ISSUE FOUND 2013 F-150 parasitic battery drain...it's the rear defroster relay slot on the bcm that houses the relays on top of the engine compartment. Ford issued a warranty fix for defective rear defrosters for 2012/2013/2014 models...so most of us are past the warranty period. pull the rear defroster relay (40A), and you're battery drain problems are gone. I just came through this problem by trial myself.

I've been told many times that I'm the best mechanic they've ever seen, I tell them to take that and a dollar and you still couldn't buy a cup of coffeee.. I'm 'ol school', love the mechanical aspect of it but will try anything to get out of messing with automotive electrical. Yet I can builf wiring harness for tractors and equipment with no problems. Watching you at work has really helped me. Of course I do not fully understand these 'new cars' with there miles of wire and little small electrical parts that cost off the charts but I don't shy away anymore. You've shown me a lot, changed my perception about electrical and I just wanted to say Thank You for what you do. I don't do much repairs anymore, I'm coming up on the 5year anniversey when the doctor said lung cancer and gave me 'about 90 days', the Lord show him different and I thank him each day. Just not the same as I was, the cancer, chemo and radiation took its toll, I want to return to work but my beat up body says nope, lol......I just 'tinker' these days. Anyway, thank you again sir, you do more than you know, you are a blessed man.

Watching my Dad growing up is what got me interested in mechanics. I find watching someone who knows what they were doing enough to get the right answer without part swapping and not a bunch of hype or screaming is just as enjoyable as doing it myself. The payoff when you hit the key and it starts, nothing else like it.

EVERYONE part swaps still. If a mechanic tells you any different they are not telling you the truth. 😂 Even the best STILL have to part swap sometimes. We just don’t do it quite as often as the shade tree mechanics 😂

Nice to see a real mechanic diagnosis, instead of parts replacing.Love your vids bro,keep up the good work.

I have this same problem right now. My battery has died 3 times in the last week. I checked my alternator today after sitting for about 3 hours and it was hot, 126 degrees, 6 hours later my battery was dead again. I'm having my alternator changed tomorrow.

Eric, Another brilliant diagnosis on your part! You always use good logic and the correct tools. And I always learn from you. Thank you! God bless and happy Fathers Day! (Give your Dad a big hug - mine is in heaven) Paul

Great video! So many mechanics just throw parts at problems instead of taking the time to troubleshoot the root cause! You're the man! Thank you for the detailed troubleshooting. A man after my own heart and detailed regiments!

WOW...thats dedication to a problem...your customers are very lucky to have you for their mechanic...GRATZ

Very nice diag Eric. Shows that it really pays to be diligent and not just throw a bunch of parts at it. Wish I could find a mechanic/technician like you.

This is the perfect case of it does it for the customer not the mechanic. I am so glad you made it happen. I know that customer will be really satisfied. So hard to solve what doesn't happen for the mechanic. You did it. Great job.

This guy is my favorite youtube mechanic because he actually shows you and explains what he is doing, and why he is doing it. All the other ones just talk and talk but you really don't learn anything.

Further adventures with Dr. Eric O and nurse Hannah

My brother had that issue and ended up selling his Ford pickup, now I know what the issue was thanks to your patience and knack for knowledge as to why things do what they do. Such a great channel, mechanic and person.

First time I have ever seen something like this! Good job Eric O!

Love your videos, appriciate how thorough you are and your explanations arent full of BS or waffle. Many thanks for posting

The great lesson here is that assumptions based on prior experience are good, but don't let them drive the diag away from what the data is showing, and what is ultimately a simple fix.

I found your channel over a month and although I'm not a mechanic, I do enjoy your videos. I work 24 shifts and they make my shifts a lot less boring..

I had a craptastic day today (we all have em' occasionally) but the SMA video was sure to put a smile on my face.

Right on. That's 2 for 2 man. Fixed my corvette hot no start and my f150 overnight battery die. Thanks again. Keep up the good work. You have a guift for thinking it through. :)

Great video, thanks for hanging with it despite having so much going on around you!

I like how you admit you made a mistake in your adventures to find the problem. Some folks are too cool for school and their ego's get in the way. Instead, this type of work is a treasure hunt and yes, one goes down the wrong path a time or two but you stuck to it and found the problem and the solution.

ERIC,excellent find and thank you for what u do by taking the time to show this.cheeeeeeers

Bruh. How you not gonna come back and tell us what the problem was......

