I just had my battery light come on in my 93 Disco TDI, AFTER I shut down the motor, and of course awoke to a dead battery (which is new). Jumped it and the battery light was only on when I killed the ignition, and would stay lit even with the keys out. Then, the last little drive I had, the battery light came on while driving. Going out to try to troubleshoot today, but thought I'd see if anyone had an idea what the battery indicator is supposed to be indicating? With it coming on when turning the car off, I suspect a short somewhere.

Thanks in advance!

 

Light signifies battery is not charging which means either the alternator is not charging it or the battery has an internal short. Try charging the battery externally and then check it, should be over 12+VDC. With motor running and alternator charging the battery voltage should read 14+VDC.
