Ok so I just placed a new battery in my 91 Fox Friday evening. Went out for a bit, came home. Didn't drive it on Sat, went to drive it yesterday (Sun) and the battery was dead. What's the best way to find what is draining the battery so fast?

Your alternator is prolly dead. Take it off and take it up to advance auto and they'll test it for free. Thats my best guess....

HACKGT350

disconnect the neg battery cable and take a multi meter and put it on amps. hook one lead to the battery and the other to the cable it will tell you if you have drain on the battery i forget what the spec is

My bad, I forgot to mention the Alternator is fine. It's new and I had it tested prior to posting this.

Please tell me how you have come to this conclusion!!

Seriously, if that's your best guess, keep it to yourself. Not trying to be a dick but posting misinformation is of no help at all.


bbbngowc, you obviously have a draw on the system, and a pretty big one to kill a brand new battery over a 2 day period. It should be pretty easy to find.

sunvisor lights staying on while the flap is closed.

or bad ground cable.

wigle the ground wire and listen for sparking, or better, cut the insulation and watch all the white power float in the air

MAN are PRO and I the only ones who know how to attack this situation???...and hackgt350...remove the neg battery cable as Hack stated and hook a multimeter in series set to amps and look for the draw spec is 25 to 50 milliamps max...over that and there is an excessive draw....pull fuses until the draw is removed and after you find the circuit the draw is on get a diagram and unplug components on that circuit until the draw is gone...(fuse must be put back in place while testing components on circuit with draw)..anyway check for obvious things like glove box light trunk light on sunvisor lights ect ect.....
