I have intalled a new battery, and over the last 24hours the battery has lost voltage while in the car(from 12.3 to 11.90). I did remove every fuse from the panel and unpluged the alternator and put a test meter on the battery. I touched off on the positive post with one side, and with the positve cable detached place the other lead of the meter on the positive cable. I am still getting a tone (positive indicator of continuity)..which means to me I'm still sending current somewhere. I was under the understanding that I would not be showing continuity if all fuses were removed?? am I incorrect?
