Car Battery Drains Overnight Or After Days Of No Use! PARASITIC DRAIN
ฝัง
- เผยแพร่เมื่อ 22 ม.ค. 2020
- Car battery drains overnight(dies), or after days of no use, parasitic drain, parasitic draw, engine will not start. How to easily find/locate/identify the source of parasitic battery drain on your late model car, vehicle, SUV, truck, or boat without losing computer or sound system settings/programming. Enjoy!
ATTENTION: The testing methods shown in this video can be performed using either battery terminal(sometimes one end of a car battery can be much harder to get to, or one cable has very limited movement), but it's much safer to use the NEG battery terminal since it's connected to the vehicle's chassis/engine ground.

How much time is normal for a battery to drain in a parked vehicle
Hello there I bought a Ford Sort Trac and bought a brand new battery but it is still draining. I took it to AZ (you know the Zone) and they tested the battery and Altintor both were in good order. I saw the you said Security system could drain the battery too, where would I find that wiring/fuse (it dose have a Thift light indicator on the dashboard) .? Please get back with me at your earliest convenience thank you 🙏
hello, do you do a product review? We have a product, I can send u a sample

I worked at a car dealership for 15 years (as an aftermarket electronics installer). It always amazed me how many technicians didn't have the slightest clue of how to diagnose a voltage draw.
Before some tech gets heated over this comment, the percentage of ignorance, is about the same among aftermarket electronics installers.
I'm not meaning to be insulting. The point being, never stop learning, I've learned things from people that were just beginning, and I've taught things to 30-year vets. Our ego only serves to limit what we allow ourselves to take in.
Happy wrenching.
Good comment
Personally I get into a wierd mental state which is "I understand enough - why is what I am doing still going wrong" the irritation kicks in and I lose the ability to think clearly.
@@simonmasters3295 I always try and just walk away when that frustration sets in, go talk with another tech about what they're working on for a few minutes or do something completely unrelated. Look at the problem fresh again.
So true. At the nationally famous HamVention I was told by a guy selling all sorts of electronics from a huge booth that if you increase the voltage of an LED then it'll therefore draw more amperage. I said, no it will actually draw less amperage, I've tested dozens of them. We couldn't agree.
At another booth they were selling humongous TV antennas for the home. I asked how many more tv channels these would pick up. He said the same number as before. So I asked, "What's the point in buying this expensive monstrosity?". He was now trapped in a corner and couldn't answer.
FYI, when you install a huge antenna 50 feet high, you'll get to stations from all over the tri-state area! (Unless, of course, there is no "tri-state area", such as Alaska, Hawaii or the middle of Texas.)
Well said..Ego n stubborn attitudes kill learn continuity.😅
Thanks your awesome wish I could pick your brain
I use a infrared thermometer to check for the hotest fuse in fuse box to locate the short I the circuit..sometimes you can trace the heat on the wires to the voltage drain
While the vehicle is off correct?
Darn we think alike makes sense we are looking for a hotter fuse then any of the others
Great video that'll help a lot of people! Thank you for the video and always a thumbs up!
I hope it does. Thank you very much for watching!
HEY I KNOW YOU Great to see
Ladies and Gentlemen it's Project Farm!
Hey,PF,whatcha doin here??
Project Farms is such a great guy, just the fact he checks out lots of others channels and give his support
That is a topnotch complete summary and delivery of testing for a parasitic draw.
Thanks
This video is the best video I’ve ever watched on TH-cam. Perfectly explains each step. Now I feel my life’s nemesis, my wife’s piece of crap 2013 Ford Escape, will lose again.
Done this during my career working on cars. Very well explained for anyone too fully understand. Imho
Imho, you should have used TO
There you go! You did this vid much better than the older vid!
Thanks for sharing. That post clamp probe clamp jumper wire is a clever technique, too!
This works because at 10amp setting which uses a shunt allowing for current flow...Thanks for this simple comprehensive video
Only two decades later.... I FINALLY found someone who can not only explain it, but 'explain', what and why this is important... KUDOS!