I've heard of this happening, but never seen it. Sweet diag Dr. O. Thanks!

I've seen this before, back when I hung out with some Ford gearheads in the mid 90' to early 2000's. It would take a few battery replacements before we would come back a few hours later and find the alternator was warm when it shouldn't be. I guess having a bunch of large diodes exposed to heat and the occasional "oopsie" wiring shorts caused the diodes in the rectifier to stop behaving. We dubbed the condition "Diodes gone wild".

Wish your shop was closer to me, you'd be one of the main shops I'd take my vehicles to. You thoroughly investigate the issue and get it right the first time. Also I can tell by your bits of humor that you still enjoy what your doing and want to share it. I truly wish you the best of luck on your channel and business. You're the only automotive repair channel that makes learning about cars fun for me, keep it up. I'm about to put a new battery in my f150 but going to double check for extra draw upon reinstallation. I'm positive my problem is the battery since it is about 8 years old, I just want to be sure nothing is going to drain the new one.

You Sir,are a troubleshooting guru...THUMBS UP

Awesome job Dr O wished all mechanics was as legit as you buddy!

Had this happen to an old Pontiac I had. Turned out to be bad diodes in the alternator that caused a parasitic draw. Good diagnosis Eric O!

Congrats for being mentioned by the Trained by Techs org and named as a Top Gun! Keep it up.

I was a Ford tech back in 99 to 06. The majority of ROs on the pickups were draws, and 90% of them were fuel pump relay or popped diodes in the alternator. Well done bro

Absolutely one great video Eric. Enjoyed every minute. Yes both cables should of been clamped. And why it took so long to start the parasitic drain baffles me also. I see a thermo imager tool coming soon. You deserve it. Thanks for all your help Dr. O

Great video Eric, like the way you described the total current drawn by the bad alternator, not only from the Main feed to the battery but the 12 volt sensing line to the battery fro alternator. Awesome !!! And thanks.

We all make mistakes but overcome them. Great videos! my gm had a 2.66amp draw with your videos I was able to find the issue which was the factory amp staying on with the key off.. I don't have the pico scope but I used a mulitmeter wired it to the battery in series and dropped down to about .066 ma..which is relieving for me..when I bought the truck it was neglected and it was a work truck..so im tryin my best to make it perform as it should. Anyways great videos. I love your content. Feels like im a part of them. Keep up the great work :)

Brilliant video, I learn a little more every time. Thanks.

I think he is great! He always explains when he is doing something. I like it because there's no guessing.

GOOD ONE PLEASE KEEP IT UP ALWAYS LOVE TO SEE DIAGNOSTIC VIDEOS AND THANKS AGAIN !

Hey Erick another great video diagnose. I replaced my battery when my Opel/insignia didn’t/wouldn’t start it was only 2 years old But kept draining overnight. Love how you explain stuff great content

These video's are better than murder mysteries

Really enjoyed this one Eric - many thanks.

Most of the time on 2009 f150 I find the drain is because of the PARK interlock on the column. If the light under the "P" is NOT on while in park, this is your problem and it is a very easy fix.

Awesome! They'd be insane not to give you the job. It's much safer in your hands.

It is so interesting watching how he gets to the problem!

Good video, thanks for making it. My short turned out to be in the CD player. I disconnected it from the radio (ribbon connection inside) and it solved the battery draw.

Excellent video Eric. I'm no mechanic but I work on my own stuff, well I try to.

No need to apologize you are working, I'm learning.nice to see a normal person

nice one Eric.Your current video that is!

Thx for your assessment Eric, helped me out. I was chasing my tail. I have a 2003 F150 with same problem. Bought an alternator from a salvage yard. Had it checked out and amperage was good. Must of had a bad diode. Don't be cheap people, buy a new alternator!! So I just disconnected the alternator and BOOM, no more draw! Problem fixed. Thnx Eric, you gave me a direction to go in. Happy again😀

This is the most educational and entertaining guy I've seen with auto stuff. Thank you for the video. Im on the hunt for my electric gremlin in my 2012 f150 eco boost. Been going on for 2 years. Been through 10 batteries, thanks to life time warranties onlu cost me for 2. But no shop had figured this out.

