Chevrolet Truck - Battery Dies Overnight - Part I

Well we have seen this more than once but we still need to test it right?. Let's have a look at this 2003 Chevrolet 1500 that has an ignition off draw (parasitic draw) Place your bets: Radio, Cluster, Alternator, PCM, or just a bad battery!?!?

[@born_again_torinos]

This is the first video of yours that I have seen. My 2003 yukon has the same key off draw. I have to compliment you on your teaching style and clarity. I learned so much watching you. Well done.

[@DirtyMuthaFugginD]

What was it that you found? I also have a 2003 except it's a tahoe. Also at 201,000 miles on it and it's got a parasitic draw that's killing me. I've already done a new red top, alternator, checked fuses and relays and I've got my hands in the air. I've been a long time chevy builder and mechanic but I am now in the beginning of the 4th stage of c.t.e and my cerebellum is at 5.0 pushing through the back of my skull into my spinal canal and I'll be damned if it isn't screwing with me. Thanks for any help or advice on your end.

[@born_again_torinos]

​@@DirtyMuthaFugginD I've had two different problems. Solved them both. The first was the BCM (body control module) went bad and was saying the hatch was open. Since it thought it was open and it wasn't, it turned on all the interior lights and would drain the battery. I'm not going to try to replace that module so I simply pressed the button by the light switch that prevents the interior lights from coming on when you open the door. Problem solved. Then the other day the door dinger started going off as if you left the key in the ignition and opened the door even though I did take the key out. I read another guys comment that he had read several articles about it and that two different sources said to pull the "radio" fuse under the hood and put it back and pull it out a few times because of possible corrosion and their door chime stopped. I tried it and mine stopped too. Thank God for the comments section.

[@DirtyMuthaFugginD]

@@born_again_torinos thank you! I'm going to check all of these options. As soon as I figure it out I'll come back and share my adventure 😜 I appreciate you!

[@juliantolley2191]

Just to say thank you for highlighting the voltage drop across fuses. Helped to quickly diagnose the draw on my 2003 Chevy Suburban. For all those useful with a soldering iron its very easy to resolder every joint in the instrument cluster. I went from a range of faults including a ghost main beam light that would illuminate despite the car locked and definitely asleep to no faults. Easy to remove the cluster and pop the covers off the cluster.

The ever elusive intermittent fault, I spent several years overhauling electronic equipment at an Army depot and always hated these. Eyeballing the same issue on my 2004 Silverado, the cluster was repaired just before I got it but it began acting up again after about a year. Great video, it gave me some good insight on how to approach the problem.

[@antisocialjusticewarrior2073]

I got an 04 2500 something similar going on.. 2nd battery not charging, but also thinking it could be the BCM. I hate all the electronics

[@Zslowzr1]

You are thorough, systematic, and have a magnificent knowledge base of information. It's funny, because I've been working on cars for about 5 years now and I'm at the point where I can tackle most problems. All on youtube. It went from Chris fix, to ratchets and wrenches, to eric the car guy, and now to you. Because when I first started watching your videos, a lot of them were hard for me to understand,. It's almost like it was the intro class, then the intermediate one, then the more advanced one, then the final one which is your videos. Who needs school when you have youtube!

I googled these same symptoms for my 01 Suburban and this video was suggested. I'm going to go check out my cluster fuse tomorrow morning. Thanks for your videos.

[@Maxify08]

Another nice job, Eric! Getting up early and editing vids is a gift to all of us.

[@72bable]

Your suggestion of reading the millivolt drop across the fuse and converting it using Powerprobe's charts is fantastic. It's not only quick and easy, but also keeps from accidentally activating some system. THANK YOU Eric.

[@timb0man]

Outstanding video! I was able to follow your logical leadings, and though my problem was the radio fuse and not the cluster, I simply bought a clamp meter for autos from amazon and this morning found the battery drain parasitic draw. Thanks a million for posting this.

[@reneewiseman4534]

Love your methods and your persistence!Awesome stuff,keep up the good work!

[@stephendee7839]

These clusters are pretty easy to fix. There are a few surface mount resistors that come unsoldered. Taking the cluster apart re soldering the bad ones and putting it back together takes 30-60 minutes. The bad resistors will brown the board a bit so they're easy to spot, but re solder them all.

[@buzzkiev4135]

Dude you pegged it ! Been having the same issue with my 2001 Chevrolet Suburban 1500. I did what you did and came up with the same issue with the cluster. Thank you for sharing the info for United Radio. I contacted them and the conversation I had with everybody on the phone with United Radio what's like I was talking to Old Buddies! Very pleasant people! They did say they wanted to contact you to thank you for spreading the word as I told them it was your video that help me with Diagnostics and referring everybody to them for repairs ! Thanks again

[@michelewelk2751]

Eric U Rock :) These videos and United Radio saved my dying 2003 Tahoe...runs like a charm now...THANK YOU

[@bchrisl1491]

I am amazed at the sensitivity of test gear these days. To measure the voltage drop across a fuse is truly remarkable. The one you measured, with 202ma and a drop of 1.5mV crunches to a resistance of .0074 ohms. There was a time you could only measure that with a laboratory meter. Waiting on part two.

