I have something draining my battery. Yesterday I got a new Optima battery and today it's dead. I searched past posts and found where they said to put a test light between the negative cable and the post and then start pulling fuses till the light goes out. I unhooked my radio, unhooked the clock, made sure the dome light was out, and then I pulled all the fuses out one by one and the light was still on! What does this mean? I'm pretty "electronically challanged" so any input is appreciated.
