Come along with Eric O. at the SMA shop as he has a look at this 1997 Subaru Legacy Outback Wagon 2.5 DOHC that has some problems with the cooling fans and overheating. It was pretty cut and dry really. It had 2 blown fuses. New fuses installed and everything works fine. BUT WHAT BLEW THE FUSE!? That is the question we try to track down in this video so stay tuned.

Haha 😄 . Peeking out 💩 ..sorry jus tryna get a Lil laf.
Nice find Eric O with the wave Forms them motors are definitely shot popping fuses always tell a story great diagnosis Eric O 👍 @SouthMainAutoRepairLLC
Have a good story. My 2001 Avalon had intermittent rumbling/vibration under load generally on the interstate. Took it to a mechanic with a code. He said the motor mounts were bad 3 of them I believe. I let him replace them because I saw them and they were bad. But he didn’t fix the problem. He was convinced it was the motor mounts. I already replaced the tps and maf and some bad tubing going into the throttle body thanks to your content I got a lot of confidence with my own hands. After some more research I narrowed it down to the oil control Solenoid or vvt solenoid ( which ever name you like) and fixed it myself and I won’t go back to that mechanic.
That wave form can ben evened out more with a capacitor. Its a very messy DC load and looks needs a correction cap from factory.
Great job👍
👍✌
Your diagnostics are second to none. Too bad for customers who can't come to you.
I am retired and have lots of free time.I live in CT and am planning to drive to Avoca to see you. I'll call first to make you will be around.
You will like my Maserati!
Hey there viewers and welcome back to the self made auto channel 😀
This is why I watch your videos, other mechanics would replace the fuse and send it down the road, thanks for being you!
Always learn something new.
Very interesting and informative. Thank you, Sir!
If only Doctors used this same method. What caused the cancer?…
Next time just put a 25 amp fuse in it!
Pretty much the same with exception of car quest had Siemens replacement fans that were direct fit for the vehicle
From 0-100%, electrical diagnostics, testing, to a complete fix. You do everything for your customers,,,Thank you.
Stud!
could i ask how many different bulbs do you use for loading and which ones do you use. trying to get setup with different ones
Use the hook amperage draw heater fan motor or whatever fan
This is why I love my 2002 Honda Accord. Aftermarket main fan: $40.79. Aftermarket aux fan: $38.79.
Nice work Eric. CYA!
$600 for Subaru fans? I have a fan in my old Dodge Truck that runs on a belt. The belt costs $20. Maybe we have gotten too complex when it comes to getting from point A to point B.
Second time watching 5/7/ 2020
More good info ERIC. Stay safe ye all.
It's GREAT that you'd get a used part… a lot of guys would tell the cust to buy the new one.. or go get a used one themselves. And then refuse to guarantee ANYthing even labor… lol.
This is a few years old and I am a bit late, but if you ever suspect an intermittent short to ground you can disconnect both side of the wire and put a megohmeter on it and see if the insulation is compromised. Putting 1000v on it will cause voltage to jump any short gaps and that shows up on the meter.
Another AWESOME teaching video.
I like that they have the green connectors to hook up and test relays, that is pretty smart
You said you were not sure why you made this video, well I could see right at the start that this was an issue that needed to be told!! Now I digress for a moment, you are such a humanitarian, I know of no shop that would go through what you do to save someone some cash. With that said, you id a great service showing people why you cannot just replace a fuse and walk away. In my mind as was yours, there would always be the question of why did the fuses blow??? There is always a reason.
Cars almost dead get any old fan small enough to fit wire it in cheap and good enough.
Who were the seven douches that disliked the video? Probably seven guys who would have put in new fuses and shipped it!I did a repair on a private corporate bus A/C system where the system over-pressurized and blew out a pressure relief plug. Found out the cooling fan fuses for the condenser on the roof were blown. Replaced them and did everything we could think of to try and over heat them or cause high amp draw (didn't have a scope at the time), but it ran perfectly for over an hour. Put the cover back in place and inspected it and found that the fan blades out circular edge rubbed on the cover causing just enough friction to cause the motors to start overworking. Cut the cover for clearance and boom. Corporate execs have a nice cool bus to ride in again.
