a few days ago i was changing the little latch that opens the hood. ever since then my battery light has been on. i replaced the alternator and my battery is good, even tested it, starter is good. basically everything is good just the light is on i accedennaly rubbed one of the wires from underneath the car where the fuses are into a metal plate and it made a litle spark and my light has been on since. any one have any ideas what the problem could be and how i can fix it?

Well, I would start with the wire that you clearly fried.

then check for common probs if its still on vacuum lines etc. i had this prob a while back and the charge system test said everything was good, turned out to be a disconnected vacuum line. if its running fine and everything and none of this is the prob reset the light and if it comes on again go to a shop.

How in the world does a battery light indicate a vacuum line problem? Most of the time, the OBDII system won't even indicate a vacuum problem, unless it's with the control solenoid.

Vaccuum lines have been known to throw a few different CEL code, like lean banks and things like that. I haven't seen the battery light come on for it, though.

Nothing is impossible in a Ford, though.

ya my battery light was coming on at stoplights and my car was almost stalling a while back. and the only thing wrong was a vaccuum line came off. i put it back on and the stalling and light went away. Weird i know.

Ah, the vaccuum leak was killing the idle.

No idle means no revs to keep the alternator charging.

No charge means the battery light kicks on.

Another mystery solved.