thanks so much! easy to follow and it makes sense! Found my issue immediately, after wasting time at the "dealership" shop and with a private garage. Looked to TH-cam and found your video, and voila problem solved.
WITH SO MANY USELSEE VIDEOS OUT THERE THESE DAYS,,,,,,,,,,IT'S GREAT TO RUN ACROSS ONE THAT REALLY HELPS . THANKS.
If you don't own a multimeter, or if like mine it only measures current in the microAmp range, try this. Disconnect your positive lead from the battery. Connect a battery charger that has an Ammeter fitted (most decent ones do). Note the charging current. Reconnect the positive cable to the battery and reconnect the battery charger, note the charging current.. My car had such a large parasitic drain that the two current readings differed by 2 Amperes. 2 Amperes was the parasitic drain.
My wife’s V W battery would go dead overnight. Battery was still under warranty so I replaced it. It went dead overnight. To make a long story short, I called the service department and explained to a lady mechanic over the phone what was happening. She asked me if the car had a Clock built-in. I said yes..She said that’s the problem. I think her and hung up. I didn’t believe it until I unplugged the clock and my test made her stop showing a current loss. It was the factory quartz clock that was killing the battery overnight
I have the same problem I drive a Mercedes-Benz E320 every morning I get up it's like my car will not start or it may start no lights won't come on the doors won't unlock the radio won't come on then the next morning I wake up and try to start it up it won't do anything and I do have a built-in clock
We have a 2013 Passat that we can’t figure out why this keeps happening. Every couple of days it’s dead
@@konstantintrehagyrevopoulo972
Yea, after you test battery and charging system and those test good, and also this is for when battery dies overnight obviously, you run these tests to find out what the actual problem is. Which clearly was not the battery or charging system
How did you unplug the clock
@mtthw741 2011 Jetta TDI. Same issue. I don't have a built-in clock, though. Already replaced the alternator. Not sure if I need to waste money on a starter or not. Definitely wasting money on new batteries.
Very detailed and very well demonstrated. Thank you for the content.
Thank you for this video and detailed explanation that even someone like me, 0 experience, could understand!
You're welcome. Glad it was helpful!

Excellent, clear and concise, my 2019 Ram 1500 has a parasitic drain and I am certain that this video tutorial will help me figure it out! Love that eastern accent too!!
Great explanation very good thanks!
Great video. Probably be better approach to do this test on the negative post versus the positive post.
I love your precision...
Thank you Doug. I use an OBD-ll battery back up port ,has they are supposed to keep the backup memory in the ECM. With all the new crap that are on timers to put them to sleep, it can be a headache to do the tests needed at times. Even opening the door can wake up some circuits. Best way I found was to open the door and fix the switch to fool the car into thinking all the doors are closed and just wait till it goes back to sleep. Liked,Shared. All my best.
I prefer those. The power is directly to the computer, which is perfect when swapping out car batteries. Thanks for watching Bobby!
@@electronicsNmore m:
Learning is life long.
the fact that disconnecting the car battery to do can result in an expensive trip to the dealer speaks much about the sad state of affairs in the car industry ......
Really no reason for it, there should be a memory backup system using a capacitor. Thanks for watching!
Very useful video. Your explanations were very clear. Thank you
Thx for clear demo on post/ connector management.
Good tip, straight the meter pin above the post, and lift.
Outstanding video ! Thank you
Excellent video, great job, thank you for sharing!

Thank you sir. Used this method and found the drain on my battery- a trailer hitch adapter.
Glad it helped
that engine bay is sooo clean
great, what did you set the multi meter on?
Thanks a lot for your excellent video,
I had this issue since couple of months ago the car couldn't start strongly and when I checked the battery the voltage it was about 11v, my battery is not that old I bought it 2 years ago.
After I watched the video, I checked the battery current when the switch was off and the current was about 3 Amperes, I removed and put back some Relays/fuses and play with wires behind the both fuse boxes suddenly the current goes down to almost 0A then I drive the car for 1hr and the battery Voltage is about 12.5V now and the car is starting with no problem, I don't know what was really happened, hopefully the problem is solved.
Nice video buddy, I'd done forgot about this one.
Thank you!
Just bought a 04 impala SS and it had this problem. I did the multi meter test on it and out of all things, The battery run down relay was causing the parasitic draw. 900 MA draw with the relay in to 30 MA with the relay pulled.
Nice trick! Thanks.
Excellent video!! 👍🇨🇦
I already watched Scotty killer do this but I liked your video too
Thank you for this easy to understand and well explained video, I have a new battery and it's draining if don't drive it every day, won't start.
Did you find a solution?
@@Lobsterman5481 I've been lazy, just disconnect my battery at the weekend 😂😂
@@mickchaganis6607 LOL tell me about it.
I have the same problem. I barely use my car since covid and working from home.
Great tip... Handy combo wires 👍
Just taught this to a friend who has been dealing with a drain on their car for a year. Had to disconnect the battery every night. Finally talked with me about it and they wanted to know where I was over a year ago.
Many people don't know these things, some are lucky to have friends that know, or they can visit YT. :-)
I know you made this comment 1 year ago but do you remember what car it was causing the problems?
@@captinhoop I know it was a early 2000s Suburban. Don't recall if he ever figured out where the drain was from.
@@captinhoop It can happen to any car the causes can be alarms, stereo circuits, alternator, really anything in newer vehicles it might take longer to find the root cause.
Good video the only thing I would add is if you don't want to jump in and out of the vehicle to look at the meter what I do is use my booster cables. I connect one clamp to the post on the battery and the other clamp to the ground clamp of the vehicle. This allows me to run the booster cables inside the vehicle then I can clip the leads of my meter between the two booster cables and have it in a spot where I can read it easily without getting in and out of the vehicle or moving too much it's really handy when working on a vehicle like my F-150 that has the fuse box in the passenger side footwell. Again great video with lots of good information thanks for the tips on how to not lose settings
Great idea. Thanks for sharing it, and God bless you!
NICE VIDEO.
Heres my problem: I was working on something and was putting the battery cables back on. While putting the negative on my ratchet is a long handle flex head. While wrenching I was looking around and the handle hit the positive post. The battery never acted properly since. Had it tested and I killed 2 cells but it worked for awhile.
This was very clear and very useful thank you

