ummm, well, every time you turn the key to the instument, or start position, then the battery light should come on. But it should go off as soon as the vehicle is started.

How long does the battery light stay on after the truck is running?

My guess would be a bad connection somewhere. The dash light isn't receiving the signal that the vehicle is running.

No other issues though? 99 f250, in the wrong part of the forum, but no biggie. Question, since you have a 99, you have an OBD II port. Has your truck thrown any codes? (much easier for you to check than OBS trucks)

Interesting. Well, the light coming on, then going off, would indicate a loose connection somewhere. (like a wire moving around). Not sure where to look though.

Bryan, I think I saw you post in another thread where some other people were having a similar issue. I believe that they were having issues with some of the wires connecting to the alternator.

Have you checked these wires out?

In all my experience with electronics and wireing. A sparatic signal, is usually caused by a loose/ inconsistant connection, or a part that's about ready to go toes up. (and I don't think there are too many "components" between the batteries and your dash indicator, and if any of them were going out, you would probably have other issues as well).
