Who’s here in 2024?

Nice vid man. It was great meeting you at the Shell deal last week. Your videos are 100% you, and I dig that!

Ironically 95 percent of viewers are definitely not revving up our engines lol

Scotty, I must thank you for all the videos that you have religiously posted and taught me the basics of being a mechanically inclined. I would be nowhere with my project without these videos.

Keep this man safe at all costs

Still being used 10 years later

I freaking LOVE your videos. So helpful and so direct and quick to the point. Thanks for all the info.

Scotty, This video was about staying grounded, no getting lit up... Awesome video, You deserve a couple good swigs...

weak connections, try unplugging them all , cleaning them, and snapping them back together. Pray it's not a computer circuit problem, they need replacing.

What if the car doesn’t start at all???

Wonderful. One of the best instructional videos on vehicle earth fault-finding. Well done.

Thank you so much for this. Seriously, both my father and my brother were/are master mechanics, and both have tried to explain things to me. Some things I understood but some I just couldn't grasp, because like many people they explained things as though they were talking to another mechanic. Your explanations are simple yet expansive, helpful without being condescending. Thank you again.

yes, check your anti theft system if it has one and it needs resetting. If not, check the battery terminals and wires to see if they are not getting power from being loose or cracked

I keep coming back to your videos, Scotty. Great info. I just diagnosed a bad ground wire on the left high beam of my 2000 Nissan Maxima. I fixed it by running a jumper wire from the other light. I could not find the broken ground, but the guy I bought the car off of could not find it either. Lots of light now.

6 years later and this video is still helpful. Thanks Scotty!

you can try the crank sensor, but if you've lost both spark and injector pulse, that's always a bad main computer on that model

check the grounds and the switch itself. If all running lights don't work, normally the fuse or switch

I just went through a similar problem to the example shown here (parking lights come on when stepping on the brake). I followed the "start with the easy stuff" method, and was pleased to find out within minutes that the problem was an internal short IN THE BRAKE LIGHT BULB ITSELF. The brake filament had partially melted due to wear and tear and was touching the tail light filament, which every time I stepped on the brake would feed electricity through the tail light circuit (which illuminated parking lamps and dash/gauge lights, in addition to causing my aftermarket stereo to dim its display due to power on the illumination lead). This was definitely an odd electrical problem I have only seen once before, and I was glad to find it was not a problem with the wiring itself. Additionally, many Saab 900/9000s and Volvo 240/740s are known for tail lamp ground issues - putting on a turn signal would flash alternating between turn signal and backup lamp (one Saab I worked on, the turn signal would flash the brake and backup lamps when your foot was on the brake but act normally when not braking) or other weird reactions as the electrons flow through other circuits to find a better ground.

Wow, simple test. Alas, something the simple solution guy, who may be slightly leaning towards the Mr. Magoo direction doesn't know the two other steps you so graciously provided. Thanks again Scotty.

could be bad wiring, check around the alternator wires first. More often a bad alternator. O2 sensors can go bad many ways, so you normally trust the computer on board to diagnose that and flag a code when bad

I would start by checking the ground wires and the circuit boards back there, on MERCs the boards often warp with age and need replacing

Well now we know why Scotty always seems to be so happy :-) Another good video, thank you.

Thanks Scotty from 10 Years ago, still Helping me in 2023! God Bless you!

could be a bad ground or wiring problem to the alternator. As that belt broke, MANY wires or sensors could have been damaged, check in that area first.

Thanks Scotty; as always good tips, simplified and well edited. You are the man when it comes to make it simple to us, keep up the good work!

Scotty Mannnn..YOUR VOICE IS EVERYTHING THE WORLD NEEDS

I love learner about mechanical and electrical things and you are fun to watch and informative. Keep making videos. Thanks

"You really don't care what its doing when it's sitting there resting" I heard: "You really don't care what it's doing when it's sitting there rusting"

you have a dead short. Do my video "fixing battery drain on your car"

The last 10 seconds of this video helped me lots... To understand why Scotty moved to Tennessee.

"Even I can't see electricity" What a Guy. Dem sneaky little Earth wires - we seek them here, we seek them there

Scott thank you for answering my question you are truly one of the good guys much appreciated

Your awesome, thanks for giving up your time to help us, much appreciated,

thanks a lot Scott you really know a lot about cars. I checked for corrosion in my cars computer and sure enough. corroded green tips. I cleaned it up and my 3 codes disappeared. thanks again you saved me in time of need.

