ABS light/brake light goes on and off, lights flash on and off, battery drains, will recharge with alternator but drains again, headlights flicker or dim then come back (while driving), same with A/C fans. Can fully charge battery with charger at night - check the next morning it is low or dead. Battery is less than a year old, alternator replace a year ago at the same time.

You have an alternator problem, have Kragen auto or a store like it test the alternator for proper operation, it's free.

It could mean the alternator has gone bad already... with the car off, the battery leads should read 11-12V.. with the car on, the battery should read 13-14V.. if it's lower then it's not charging your battery and if it's higher, it's damaging your battery....
Testimonial: "thanks so much for your advice...will have this checked into :)"

My 2002 Ford
Escape had a similar issue later in 2006. My alternator died and I needed replacement. After replacing, the light would come on and off at times. When everything running (i.e. radio, air conditioner, driving lights) and tocuh electric windows up the power would lower and sometimes battery light on dashboard would come up. Original mechanic could find out what was going on and I lived for 2-3 years with it.
This past August 2009 after a long trip (i.e. 8 hours or so) my battery died. Brought to a auto parts place and they determined it was the baterry and the alternator. Since I was back on my home town I went to a good friend that is a mechanic and he fixed it for real.
He had a similar issue with three different Escapes coming back with alternator or baterry or both death. He found out that Ford has an official report for Escapes that when this happens the electric fan behind the radiator are short circuiting, affect direclty the baterry and alternator killing them, and needs replacement.
Try this and may work for you.
