The other morning, I went out to start my 5.0 Mustang and the battery was completely dead. So, I went out and bought a new battery. The next morning, THAT battery was dead as well. I've borrowed a charger from my neighbor and charged them both back up, but something keeps draining them after installation into the car. I've thoroughly searched corral.net for advice on this, but have come up empty-handed. My multimeter shows no current draw between the negative terminal and body ground (with a fully-charged battery), and I've also performed continuity checks for shorts between the same two points...removing every single damn fuse and STILL showing continuity. All this has been done on advice from corral.net, and I'm still getting a serious battery drain. Any ideas?