How do you guys do this inside the passenger glove box fuses? I am 6'3" and 190bs, I can barely sit in that sport, let alone get my hands in that space and hold the leads close enough together to get an accurate reading!
good.
Fantastic! Great video.
Glad you enjoyed it!
My car alarm has been going off at random times for the past month. Looked up what it could be, got battery replaced because that was not holding a charge and it was 8 years old anyway. Problem is still there with brand new battery,
I purchased OBDEleven and scanned the modules, and it came up with fault code 01134 (H2) alarm, implausible signal. Google search suggests possible fault with fuses/wiring/alarm unit. Got a breakdown assitant to have a look and he suggested there is parasitic drain somewhere and that i take it to a car electrician who would need the car for a few hours to go through every electrical fuse etc. He also told me that these VCDS and ODBEleven devices dont really pinpoint the issues, they only point your in the right direction so that you can investigate and diagnose further.
So after watching this video my hunch is that some electrical component is causing parasitic drain. I fully charged my brand new battery (it read 12.7v) and 4 days later the alarm went off. Checked the battery voltage and it was at 11.6v suggesting that something was draining the battery when my car was not in use.
Great video Thank you
Glad you enjoyed it Cary!
Very helpful! It seems so obvious, once someone shows you how to do it. :D
Yes! Google and content like this on YT can restore the sanity of beginners and experienced practionners alike!
Nice Video !!
My Belva amp is drawing A LITTLE power when key is off, THE REMOTE WIRE From Pioneer Stereo IS CONNECTED RIGHT. When the key is off, the little green light on the amp and the remote bass control knob both shut down. I got 3 cars with amp/sub kits I installed, I seen one site that said that drain is common with some low budget crap. It's not sucking major juice, just a little when it should not be using any power at all when it's shut down.
what is the make and model number of the DC clamp meter you are using in the video?
If you have a Ford Hybrid the problem may be the main hybrid battery (not your 12 V battery) If that big battery is defective it will drain the 12V one that starts the engine. This happened with Ford Cmax Hybrids. My wifes new CMax 12V would run down overnight. Many trips to the dealer for months. It got so bad that she was afraid to change any settings. They finally fixed it. Gave no reason what the fix was. I later read that a defective main big battery was the cause.
Thanks 👍 gonna give this a try in the morning I'm pretty sure my problem is one of my security door buttons because when I Lock my doors with auto button the alarm goes off 02 pathfinder. But I can lock it with the key at the truck by turning it twice no alarm but back glass is open
Great - do be VERY careful you know that there isn't a large current draw. Using thin leads or shorting them can cause them to get very hot, melt or even vaporise! In the same manner that a fuse works. This aside unusual current draw such as failed alternator diodes etc. is a real pain!
Try running g a ground wire from the Alternator to the ground on the battery.Fixed my problem on 2005 Mustang
Doing the lord’s work with this video! 😂

Learning about parasitic draining.
I've got an alarm system. Believe it's completely dead. I was wondering if there was a separate fuse for that alarm system, or is the fuse part of the radio system. I want to completely remove that alarm system. It was nice at first, but I constantly had a drained battery as the alarm system was always on. Any advice about this? I'm removing the batteries from the remote control.
How do you perform the terminal test with GM side posts?
So what do you do if it IS the ECU? How can you confirm? I have pulled every single fuse and relay, including the screwed in maxi fuses and main fuse for my car audio on my 1991 Honda Prelude.
Excellent demonstration
Thank you!
So I’m assuming you can’t just look at each fuse to see if it’s burned out and then replace the fuse? Or this different I’m confused lol
Great video. I have a question. Does modern cars' come with a 'disabling switch's at fuse box' to disconnect draining current i.e. door light, etc??
No.
Amazing video!! Thanks for your help.

