This question is about an old motorcycle I own but I figure it requires general vehicle knowledge. I have the bike running good but there is an electrical short somewhere that I can’t find. If I leave the battery connected it will drain to 2 volts in an hour or so. Alternator works, battery is good, it even starts up if I try right after riding it, but if I leave it for more then 20 min the battery loses the power to start the bike. I figure somewhere a wire is draining juice to the frame. Any one know of tricks to find where the problem is? I just thought of pulling each fuse individually then checking to see if the battery still drains, that should tell me where the drain is right? Also is there any way I can tell that I fixed the problem without hooking up the battery and seeing if it is draining? I am getting sick of recharging the battery every time I think I fixed the problem. I have a multimeter.

Thanks

Sorry I didn´t read your post that good.If it only drains when the battery is connected pull the fuses one by one would be my way to go too.And hook up the multimeter at the same time.

Sure fire approach is to get an ammeter (or multimeter that reads at least 10A). Connect it in series with your battery and start disconnecting stuff.
