Hi.
I have a faulty voltage regulator in my 1995 C280.  I ordered what I believed to be the correct part from Phil, and proceeded to install it.  What I now have is a car, dead in my driveway, with the alternator cover off (picture 1)
In removing the black alternator cover, one of the nuts made a "crack" sound.  I was being gentle, but, obviously not gentle enough.  The crack was an electrical lug breaking off.  (picture 2 and 3).
I don't see where this new voltage regulator goes, making me believe it's the wrong part - unless I just don't see it (picture 4 is the new regulator).
Can someone tell me what's going on here?  If I have the correct one, where does it go??
I can solder the broken lug back on using my heavy duty soldering gun unless there's some reason that's a no-no, but, I still have a bad regulator.  Do I have the wrong one, or the right one? 
I'd REALLY appreciate help with this one.  My car's dead at this point, and I have kids to drive to school tomorrow.  I'll certainly have to come up with a solution to that problem, but, the sooner I know what to do, the sooner I can order the right parts.
Thank you all, so much!!!
Kind regards,
Bill Griffith
