    Electrical madness

    Strange one that I can't seem to figure out just yet. I've noticed the last two times I've driven my car that the ABS, Brake Lining & Brake lights would flicker on the dash (bumps seemed to provoke it). I assumed ABS sensor & planned to put it up on the lift this weekend. On the way home last night the ABS light stayed on and my headunit flickered as well. I got back home & went out to start it this morning & now have a no-start situation anne the headunit will not fire up. I have seemingly full battery power (OBC settings still in tact). I think I can hear a relay click when I hit 'start' but nothing seems to get to the starter itself. I checked all the grounds under the hood as well as both battery terminals and everything is clean & tight. It seems strange that these 3 might be related, but without a test light or meter at home I can't diagnose too well. Could it be a relay? If so, which one?

      I finally figured it out: bad battery. It showed no sign of getting weak or anything. It dropped a couple of cells internally during a turn. Still had enough juice to power half of the electronics in the car and produce some very wacky results during testing.
