03 f 150 clutch prob

Truck has been fine, 76000 miles on it. The other morning, very cold I might add, The clutch went to the floor and didn't come back. It wouldn't go into gear. Got it back to the house added a little fluid, clutch came back a bit saw a little fluid from bell housing. Slave cylinder?? Is it inside bell housing. Also When rpm's go above 3200 battery light blinks.??

Slave cylinder is most likely the cause, might as well change the clutch while you're in there. The other problem might take some diagnosis. Make sure your battery cables aren't all junked up and the belt is in good shape. Otherwise your alternator is probably on it's way out.
