How to find the cause of parasitic battery drain?
Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle. Then, remove the fuses one at a time while watching for changes in the multimeter’s reading.
Is the tracking device on my car draining the battery?
Spoke with the dealer regarding a battery issue and he said that the tracking device installed on the car is an issue. Apparently it’s powered off the battery with a passive draw of 0.25 (amps?). Thanks in advance! Yep, happened on our A3 as well.
How does an amperage battery drain test work?
The Amperage Battery Drain Test. With the amperage test, you probe the different electrical circuits searching for the presence of electrical current when there should be none. For example, if you detect electric current in the accessory light bulb circuit, you’ll know this isn’t right since all lights should be off.
How can I find out if my battery is draining?
Replace the fuse and disconnect each lamp, heater, or electrical device one at a time. Flip all of the switches that correspond to the components as well. Watch for the reading on the multimeter to drop to find out which component is causing the drain. For instance, say the offending fuse controls the power antenna as well as the radio.

When to look for a parasitic battery drain?
A parasitic drain is when an electrical device is using battery power when the car is closed, and the ignition key removed. Therefore, when doing this test make sure that the dome light, under hood light, trunk light, etc. are off.
Where is the red lead on a negative battery?
Place the red lead through the metal circle at the end of the negative battery cable. Touch the black lead to the negative battery terminal. You can use plastic clamps to secure the leads in place so your hands are free and the meter continues to operate.
