w123: charging light on dash dimly lit when key OFF
I wrote a longer thread on what happened with my '85 300d tonight, that hasn't got any traction yet.
Right now I think I have some of the issues under control. Right now my urgent question isL I am wondering why I would have the charging light dimly lit up when the key is OFF. Update: Found an answer, likely internal failure in alternator. Actually better than I was expecting, I was concerned I had had a wiring meltdown. Tried to delete the thread, couldn't. Weird.

There is a short in the circuit; I'd say a diode went out in your alternator.

I am inclined to think it's the alternator. When I tried to charge the battery with the cables connected, the charger shut down and gave a fault code first that the battery had been discharged too far to take a recharge. When I tried resetting the charger a few times the fault code changed to "no battery detected." I put on a 2A trickle charger and it auto shut down as well after about 5 secs. When I took the cables off and connected the charger to the battery alone, the charger began to work fine. Though I am not convinced the battery is actually taking the charge.

If you want to delete my original and more detailed info-dump thread from 6:35 p.m., that would probably not hurt anyone.
