![]() Most vehicles have a little leaking current. A leak current of less than 0.1A or 100mA is normal. The 15 minutes are meant to be sure any draining devices have been put off or on stand-by by now. If it's been 15 minutes since you disconnected the battery, note the current that the multimeter is displaying.A main fuse may power multiple sub fuses next to it. Try to find out what the main fuses are, they're usually bigger or different from the rest.Sometimes it's written in the driver's manual delivered with your car. Usually it's in the inside of the lid that covers the fusebox, or there's piece of carton or a sticker nearby explaining the fuses. Find the legend that contains the information about what each fuse powers.They're hidden behind a storage compartment lid, they can be hard to find so google for it. Under the floor at the feet end or under the seats. They can also be in the side of the boot/trunk, under the dashboardĪt either the passenger or driver's side and sometimes in a box Mostly the main boxes are under the bonnet/hood, or in the side of the dashboard where the door covers it when closed. ![]() Locate all the fuseboxes your car has.Your alarm may go off, try to disable it. Disconnect the positive terminal on the battery, and place a multimeter (in high current mode) between the battery pole and its terminal. It's rather easy to find a drain if you're a bit lucky, so here's what you can do to find the drain: I'd also suspect something draining on the battery, but alternatively the batter could be discharging internally. March I took a 9 hour road trip, when I got to Vegas, the voltage was still 12.4, when I got back it was the same, but the next morning it read 12.6, it started to drop 2 days later though The charging system and alternater are fine,while it is running the voltage stays between 13.7 and 14. I have put it on a trickle charger and a fast charger twice, all day long, the voltage won't go above 12.4 The battery is about a year old, it held a full charge for about 3 weeks, the voltage sits at about 12.3, that is fine to start the car, but every day I don't drive it, it drops 1 point, so during Thanksgiving it dies over the weekend, then every weekend after that, I jump startedit every Monday for about a month, until that didn't work, AAA came out and started it, I took it back to the mechanic who put in the battery, he said there was a drain somewhere, he kept it two days and said he couldn't find a drain anywhere, and the battery was fine, the voltage was 12.4, and holding steady, for about three weeks, now it is dropping every night again.
