Guest Lee81 Posted March 7, 2013 Share Posted March 7, 2013 Easy to sort this connect a multimeter between the +terminal and the +connecting cord. Set to amps. You need to have the lead off the post of the battery terminal This will show the current drain from the battery with the ignition off. Should be no more than 0.12amps or so which is what a standard alarm draws. Assuming this figure is higher. Go to the fusebox and remove and replace each fuse in turn. When the current drain drops you can now see which circuit the drain is coming from. Certain ones such as heated rear screen and cigarette lighter you can just leave out until you find the problem. probably a short or faulty switch etc. Other you can't but you will now know what area of the car to check for the cause Quote Link to comment Share on other sites More sharing options...
