Battery dead, AGAIN. ABS light on + other elec issues

Battery has died 3 times now spaced out over the past month. But I jump it and it's fine. :confused:

Just this past week, the ABS light was randomly on in the morning at start up, but it usually went out when the car was warmed up. Yesterday it didn't go out, the ABS light stayed on all day. And this morning my battery was dead for the third time. Related somehow?

A few weeks ago my security light was on for a day, then went away. Also heard rpm clicking through the radio which has also vanished.

Something is randomly draining my battery? The car normally turns right over, no hesitation at all. Except for how it's been dead 3 times now. Help! You all know what you're doing more than I do...
 


The ABS light is probably due to either a bad wheel hub assembly, or bad wiring to the speed sensor on the hub. Jack the car up, put your hands on the tire at 12 and 6 and try to push/pull it up and down. If it moves, then you have a bad hub. If not, then time to break out the multimeter and check the harnesses to the hubs. Start with the front 2 as they seem to be the most problematic.

The clicking through the radio, battery drain and the fact that it jumps easily seems like it is an alternator issue, like it's not charging enough and is slowly allowing the battery to drain. I'd have it tested and see what you get. Also, check ALL of the battery cable connections and be sure they are clean and tight. At the battery, the alt, and the ground on the trans.
 
x2 on checking connections,

buddy of mine had a couple of "no crank" mornings and a intermittent bat light, he went out and bought a new alternator only to find the battery posts rotted right off
