Need help with using a Multimeter to test for battery drain

[doublem_1]

I have aquired a multimeter off of a neighbour so that I can check the amperage of the suspected draw on the battery. I understand I should take the negative terminal off and check between them but really don't know what I am doing, what setting to use etc. Plus, what would be a normal reading because I suspect there would be a small draw on modern cars. Has anyone any experience of doing this? And if so care to share the valuable knowledge

Hi there mate to measure the ampere being used you need to put your meter in line with the pos , if you using a auto range meter its will give use the reading straight away. if your using a meter with manual range start with mili amp. it shouldnt been any higher with the car off.

hope this helps

also make sure you use the hightst Amp range to start with (some have two), the last thing you wat to do is blow the internal fuse in a borrowed meter lol. once you know the current range you are looking at then drop to the lower setting if it is within range,
