Have you ever said, "my battery keeps dying but I know the battery and the alternator are good"? Well perhaps you have a parasitic draw. A parasitic draw is a short in the system which can drain your battery over time without you knowing why. In this video I'll show you how to find the problem and then we'll talk about how to fix it.
If you don't have one you will need a multimeter: amzn.to/2ru0BzF

fun story about how everything is related (especially on late 90s Chryslers). passenger side window regulator goes out on 02 Grand Cherokee while we're out of town. I artfully use a rubber mallet to hold the window up to get us home, and I just disconnect the main harness for the door so I don't accidentally force it and potentially do more damage. in addition to NONE of the power locks working, and the right rear window not responding, the dome lights stayed on. pulling the fuse for the dome lights causes the AZC climate control to not power on. given that only left windows worked, A/C did not turn on, and it was 80 degrees, I had to stop again and replace the dome light fuse. the next day I did what I should have done at first, and just disconnected the connector for the window motor.

Matt Hooker my 04 has done that multiple times. broken wire in the harness that goes to the driver's door will do that. Caused my AC to stop working, caused power locks to stop working, all 4 windows to stop working, all the lights on the dash to come on randomly, etc. Fixed the broken wire and everything worked fine afterwards.

i did something similar with a late model zj like the one in the video, i simply replaced my doorpanel. then the key fob didnt work, no worries i close up and go to bed. wake up at 5am to head to work, try to start the jeep and the alarm goes off. neighbors loved it. found out after a whole day of research and chasing wires,missed work btw, that the passenger door switch assembly(window switch and door lock switch) is where the sensor for the key fob is. also found out you cant disable the alarm in a 97 zj. and if you use the power locks to lock the jeep, the alarm arms and unlocking it with the key dosent disable it, only disarms using the fob or unlocking the rear hatch with the key for some reason. my jeep had the hatch lock cylinder replaced at some point before me and that key trick didnt work. has worked on my buddies 95 zj tho. yay chrysler. i sold the zj and have just have my mj now. and a honda lol.

I've had my car in the same repair garage for several years now, for the same fault, battery drain.. After having two new batteries installed within a short time, we paid for an electrical check by a car electrician, ovr £70 each time, the garage did other various checks. The electrician said no faults in the electrics, we were finding that the cooling fan was staying on after switching the battery off, this was intermittently. Then the garage fitted another new battery and a new alternator. Problem of battery drain continued. We'd charge the battery up and it would slowly drain, until the second or third week the battery would be drained. My car is 2002 vauxhall diesel 1.7. I'm so fed up. I've been giving the car a good run at least once a week, thinking I was topping up the battery but, this morning I went to start the car and the battery just made that dying sound, no start.

Dummy me kept thinking I would have to find the end of every wire one at a time and test them. No one has ever ever suggested checking fuses in this way. Thank you for sharing this information.

I watched this video yesterday before doing some work on my battery and today I helped a neighbour with a drained battery get her manual transmission car push-started and on her way. Since this video touched on a back door-release hatch not working properly, I looked for something similar when my neighbour's "door ajar" warning light stayed illuminated. Turned out her back hatch wouldn't close properly because of some fender damage that wasn't fixed and caused the door to jam opening and closing. To open it, she would pry with her fingers on one side and pop it open. To close it, she would give it a good slam. However, the electric switch to remotely open the hatchback was accidentally hit by her and since the door didn't pop open at the time, and she didn't notice the illuminated warning light, it stayed illuminated for days until she went to start her car today. Not exactly the same problem as the Jeep in the video but the knowledge gained came in so handy less than 24 hours later. KZfaq University is great!

good tutorial, i learn something from you matt...thanks, other solution is disconnect the fuse, replace it with a 4pin relay, one of the pin of the fuse is constant (+) connect it to #30 (add a fuse) of a relay, other pin of the fuse to #87 of a relay, connect #85 of a relay to ground then the #86 (switch) of a relay to + acc from the fuse box (find one), its just by doing this the body control module wont have power supply when key is off (so it wont draw any power) but when u turn the key to acc or on it will supply power to the relay switch powering it on.

This video is 6 years old but has to be the best troubleshooting video of how to troubleshoot a parasitic draw. I did the one that has been pretty popular of how to locate it without removing the negative battery cable but that one has proven a bust. What I love about this video is you not only show how to set the multimeter and pull the fuses but you then also show how to go to the next step to narrow down where the draw is in case you still end up at a rather broad range of possibilities like the wire cluster that the fuse was connected to which in turn controlled the BCM which would have been a major pain to troubleshoot. Hopefully whatever is draining my battery now is something easy to locate, but better yet, easy to fix.

Just an FYi(cause I didnt see it in the video nor the comments), The Security system relies upon that back hatch being closed, and if it senses that it isnt closed; the Body Control Module never 'goes to sleep' after the system arms itself(3 min after door lock or engine off and doors closed). The late model ZJ's were notorious for this flaw, and many times the BCM burns out because of it.(too many hours being on). I had this issue for some time. The alarm would go off at strange times during the night/day. The fix(if you do not have the flipper glass on the hatch) is a simple $2.00 switch/part that fits into the hatch mechanism. If the flipper glass is present: there is another plastic piece that helps the car know that the window is closed or open. Also quite cheap if you can find it.