thanks for your informative video. what are the other 2 methods to check parasitic draw?
What is ECM and how can you tell which fuse is for the stereo?
Pure gold
Hi . Thanks for uploading handy diy videos . Do u think the procedure would be same for bmw x5 too? Or is it different
You're welcome, glad you enjoyed it. The method should work fine. Thanks for watching!
Did you find out why your X5 was draining? I’m have this problem with my Range Rover
great info ....thx

When the key is off, the little green light on the amp and the remote bass control knob both shut down. I got 3 cars with amp/sub kits I installed, I seen one site that said that drain is common with some low budget crap. It's not draining major power, . just a little when it should not be using any power at all when it's shut down. when I first put tester on it starts at 0.05 then drops to 0.01 after like 3-4 seconds. It does that every time I do the test.
I found the fuse drawing current, it is the one that feeds the Low Current Board which is inside the SJB, guess what, that board is attached to a lot of other components and it gets harder when there is little information regarding that circuitry lol, sometimes you don't get it easy as a fused light or component.
Once you identify the circuit, you do have some work to do.
Excellent video - dead on the money.
Your dope!🔥
Glad you liked the video!
Some newer vehicles may run Evap pump during off hours. This will draw some current from the battery but it's totally normal.
Also, the clamp-on current meters are not very accurate at the low end. I wouldn't trust it for measuring very low current. It's best to verify it's readings with a meter connected in series with the battery.
Hello Andrew. The particular clamp meter I used was designed for leaking current testing, so it does work well on the low end. Not every method is 100% reliable, but the one shown in this very is extremely useful. Thanks for watching!
@@electronicsNmore I think he was just pointing out that you need to know the behaviour of the vehicle you are working on
@@peteahwanzo1504 Correct, he was referring to the LDP(Leak detection pump) that some newer vehicles have. I'm not aware of any that run with the car parked with the key out of the ignition.
@@electronicsNmore I'm not aware of any of the top of my head either, but that does not mean they do not exist.
@@electronicsNmore A 2017 Lexus GX460 does just that. Startled me the first time. You walk into the garage hours after the car has been parked and the panic sets in .
You need to trip the hood latch, and clamp any door sensor shut and leave door open if you need to get in car during test, you also need to let any arming system time out so car thinks it is set for the night
He explained these steps in video before this one.
have a 2008 ford escape dont need to trip the hood latch , just the doors.
@@balbutie ford focus has a hood switch
Is it normal for the new battery to last about a year if I drive 2 to 3 times a week for about 6/8 miles each time ? It used to last about 3 years when I have to drive everyday BUT for 4 miles a day. Is the battery being charged if I just let the engine runs without driving ? Also, does it prevent the battery from discharging ? Thanks.
Can you disable an alarm system on a car? I assume that if it had a fuse, then you would have already identified the alarm as the culprit?
What about non post style batteries? Mine only has one bolt going into the neg terminal
RADIATOR!!!
yep that one is of the hidden culprits too especially with aluminum radiators because of galvanic corrosion and electrolysis. quick fix is a radiator cap with zinc anode. DAMN lost my beer buzz had to concentrate. worth it though to add to this post

Self testing my Ford Fiesta 2015 ecoboost dropes to 10.4 when engine is off with lights ac everything on. Then when engine is on it goes to 143. Should I change the battery?
We had an e350 van pulling 3500 mA of current. It was the alternator. Mind you, the alternator would charge fine but it was drawing mega amps overnight through it.
Faulty diodes.
@@electronicsNmore is that right? I replaced it with a new $115 motorcraft one and all my problems went away thank god.
Fantastic Video and Explanation. BTW where can one buy the Alligator Test leads you are showing here. One end is large and one small? I cannot seem to find these anywhere. They are all both small on one end.
He custom made them
Thank you for the video. I couldnt do the drain test since the battery die right after I turn off the engine. Volt drop after shutdown within a few seconds to 10 V. since you mentioned the alternator cable, How I can change the alternator cable?
bad battery
Warning, do not do this on a DeLorean with a Mr Fusion unless you have spare fuses for your multimeter.
🤣
@@krystal5887 I knew I should have RTFM...
It will also skew the Flux capacitor.
My 8th gen Honda Civic's battery was drained, I managed to recharge it but after about a week it was drained again like about -2 V per day. I did a test with my multimeter, set it to 20A (it doesn't have a 10A setting) at it jumped from 0,48 to 0,20. Does it mean a parasitic drain on a 20A measure too?
I have same problem check battery,fiuse,alternator, amplifier help I don’t no what to do thanks
