New altranator not charging

I have installed two new alternators in my '85 e-28. Thinking the first one was a dud. I put the second one in, still not charging. I've checked all fuses, ground connections, the battery is new. What am I missing here? Is there a bad relay switch causing this problem?
Thanks in advance for any help with this issue.

Could be caused by a burned out bulb that illuminates the red battery light in your dash cluster. Start there. Is the light coming on when you turn the key to accessory?

The electrical connections to the alternator and battery would be the first things I would check. Sometimes wires and connections corrode under the insulation, where it's not visible. Corrosion and electrical problems are common with these older cars and very often difficult to detect.

^^^ +1... Check really carefully. Even to the point of removing and remaking connections.