Once again thank you mr Kilmer. I get so sick of people not cutting the fat.

check all the fuses in all the fuse boxes, pray you just blew one, you probably did. If not, start tracing the wiring from the dome back to everywhere to find shorts.

best explanation ever .. keep on bro

Probably the most energetic and positive mechanic I’ve seen

Every time i need to figure out something, you end up showing me the tools i need to figure it out myself

Can a bad ground cause an engine to run lumpy and rough? and even stall out when it's revved

there are many ground wires on that chevy, I'd advise getting a wiring diagram that shows them all

I've got a tricky one for you mate. I just replaced the crank and cam angle sensors in my 6G74 3.5 Mitsubishi Pajero. It ran fine for a week. Now. When I replace the clutch in it earlier last year, my silly mate "who's meant to be a qualified diesel fitter", I'm an apprentice, was in rush and wanted his hoist back and forced the box to the engine and zipped it up with the rattle gun. Resulting in a pinched main engine ground harness that runs over the back of the engine. I tried the best I could to isolate the wires semi blind because of where it was. Fast forward to the current day after replacing the crank and cam angle sensors, and it ran fine for a week. I parked it up. It sat for a couple hours and then we went to go back out for my son, and it would start but not run/idle properly. Like it was hunting for the correct cylinder. I had my other mate bring his snap on scan tool. And the codes said crank and cam angle sensor again. Which isn't right. Would the ground do this?

This is excellent. Very well explained and easy to follow the steps to find your electrical problem. Good job!! 👏

nice moonshine

Man your way to hype I love it 😂

Thank you And everybody else made it so difficult to learn how to test the vehicle grounds

Thank you Scotty, I would have a lot of problems with my -91 Ford Sierra, if there was no Scotty.

hey scotty i have a integra and im having trouble my headlights wont turn on at all after a few wires touched each other and something went wronb i changed fuses but still wont work pls help thnk u

thank you

Why is this guy so easy to listen to? I love his videos!

This really helped me out. Ive been wrestling my rig for weeks. I hit the brakes and the rear wipers come on. I really thought my truck was possesed or something.

Does a short just mean that there is not enough resistance (ohms) in a wire? And that now, to much current(amps) is flowing to a source(ex.lightbulb) and destroying said source(lightbulb) i honestly know nothing about electricity

Is a multi-meter and a volt meter the same? I have a multi-meter. I'm having and intermittent battery drain issue. It was 3.50amps. I pulled the interior light fused and it dropped drastically to .50 amps. I pulled every fuse and I can't get that .50 amps down. So I'm guessing the draw might be in the wiring. Can I use my multi-meter to check volts on a wire. My meter does not have clamps it has pointy sticks only. Thanks.

Video is 9 years old and just now found this genius

I recently wrote that my 1990 Chevy Lumina was dying every time I got to a stop sign or light. I first noted that the vacuum lines going to one of the electrical components was worn out. I also turned the idle set screw to increase the rpm and so far the car has not died like it was before.

love your shows :D think you are super cool :D

What's about tail lights

I have to give props to you Scotty! I find it impressive that you're so responsive to your viewers.

my 1999 honda civic lights flickering when the engine is running also the engine stutters at a certain speed when im accerlerating, but as soon as the flickering stop the stuttering from the engine stop too, what could be causing that?

Hi scotty im having a bad connection on my break lights we did put new bulbs but the thing is they're always on even im not stepping into the breaks

Thanks for the information Scotty. I’m dealing with the dim lights on my 02 avalanche; I replaced dimmer switch and harness and they will work when they want to

Thanks Scotty!! You gave me my next task in troubleshooting my car - talk about weird? I was "just driving along" with headlights on, and suddenly the radio turned itself on! (started playing beautiful music) - - I already was aware of weird, fugitive electrical behaviors, so I tried turning the headlights off, and voila, radio went off. (but it did NOT go back on when i turned the lights back on) BTW I had already set its (the radio) fuse aside, so it shouldn't have been capable of turning on anyways - - also, the right parking lights (Mercedes) will NOT turn off when the car is off - - I appreciate your clue, to start checking for faulty grounding wires . . . . wish me luck . . . . now I am starting to see why this beautiful car was only $1000 Hahahahaha!!!

Change the title from''How to Fix Electrical Problems in Your Car (Ground Fault)'' to'' How to check if your car has a ground fault''.

Best explanation on how to test and find a short 👌

I won’t watch anybody else never again… I wish I had more time with Scott and his videos on things to learn all that I can

So are all metal parts on the car, engine, frame, engine mounts suppose to the have the same voltage reading, as across the battery? Any chance a bad ground can through off o2 sensors? Or would that simply be a bad sensor?

So simple and straight forward.

I didn't think I was going to like your videos, no lie haha. But I've been having problems with my car and I just go to your KZfaq channel and see if there's anything here to help me out. And there is so I appreciate you making these videos. These are very helpful

Thanks for writing back about my 1990 Chevy Lumina. I agree that the idle screw should not be adjusted. Recently though I got my car out of a mechanics shop and when I got the car back the idle was up so high that the transmission was slamming every time I would stick it into gear. The original problem was still not taken care of because the car kept dying at stop lights and signs and it was blowing smoke. I took it back to them and one of the mechanics comes out and adjusts the idle set screw. The car would not slam into gear but it did not solve the problem of dying. I had to smog the car. The smog specialist could not even get the car started without problems and the black smoke was belching. He opened the hood looked to the back of the engine and cut part of the rubber hose going into the MAP sensor and all of the sudden the car ran and passed smog. But when I got it out on the street it still wanted to die at stop lights and stop signs and I had to feather the gas. I finally had an idea. I bet the first mechanic had turned the idle screw to low. So I adjusted the screw just a little at a time and then the engine kept running smoothly at the stop lights and stop signs without dying. So far the car is running like it should for a car that has 350,000 miles running on Amsoil.