Love your channel and your video's. You actually trouble shoot and not just as you say, shoot the parts cannon at it. Thank you for the all the good information

Had battery problems on 2006 Corvette. Turned out to be headlight relay. Overnight the headlights would come on and drain the battery. Said something to my neighbor about dead battery, he said that when he went to work at 4:30 am the headlights were on. Replaced the really trouble fixed.

Thanks so much for this. I have a 98 F-150 that's doing this exact thing.

I so enjoy the "Hunt" ! - Sherlock Homes would give your efforts 2 thumbs up.

I like that you don't just edit mistakes out; we're only human after all! I'm an IT guy and I made a mistake the other day replacing a duplexer in a printer. I noticed it wasn't sitting flat before I screwed it down which I should have taken as a hint that something was wrong, but didn't. Luckily it had another issue and when I came back it kept jamming on duplex printing. I inspected and noticed a piece of plastic was behind a part of the duplexer instead of in front, which was causing the jam. I removed the pick arm assembly, removed the duplexer and reinstalled correctly. This time, it layed down flat nicely with no issue. Mistakes happen, always learn from them!

I am having the same problem with my truck thank you for solving it

Great job Mr. O. Hope for another great video soon

Eric I just want you to know your videos have helped make me a better tech and thank you. You would do the tech community a great service if you could teach an occasional class at your local vo tech because I feel like proper electrical diagnosis skills aren't really being taught to younger techs these days.

I'm a 62 year old tech, and the fancy equipment slowed you down. I have that stuff as well however with any Ford the alternator is almost always the drain. The diodes go bad and if you remove the belt,, you will see the alternator has turned into a motor. Many times the alternator will keep the engine spinning if its shorted the right way, yes with that small of a pulley it will turn the engine.. Some things seem to never change. Thanks for the demo, try my belt off alt turned to motor. Kind of cool!

I’ve watched this video four times. Keeps coming up in my feed.

Great job Eric! I had the same problem with my 78 trans am , I was chasing a battery going dead and by chance I brushed up against the alternator and it was hot . There’s not many things that can cause a draw on that car tho like the one you were working on lol. Difference kennel of fish all together but great diagnostic work on your part!

Ha!! I got one in today with same issue! Thanks Eric

When you do a Good analysis ,you get good results. Alway enjoy your approach to a problem.

Hey Eric 14:58 minutes when you plugged in the alternator Smoke came out of it! LOL Good Job

You, my friend, are a very skilled diagnostician and mechanic. Are you self taught? Keep at it. You'll go far. I love to diagnose but I hate to wrench.

I was fascinated by the steps you went thru in order to make the diagnosis. Like most technicians you are a jack of all trades-electrician, computer tech, and-nuts and-bolts wrench man. The technicians ability to work these three fields was recently demonstrated when the same tech who reformatted my infotainment screen on my Taurus also replaced my rear rotors and brakes.

You the man Eric! THE MAN!!!

That's was and amazing find! Thanks for sharing. I am having the same problem with a 2013. but does it about every 4 months or so.

Great video, great work!

Great job like always.

Good job Eric

As for the previous auto shop firing the parts cannon at it, you'd think the alternator would've been replaced with a battery charge issue. Makes me wonder what that garage charged $500 for. How unfortunate for the owner. Good job providing a properly identifiable diagnosis. Now I got some ideas of why my Ford Five Hundred's battery goes flat periodically. Cheers!

You find and fix some tough problems good work

must correct you on your quote"if I can do it you can do it" Sir, nothing can match your training, years of experience and technically devoted to keep up with technology except an = to training, years of experience and so on...you are the teacher we are the students. Respect!

Hi Eric You are definetly a master mechanic. I really enjoy watching you perform your diagnostics You still use your (EENH) as my ncle used to call it Eyes Ears Nose & Hands and your brain. Always look for something that seems out of place and do not forget the obvious. Great Video and the confirmation from the modern test equipment and knowing how to use it well is another credit to you. Keep the videos coming please.

Great job!

Super vid! Thank you Eric!

I have a possible answer as to why the amp draw was "delayed" by several hours. As the alternator cools from normal running temp to ambient temp, the components/windings within the alternator slightly contract allowing a short. Also keep in mind the alternator winding is coated with epoxy, which can crack over time due to heating/cooling cycles. This can also allow shorting. The owner did not notice this, nor the other shops, as the vehicle was probably at running temp when checked. Without closely monitoring and tracking like you have done, it likely would have never been discovered. Another great job by South Main Auto. 👍
