1984).
The catalog shows the same alternator for all W126, 81-85:
http://catalog.peachparts.com/ShopByVehicle.epc?q=&yearid=1984%40%401984&makeid=63%40%40MERCEDES+BENZ%40%40X&modelid=6208%3AED|10000134%3AMBC|1510%40%40300SD&keyword=alternator&subcatid=P:240866@@Alternator&mode=PA
However, the '84 doesn't have the three spade plastic connector. It has a two single lugs, one heavy gauge for power, and one light gauge.
Anybody else find a similar problem?
I wanted to pickup the NAPA alternator with the
lifetime warranty, but they have the exact same problem. They show the triple spade connector.
