Battery light stays on after keys out of ignition
 

Hey all, I have a 99 SL1 that I just pulled the engine out of, to replace the clutch. A week after putting everything back together, when I shut the car off, and even with the keys out of the ignition, I notice the battery light stays on in the instrument column. Any ideas? The next morning the battery is still charged, and the car starts just fine. I hate electrical issues...

Also, I had issues with hard starting when it was warm, but a new fuel filter, (expensive), and it starts like a pro!