[@scottlaster1763]

Always enjoy your straight forward diagnostics. Your name is always on top of the list when I tell other techs who to watch to try to better themselves. I had missed this one. Great work Eric.

[@larrypayne4193]

Found your channel while trying to solve a problem with my 2015 Chevy Pickup. You do a great job with these videos. My issue is that this truck, freshly out from under warranty of course, decided to keep the buttons and knobs and the LCD screen back-lights, and the On-star light powered up - and there was no way to get them to turn off. Of course it ran the battery flat over night. I charged the battery and began using your methods to diagnose the battery drain - except that I don't have access to a clamp-on and so I hooked a meter in series with the negative battery cable - it appeared that I had a 150 milliamp parasitic battery drain - at least I thought that I did. So I checked across every fuse in the engine compartment and both fuse blocks in the cab and found a 1.2 millivolt drop across the fuse for "Body Control Module 1". So, the reference you provided a link to showed that the equates to 163 milliamps. I was pretty excited that I found it but I had not noticed that the dome light were on and when they timed out the 1.2 millivolt drop disappeared. Somewhere during all of this I apparently had the battery disconnected and/or the flat battery which caused the issue with the back lighting staying on issue to disappear. What followed on the initial restart of the Truck blew my mind but you will know all about this - the Truck told me to lower and raise the Driver's Side Window! I suppose to reset Body Control Module(s) - the manual says there are seven or eight of them and each one has its own fuse but I suspect there are all housed in the one unit located under the steering column area. Then I discovered that the Tire Pressure Sensors were not being read and the manual said I had to initiate the "relearn" mode and then use the "Tool" by placing it next to each of the tires and sequential order! By this time I'm talking to myself and wondered aloud - "what tool and where is it".. LOL ... but once again you were right there with a way to relearn this thing without a the "Tool" or a trip into the tire store or the dealer. I suspect the original problem will return - things like this usually do. I going to have the battery tested - outside chance that it's getting weak and may the infamous "Integrated Body Control Module" doesn't like it. Once again.... thanks!

GM should recall the instrument panels in their vehicles, my 2004 Chevy Tahoe required a new instrument panel at a cost of $600. Our 2003 Chevy Silverado 2500HD panel is shot as well.

[@feeneysmechanical6215]

Great Video Eric. I see you fixed that powerstroke. Nice job

[@jonbarfield4915]

DC Amps. can be measured by pulling the fuse,then set your meter to amps(you have to move the leads on the meter also).don't keep in on for very long or you can overheat your meter etc. Those capacitors on the amp. meter dry out causing problems. second the new vehicles have to many modules(cars are on live support).

[@dslsdad1]

Thanks for putting the mini fuse conversion chart up. Saved me the trouble. Can a blown fuse draw electricity? Had a blown 20amp mini drawing 1mV. Replaced it and went to zero. My battery was dying after a day or two. Gotta let it sit and see if this was the problem.

[@olittlefield1987]

Great video. My 03 had a similar problem. When ignition off the parking brake light was still faintly on all all the time and the gear position indicators don’t work. Pulled the fuse and light went off. Will be sending in for repair.

[@garyjohnson2879]

wow, over 200,000 miles and it still looks good

[@randywalentoski551]

I have a 04 suburban and had a battery drain that would kill the battery overnight. I narrowed the problem to the gauge cluster. Replaced the entire gauge cluster and problem fixed!!

[@remowilliams623]

All you need to do is unhook the negative cable from the battery and plug a test light between the negative cable and the negative post. will should glow a little, if it's a bright light start unplugging fuses, when you pull the right fuse and the light goes out, you have found the problem circuit, that is causing the problem.

[@johnchristopherson2718]

It's Awesome that you take the time to share your experiences with us. I have a quick story(I only heard about I don't know if it's true) that I'll share that may help others... Customer's car would go dead overnight every night, but only in the fall/winter months of course all of the usual things were done to no avail, finally after going to customers house to observe any abnormalities, they (allegedly) discovered that the customer would put a cover on his windshield,and he held it in place with some small bungee cords, he hooked the cords to the door handles which turned the illuminated entry lights on. I don't know if it's true, but it is a good story.

[@geraldwilcox2427]

I have a 1998 1 ton chevy and the battery would go dead in 2 wks and then finely 2-3 days, found out with amp meter at fuse box that the problem was the memory of the radio causing a 2 amp draw. Replaced radio and no more problem. There is 2 fuses for this radio. I will watch to see what you fined.