It's the last weeks of 2020 and Scotty is now living in Tennessee and still sipping that moonshine! 🤣🤣🤣

He just swigs down that moonshine doesn't he. Badass

I want to say thank you. For this video. And all others. You had been a great help the Las few years throughout my life as a home mechanic. God Bless You and Your Great Family

Scott is the best.. I like his enthusiasm and quite exciting way of demonstration not like other few quite boring.. Keep it up Scotty

Really looking forward to you reply , im so convinced that you are the only one whos gonna get me out of the woods

Hi Scotty, I dont give advice anymore I just search for one of your videos and post that---like weird light problems caused by grounds :) Keep up the good work you are helping a lot of folks out

Ah-ha, MOONSHINE!! Scotty, we all now know why you're always so joyfully peppy in your videos! lol I love your personality--keep doin you bud!

You are an incredible smart intelligent man and watching you for years yeah definitely developed my mental faculty in Automotive .Are sharp hip and straight to the point

This guy is amazing. Extra delivery.

Hie Scott , thank you so much for all your videos your are the best . I own a fiat palio 2003 , 8 valve . The problem im experiencing is , my fan for the radiator was not working then we tried connecting the fan to the ignition line then failed to complete the task , the very same day we did this we later had problems in starting the car . The mechanic advice me to get an auto because he said the car has now developed an electrical problem . The auto came he changed some spark plugs then the car start and he then connected the fan on the ignition line .i only drove it for a day . The following morning the car didnt want to start again and i foned him . He asked me to check if the fuel was coming to the engine proper and he told me to first listen to the pump , if it runs the the car start which i did and the car drove and at time i should aso unplug the cold start switch . The car at times would not start then start after a long crank , then the auto said we have to change the petrol pump because it is packing up . We changed it and installed an universal one . The pump sometimes works and at times does not work . After i watched a certain video of why a car cranks long before it start i found that i had to change the petrol filter which i did . Then the car start as i was driving it i noticed that the car is now straggling going uphill then i had to ingage to lower gears to complete the uphill , drove it only once . Now the car doesn't want to start . Pliz help

Thank you sir. You have saved me countless hours of troubleshooting! And could I get a sip of that shine!?😁

Great information Mr Scotty. You made this in its utmost simplicity

Thanks for giving an example about the 4/10ths of a volt difference, I always have problem with those things. 😊

Such a great video. You made it sound easy. You are a good teacher. Thanks for sharing your knowledge.

dude you are like the super nerd of cars, I always learn something

What if my car isn't running yet due to the ground issues? Technically it runs, but the starter won't stop cranking once started. And it labors cranking

Massive help, especially opened my eyes to the fact cars have grounding connections in the trunk! Any others I should know about? Water got in my car after a hard rain, basically a puddle in the passenger side of the car, now the seat belt fault light keeps flashing and beeping, even if no one is sitting in the seat, also turning on the headlights causes the beeping to stop or act up intermitently, any ideas? I did clean and use dilectric grease on the connector under the seat with no fix

also had battery checked again and is fine and the battery terminals are and always have been completely clean. I have also checked out many grounds and everything seems to be in quite good condition besides everything else I told you. alright thanks.

Awesome. I got a 2000 Toyota Avalon that's infamous for electrical problems. The instrument panel and interior lights flicker when the car is running. Hopefully I can figure out what's going on with this

Now I know why you went to Tennessee, you like that moonshine!

Trial & error determined Exposed wiring front park light inside headlights assembly 2008 Lincoln Mark LT after a fender bender riped my headlight off kept blowing fuses all wattages for taillights aka park lights & license plate lamp . Saved myself some bucks

Gentleman, and a scholar.

My car won’t ignite and also the car was good too drive but then my signal lights were completely out.. any idea what’s the problem?

Going to try this right now

man you're simply great!! all the best for you and thank you very much from the end of the globe

Not a bad idea Scott's moon shine hell yeah.

Thanks for your channel. I now know what my problem is. It is a loose wire in the grounding system. They tried to tell me the car needed a new alternator. BAH

I wasn't aware that Lyle Tillman had changed his name to Scotty Kilmer. Cool, dude.

finally I get some use out of Scotty Kilmer

That was an outstanding explanation. Thank you. I kinda knew it but obviously l didn't. Could use ole smokey right about now. cheers.
