A: Typical GM alt. When the brushes get worn down, the light can come on 
after the battery is fully charged or a loose diode trio will mess with it 
too. The regulators are pretty chicken feed on those too.

I have an 81 Eagle SX4.
Yesterday on my way home the alternator idiot light came
on. I pulled the Positive cable with the engine running
and the alternator is still charging.
I notice that when the engine idles really slow to the point of stalling the
light goes out. When I turn the key to start the Car the ALT is out. after
the engine starts the ALT light comes on.

Any Idea  on what would cause the aLT light to reverse itself.
Thanks