[@GNX157]

I haven't finished watching the video but wanted to interject one thing for those watching. Not putting the amp clamp around the cable going to the starter could be a mistake on some vehicles. Some older vehicles specifically GM, have what's called fusible links that come off of the hot 12v post down on the starter, so if the power drain is coming from one of those fusible links you won't be measuring it with the amp clamp.

[@user-jr9vc6uj7l]

I bought a truck for my brother-in-law as he is one SSI and his truck was broke down and it would cost more to fix it then it was worth. We bought a used Chevy SUV that was in very good shape. It ran good, had good mileage etc. but the battery would die in a few days. I replaced it and check the alternator which was good. Could NOT find the problem so I took it to a garage I have known for many years. He said on the phone, "I have to remove the dash, Something is wrong in there and I can get to it" so I said OK,,,even though it would cost ME over $300 in labor. What he found was a GPS locator wired into the "Continuous Hot" circuit. I took it back to the dealer but they refused to reimburse me for the cost. It DID solve the problem though. Took the GPS locator to a friend in the local PD and he said it was a company car and the GPS was there to make sure the driver didn't use it for personal use. He did however say it should NOT have been wired the way it was though. Odd.

I presently don't have this issue, but part of my cluster doesn't work anyway. its original as far as I know, haven't pulled it to check. but I am going to check that voltage drop. I do have a problem with the key switch, sometimes it stays on after the key is out, I can pull it out while its running. lights in the dash will stay on, or the radio stays on.

GOD BLESS YOU ERIC

[@waltschannel7465]

Very cool site that shows you current draw for the millivolts across the fuse. Would not have thought about that! 29:20 Magic wand, LOL. Maybe if you wave it around Harry Potter style, it'll find the current draw? Interesting that the trucks have cluster problems. We had a 2001 Buick Regal that had a bad cluster (no dash lights) at 30K miles. When it came back from the dealer the dash lights still did not work. Sent it back and the headlight switch had gone bad, or so they said! 😁

[@michaelspeakman8924]

check the door locks. Just turn the key to see if it locks because it acts like the security system is enabled. But they should have a drain stop on the battery even the old 1999 Buick had has a drain drain stop

[@MattsRageFitGarage]

Here's a special one for ya. A friend of mine has an 03 avalanche 2500 with the 8.1. That thing developed a 140-milliamp battery draw on it. I can't find it. I've pulled every fuse, relay, and almost every wiring connector and also disconnectd the BCM that truck has and the only change I saw was a 10 milliamp change from the radio. I also checked the power seat motors and no lights are staying on. I even disconnected the alternator and starter with no change. Everything on the truck works, and the instrument cluster was rebuilt last year. The weird thing is when you put a brand new battery in it, everything works fine for a week or two, then if it sits for a few days it's usually dead. After about 2 times of that it'll kill the battery to the point it won't take a charge or even a jump start from another running vehicle. Exchange battery for another new one and it fires right up. I've even pulled on the wiring harness throughout the truck and can't detect a change or find any bad wiring that's been rubbing on something causing a bare spot. The truck is very rust free and I didn't find any corrosion in any connectors either. Got any ideas on this POS?

[@watchdogu.s.a.8973]

Did you ever find your problem on the Avalanche? I have a '99 Chrysler Town and Country that was discharging and I couldn't find a problem even though I was reading a voltage drop. I cut the terminal ends off the positive and ground cables and put on new terminals, cleaned the battery posts exceptionally well, and now... no voltage drop. Odd indeed.

[@MattsRageFitGarage]

@@watchdogu.s.a.8973 It wound up having a bad alternator that was putting out a/c voltage and was frying batteries. A new alternator solved that problem but it still has a drain on it nobody can find.

[@watchdogu.s.a.8973]

@@MattsRageFitGarage Have you tried voltage drop tests and totally removing the fuse for the offending circuit for a couple days to see if it stops?

[@MattsRageFitGarage]

@@watchdogu.s.a.8973 Yep, did the voltage drop test twice. I even disconnected the starter solenoid and electric seat motors just to rule those out. Nothing has made any change.

[@44090mds]

I had a similar problem with my '06 Yukon XL. The battery would repeatedly go flat after several hours when parked. One morning after parking it, I happened to notice that the parking lights were on. I have the automatic headlight feature, and generally leave the switch in the AUTO position. I swapped out the underhood relay with that for the fog lamps, which are activated with a pushbutton having an indicator light. I normally leave the fog lamp switch off. The draw-down problem went away.

ToughAncientSpark I have had one of those since I was a kid, plain long rifles don't kill woodchucks over 75yrds very effectively.
