E36 Alternator indentification

Is there a way of telling what alternator my '92 e36 has in it without removing it? Maybe by VIN number, or ECU?

Look on the side of the alternator or grab a mirror and look in the back of the alternator. Are you getting all the dash lights to light up while you drive or the battery being drained every evening after a drive?

The battery is draining. About every two days of work-and-back, I have to throw it on a charger if I want to use it the next day after.

Is the model on a sticker on the back, or will it be stamped metal?

Do you have the Harman Kardon sound system on it? If not, get the 80 amp alternator. You can get the 140 amp as well, but it's your money.

Mine now rocks an Alpine. I don't have any amps or anything, so an 80AMP would work, but from what I'm told, the amperage is not the only difference between the different models.
When I called the parts store, they said that there were 6 different ones.
There were amp differences, but also, there is a threaded pivot foot on some, but not the others.
He, of course, was just looking in his database, so for all I know, they are all threaded.
Do you know if there is a threading difference between them?

There is a mounting difference on some of them so you want one that matches your mount. if you get one from a pick a part lot, take the mounting hardware too.

PS: You can do alternator indentification with a large hammer. Hit it and it will put a dent in it....
