I have a 1994 f150 and over night the battery drains and I can't start it in the morning. I can charge it and start it. It will run fine but when it sits over night or a long time the battery drains enough that it wont start. I've replaced the altenator and battery about 5-6 months ago so I dont think that is the problem but im unsure.

You have a short circuit somewhere in the electrical system that's draining the battery.
