'83 240d possible alternator issue PLEASE HELP
So I just bought an '83 240d last week and to my dismay let me sit. It would not crank so I figured the issue was a dead battery. Jumped it, drove it to AutoZone and sure enough the battery was bad and they replaced it. They checked the alternator, all good.
The car drove great for the entire day after I got the battery replaced, but the alternator was obviously not working because the next day it did the same thing, wouldn't crank unless I charged the battery. After I charged it and drove for a little while, the headlights started to dim, the radio shut off, turn blinkers stopped working, etc. Seems like an obvious alternator right? The previous owner said he replaced the alternator not long ago and was sure it wasn't the alternator. And AutoZone said it was still in good shape. I checked all the belts, and they are tight.
What could possibly be not allowing the alternator to charge my battery while I drive?
Thanks for the input.