These infos are really valuable thanks for sharing, because you i love cars lol ^_^
There's a world of difference between diagnosing the proximate cause and diagnosing the ultimate cause.
you go the extra mile by finding used fans for the customer.
Eric I've been on a roll rewatching and catching up on your videos, but I really loved this one, because you are teaching a very valuable lesson on finding out the "why"…excellent!
Also, thanks for sharing the waveforms on the before and after…very valuable for learnin'!
If the battery voltage was low the amperage would be higher
Your tagline "If I can do it …" isn't true any more. You do a better job of diagnosis and have a better understanding of what is happening than many "professional" mechanics. Without that understanding being able to take things apart and re-assemble them while following a manufacturer's procedure is not much more effective than throwing parts at a problem.
Before scopes, all I had was the Digital Multi Meter, and of course, my old Sears Craftsman (analog) Meter with the current scale. It….worked……sorta. NOW with the Pico, its WOW! "THERE'S YOUR PROBLEM LADY!" Thanks for this info.
In an earlier video you said you don't get any trollers on your channel meaning people trolling you saying rude stuff. I believe that is because I think you're an exceptional mechanic. I'm a small engine mechanic and I also maintain a fleet of trucks for a water restoration company I wish I had some of the diagnostic equipment that you have. we just don't have the budget for it that's why I have to rely on guys like you when I hit a dead end instead of poking around and making things harder. I enjoy watching your channel you are probably one of the best mechanics I've seen. Kudos.
Eric, you my friend are what they refer to in this business as a, REPUTABLE MECHANIC. I'd let you work on my car, with my family in it! Lol. Great work and with your integrity, you are guaranteed to always have full bays and a full cash drawer! Take care. Jpol. Remember….more old school diagnosis.. Please and Thank you.
thk for the follow through i need picoscope and yes i know this video is old
Eric, I loved this video when it was new, just watched again. It is awesome to find how much you can discover about how it is working while it is working. I watched Scanner Danner do the same with a fuel pump motor, even calculating the pump's rpm by the time base on a pulse width modulated pump. You do great work building the integrity of your trade. Thank you.
Awesome work brother… hard to find honest mechanics..
Great video Eric. I alway think you’re saying, “SELF MADE AUTO CHANNEL”.
When ur hands get too tired to keep wrenching u should 100% consider teaching
Thank you once again Eric for sharing your diagnostic experience. I really enjoy these videos, keep up the good work! California cliff
I went through a few of your Pico videos. I could have sworn you had links to the waveforms somewhere in the descriptions. I guess not a big deal, the videos are still great and watching the scope usage on there.
I was shopping around for a scan tool, taking my time and reading everything I could get my hands on. I've been watching a bunch of your PicoScope videos and I've decided to change my direction. Our shop has an Autel but nobody has a scope. In fact when I mentioned that I am looking for one, i got the ol "well i been turning wrenches 20 years and I never needed one of those….." Well sure, you can use decades of experience to give you a more accurate throwing arm as you play Parts Darts. But I want to be able to prove what I think may be the cause of a problem, plus the real experts use scopes. We may not need it every day but think of the TV show House MD. He was the guy who got cases handed to him after 5 other professionals could not figure out the problem. Anyway, now I'm shopping around for a used Pico on ebay. I already have a good hand-me-down win7 i5 8gb ddr3 laptop which, once I cleared off all the junk, runs very smooth.
Only guy other than myself that I would trust to work on my vehicle…….
Great vid…
Eric, another great video. Without the scope, I'd guess we would have seen roughly that ~20 draw with just the amp clamp. In my mind, I was thinking that that 20 amp ckt would be normally around 80% of that fuse rating, or 16amp. Your fix was well below that. thanks.
Testing with the load in place ! Brilliant! Silly tools not necessary absolutely. Squeezing of relays . pffft. Awesome video again my friend . Keep up the great work