@survivalbyJGC 7 жыл бұрын

if the BCM never goes to sleep, you will find a parasitic draw much like what you have in your 98 GC. There is also a quick fix for the hatch mechanism sensor. You just clip the sensor out of the circuit in the rear by cutting the two wires to the sensor(in and out of the mechanism) and simply crimp or solder them together. This fix will always send a circuit 'closed' to the BCM but will allow your rear hatch or flipper glass to be opened whenever without the alarm being triggered. Also a fun fact, the rear locking mechanism also controls the power feed to the rear wiper. If one or both of the sensors in the back hatch are in an 'open' signal the rear wiper will not work. The relay system will not allow the power to get back there for the wiper to do its thing. For other ZJ owners out there: Cherokeetalk and Jeep Forum have tons of info and friendly ZJ owners ready to help.

@bezaleeluk3696 4 жыл бұрын

Finally a commenter that has a clue about why a rear hatch sensor/switch is important and why the BCM should be left operational and not disabled... Is he going to tell his insurance company he's modified the vehicles alarm so it is no longer effective? I doubt it!

This finally helped me solve this issue on my WJ. Mine was the rear driver side door ajar sensor. Confirmed the parasitic draw, tracked it down to connector C1, pin 10. Clipped that wire and the draw dropped to zero. Since I had the seat and all trim pulled anyway I went ahead and patched in a new wire from the panel to the connection at the door. Everything works perfectly again. Thanks a ton dude. Great channel, one of my absolute favs.

Years ago I was replacing a headlight bulb on my Ford. The pos post of the battery was located quite close to the metal of the front fender area. So when I reached between the battery and the fender to replace the bulb my wrist bridged the gap. I was wearing a wrist watch at the time with a metal watch band, so the watch band bridged the gap between the pos post and the sheet metal, creating a dead short and many amps around my wrist. I tried to flip the watch band off of my wrist with my other hand but it was so hot I couldn't touch it. After jumping around and flailing my arms I finally got that watch band off of my wrist. I developed a permanent scar where the watch band went around my wrist and I can still see that watch band 40 years later.

Literally exactly what i was looking for. My 2008 Sentra has the 50 A Fuse drawing 80mA while off and it happens to be the Body Control Module. I was stuck because everyone else is an easy fix like interior light and they just unplug and that's it but you my friend are amazing for this. I greatly appreciate your help.

Great video on how to troubleshoot. I was once a technician at Xerox corp, so I understood what you were doing. I recently replaced my car battery after 3.5 years. I don't drive the car much, so I think that may have been the problem. But I will use your steps to see if I have a parasitic draw somewhere in the vehicle. Thanks!

Your video was very helpful as you spoke in plain English instead of using all of those technical terms . I have a 1997 Jeep Grand Cherokee and the NEW battery drains away within just a couple of days . I also have that 'worthless' factory anti-theft alarm in it that goes off , for no reason , all the time . I think my electrical drain is in the alarm system , and when you said YOUR problem was in the back hatch area affecting the dome lights , I have a alarm 'sensor' in the rear hatch door that maybe is the problem . But Your video showed me How To Determine where the battery drain could be with your 'Fuse Box' test . If my #7 fuse shows the drain , that is my 'factory anti-theft alarm' , then my suspicion was correct . If it isn't , then you saved me a whole lot of time and trouble messing with it . Thanks Man !

Great trouble shooting, very helpful! the back hatch sensor gets out of adjustment inside the hatch, lots of people have that issue... causes the alarm to go off too.

This is a great and informative video, I like the method of testing between the male and female parts of the connectors for current. I do have a question, how would one perform this same type of test on the type of fuse boxes that are hard wired in like some of the auxiliary fuse boxes and some manufacturers also have them hard wired with no connectors

@codyreece7871 2 жыл бұрын

Useful reply but it doesn't answer their question. Just saying I'd like to know how to test them if they are built in. My only answer is to barely peel a tiny piece of plastic off of the wire to be able to test it, or all if it takes it, then just use electric tape around the places you done it, idk just an idea

Before cutting the purple wire you can remove it from the plastic block with a straight pin. slide the pin next to the wire. on one side will be a release letting the wire free from the block

You can do that or just leave the fuse out as it's probably exactly the same circuit he's disabling (NOT FIXING)

@AceBoy2099 7 жыл бұрын

I haven't used all data but I'm sure the wiring schematic you could probably find there would have told you what was on that #7 circuit and when you traced the wire like you did it'd tell you what it controlled, instead of just cutting it you could have unplugged the back hatch sensor pin thing to test it that way, (probably ideal for "important" things compared to cutting and resplicing when it isn't needed) then you don't have that live wire just dangling and if you found a decent sensor somewhere down the road you could just throw it in and be fixed right.... plus the wiring schematic may have gave a clue to where the wires run incase of a break/short somewhere inline that could be fixed.
