How did I find out my battery was draining?
How did I find out my battery was draining?
The drain was found by going to each fuse dock and testing the energy draw readings with a meter to see if any system was drawing power when it should not be doing so as the car was off. The amp, an issue MB has had problems with a lot, was drawing power when the radio/car were off and slowly over the course of a few days was draining my battery.
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.
Why does my Mercedes Benz battery drain so fast?
The amps could be the only thing drawing that much power to drain the battery. Check each fuse and it’s housing, if you have the electrical equipment to do so. I had to take my car to a friend that worked at Mercedes-Benz and he checked each fuse slot for any extra energy draw than is supposed to be there.
What causes battery drain on Dodge Ram truck?
Click to expand… You don’t do an Amp draw across terminals, you use a CT around the positive cable. He is talking about voltage drop as without the truck running and the power being used the battery’s voltage is going down resulting in a dead battery. RoadRamblerNJ likes this.
What does it mean when your car battery is draining?
Dan Ferrell writes about do-it-yourself car maintenance and repair. He has certifications in automation and control technology. A car battery drain can leave you stranded anywhere. A parasitic battery drain is when an abnormal and continuous discharge of power occurs after having shut off the engine.

How can I find out if my battery drain is faulty?
To locate the faulty circuit, start pulling out fuses, one at a time, from each of your vehicle’s fuse boxes. Begin with the under-hood fuse box, if there’s one. Pull one of the fuses and watch your meter’s reading.
How to get rid of negative battery drain?
Remove the negative battery cable from the negative battery terminal. Find the negative cable, which will be marked with a minus sign (-) and may have a black cover over it. Remove the cover, if applicable, and use a wrench to unbolt the negative cable from the terminal.
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.
What does it mean when battery drain is slow?
A slow battery drain when everything is off is called a parasitic power loss. This happens when something – a glovebox light, an amplifier, any electrical component – is pulling power from the battery when it shouldn’t.
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.

Is there a way to drain a battery in one day?
That seems like a tiny amount, but a single incandescent dome light pulls enough power to drain a battery in one day. Remember that the drain doesn’t have to take your battery to zero overnight, just low enough for it to not start.
How to drain residual electricity from new device with non removable battery?
