And the kids thought they didn't have to go to school tomorrow, but Keith came along and messed up their plans🤣🤣

I really like the way you diagnose things, I’ve been burned by a fuse like that before, but it’s definitely not something you’ll forget again!! Thanks for sharing

Thanks so much I always learn a lot from all your videos !!!

Your thinking through diagnosis is unbelievable. Thanks for teaching us.

Great video. Three months ago I had a Freightliner dump truck that had a check engine light,derate mood problem and like eight codes for no communication to bcm, after treatment codes, Def codes, etc. So I kept looking at this no communication codes. Well I checked my fuses and they were all good with a test light. Except one the little leg of the fuse was black. I was like ok. I put a new fuse in the fuse block and the screen on the laptop glinched. All my codes went inactive. They start as active. Once the fuse was replaced. They went inactive. Started the truck up ran great and cleared the warning lights on the dash. But this fuse showed good with a test light and a dvom. The black corroded color is what caught my eye.

The old "NO POWAH" problem. I have seen fuses that were cracked inside and when you poke them they make contact again. Nice job, Keith.

kieth is on the short bus today !!!! dont eat the crayons or lick the windows lol good thing to know ive had salt swell the aluminum on those cheap assed fuses up and it spreads the socket then when you clean or replace it you get a bad connection

I get to watch every vid you pur out today. My day off/ ill...keep em coming sensei.

Thank you for this video. I have a 2003 Express 3500 6.0 liter and have spent two days looking at battery cables, negative ground strap from engine to frame, replaced JCA 40 amp fuses, all fuses mentioning anything to do with ignition, the 125 amp mega fuse. I have new battery cables coming from Rock Auto. Tomorrow I was gonna start looking at the ignition switch, but 1st I'm gonna check fuse #46 TBC ACC (10 amp). I hope that's it. Great video! Liked & subscribed...

Thank you for the explanation and the information that is available on Alldata. I use their DIY subscription and I have enjoyed the information so far.

I had a main 30A fuse in a zero-turn mower once that caused complete power loss, as if the battery was dead. The guy had a habit of leaving the unit outside in the rain a few times, and none of these things are designed water tight. The fuse terminal got a little of the green crusties, built up some sky-high resistance, and fried the fuse and holder to a crisp! She got HOT. Only by removing the fuse could I see that one leg was black, and the green plastic melted, which I presume melted the wire inside right at the leg, behind the charred plastic where it was impossible to see, breaking the connection. That was an easy fix - I just happened to start my diag right there. Literally 5 minutes diag'ed and out the door, and onto the next one. Nothing like an avian bombing while you're working! 😂 Nice work dodging them. 😁

Yup I had a 20 amp that looked ok not broke or burnt in anyway I make it a habit to beep test them Definitely could turn out tail chaser. Thx Keith ! You are da man !

I’m starting to think I’m the only one that uses fender covers anymore. A blob of grease on the forehead,no problem. Jacket elbow comes near a tiny patch of crusty old bird poop and gets all squeamish. A spider on the other hand! I really appreciate your enduring the unimaginable purely for our benefit. Thank goodness for spell check 😁

I've seen fuses look good, and physically check out good (& by ohming), but due to oxidation on the tabs, they would not make a good contact in their slot in the fuse block.

Who's that guy who always gets it fixed In the cold in the rain even in the heat In a shop, on the street dodging bird sh!t Whatever it takes for real it's that boi Keith! Lol

The wheels on the bus go round and round.... well at least they do now thanks to Keith!

The kids were happy today 😂😂😂

I don't know why but cracked me up at beginning when you tried slamming key in ignition and totally missed. Lol

this is why i always use a voltmeter to check fuses, snapon makes a nice test light with a voltmeter built in that works great for this

4:45 is a 2-minute answer to whether there is use for Truth Tables in Diagnostics. I've made a video on this topic a while ago, but this one is 10 times shorter and is quite a bit more compelling.

Soooo school is open tomorrow now?

Thanks I am having a problem with my bus staying on i will check that.

Thank you again cubed. Great job Keith.

Very interesting. Thanks for sharing, Keith. How on earth does a fuse box cover just disappear!?

Interesting. I've never heard of Schoolbus being used instead of CANBUS. You never know what to expect with these older vehicles.

2:03 - Fuse nr. 6 and 2:56 - Fuse nr. 46.

Amazing work Keith thank you

ALL HAIL KEITH THE DIAGNOSTIC KING , ya so hey man could i have used a Loadpro with a snap on vantage on this problem and have seen it thanks for the non stop teaching .

It’s always the fuse,just pop one in and send them on their merry way! Hahaha 🤣

You need to have a couple more hands lol. Great video as always

Nice one! 👍👍👍

Excellent use of available info. Thanks!

Smashed another one.

👍👍

Keith if you put your palm behind the fuse(sit it in your hand) your phone should keep better focus👍

Cheers Keith, Sandy

New Level Auto does the chart work for diesels? I am trying to fix mom's cargo 2006 Express Diesel Duramax, changed the starter, no crank, thoughts?

great video but for CHRIST SAKE get a cover for that FUSE BOX!!!!!!

That's not a fuse box, that's a greenhouse! I've been bitten by a "good" bad fuse before. I don't even know their designation at this point, but remember those weird ceramic fuses Mercedes used in the 80s, with exposed tin elements? Sometimes touching a test light to the spring clip that holds 'em in is enough to regain continuity...

A 13 year old school bus WOW . NO COVER ON THE FUSE BOX ...... DOUBLE WOW

My school bus has accessories on but no crank what seem to be the problem here?

Thanks for the video.

I switched too bussman fuses on my Buell motorcycle. Was having same exact fuse issues. What is the root cause of this. I assumed it was Chinese made??

Been there chasing my tale

👍 👍 THANK YOU

I was looking at the same data only a few hours ago but in GM GDS 2

Key action waa funny

When it did light up on both legs what made you go back to pull it out to see it was blown. 🤔 I'm thinking eh :)

Is there much diagnostic work in school bus world

Keith just a quick Question if you don't mind, Do you prefer All Data or Mitchel wiring diagrams or do they both have their good and bad points. They both have plans for DIYers and Paul Danner uses Mitchel because Snap-On uses Mitchel but I was just interested which one would help me the most. Thanks much ❤️️

My Mentor New Level Auto Keith DeFazio 👍 KNOWLEDGEABLE New Level Auto Keith DeFazio From Nick Ayivor from London England UK 🇬🇧 Good Evening ⏰️ 22:55pm

auto assumes the whole fuse block has the green crusties, I would like to personally beat whomever chose that location. firing 98% of all the engineering departments seems like a good start

is the fuse box cover missing or there is none,, my guess is thats it is missing

spray that fuse box with fluid film and ship it!

Why did it blow?

🖒

No euros this week Keith?

First😎

I would have found that with a water bottle, SURE AS SHOOTIN!!

The plonker who left that cover off should be held accountable for the affect on the safety of the kids...

You seriously need a camera man...lol all these one handed vids 😆😆😆

When you zoomed in it reminded me of the streets of san Francisco..all dirty and lots "O" green all around 😩😩😩😩. I live 45 minutes from SF and i dont like to visit...lots of 💩💩💩💩💩

harbor freight fuse

Pardon me... ...trainee shop? -100

What kind of unprofessional clowns run a vehicle with no fuse box cover? ... They're only somebody's CHILDREN, so why care? What the FUCK goes through some people's minds.

Man those garbage motors vehicles really keep you busy Keith
