Auto Repair Do It Yourself?

Good afternoon. My name is Tom Brunch snuff, but certified mashed mechanic from Redding, Pennsylvania. And today we’re going to learn how to troubleshoot car stereo speakers.

So if you’re not sure how to take it off, get yourself a repair manual, local parts store, I think they’re like $12 or something like that. So a lot cheaper and breaking a door panel. Um, once you get your door panel off, locate your speaker or speakers and your door. Um, if you got a speaker that’s cracking the noise is a little distorted. Chances are right off the bat you’re gonna need to replace that speaker.

Auto Repair Do It Yourself Auto Repair This particular speaker here isn’t working at all. Um, so we’re going to go ahead and take the speaker out and I’ll show you how to troubleshoot whether or not it’s a speaker or if it’s actually radio or the wiring. We’ll go take these couple of screws out or have to up a map. I’m going to take these last two out here. Save a little time.

Try not to let speak or fall out of the door. If you, you’ve got a good speaker. The last thing you want to do is poke a hole in it, unplug your, your speaker in the back. There’s a little tab that usually holds remain. Just push it in, pull it right out. You want to set this on a diode section or voltage sensing. If you’ve got a signal at this thing will automatically beep on you. There are two wires in this plug.

It doesn’t matter which way you hook these up. As long as there’s a second, a little beep at you, you plug it in, it’s beeping away. You know you got a good signal out here. Next thing you need to do is just replace your speaker reverse process, but you knew when an and you’re good to go.

How to Diagnose a Car Electrical Problem

Today we’re going to talk about the basic procedure of diagnosing an electrical problem. Um, sometimes something in your car won’t work and you need to determine why. And in most cases it’s either an electrical supply problem of some kind or the component itself doesn’t work. So the component itself we refer to as an electrical load. So a light bulb, the part of a circuit they’re supposed to do the work and making light is a load. A motor could be another load as well. So on the first step that you’ll do in these circumstances is actually go to the load and find out whether you’ve got power there. Some cases you’ll check the fuses first, but it’ll depend on the accessibility of the load. In this case, the load is pretty easy to get apps or we’re going to check that first. So what we’ll do is we’ll take a typical automotive test light and we’ll hook it in parallel with the load to determine if there is the presence of both battery power and ground.

So in those case, I can see where the wires come in and a and a light circuit like this is pretty simple. So we’ll first take and hook it up to growl lead on one side and the first slide on the other and it won’t make our test light up. So that’s an indication that there’s something missing so that we need to determine what it is that’s missing. And this case, I have um, a tool that is hooked up to the battery directly so we can determine if we have power or off. We have ground in this case I hookups or growl connection.

we do have ground on the ground wire. Um, red, uh, it still shows the ground. So that’s an indication that we do not have bought a battery positive, making it to the load itself. So we need to, uh, check upstream. In this case, we need to check the fuses are next step process is actually the check the fuses in the car as I’ll remove the top of the fuse cover, uh, to gain access to the fuses inside. And I’ll demonstrate in this case this type of a fuse has two little test ports where we can check and see what we have for connection.

Well, we checked the fuse for the suspect’s circuit. Um, we find in this case we check one yeah bad fuse. So if we remove that fuse and we’d take a look at it, we can see that there is actually a missing gap of fuse, a fuses designed to melt when too much current flows in a circuit. And Ad appears to be what’s happened here. So in this case, we’ll get another fuse and reinserted.

Now have battery positive on both sides of it. And, uh, the, uh, trunk light is, is returned to working. Uh, but that’s not actually the end of the story. If users don’t blow for no reason what we have here as an intermittent short, but that’s for another video.

How to Buy Fuel Treatments

Good afternoon. My name is Tom Burns snuff. I’m a certified master mechanic film bedding, Pennsylvania. Today we’re going to talk about how to buy fuel treatments. Now, mark, we have today you kind of get a little confusing. You’re walking or local parts store and I was just shelf after shelf of different fuel treatments. Um, a lot of them do basically the same, same function. There are differences amongst them and I’ll go over them a little bit. Here you have three separate fuel treatments for diesel engines, all of which do basically the same thing, but some have, this one’s basically removes water on a few of the diesel fuels jelled up. This is a good one here. This one’s an octane booster here depending on what you’re looking for if you just don’t get in the power that you want to have your diesel engine, this is a, uh, a supreme product right here.

Um, just, just a condensed conditioner and anti jail. As I said, it all depends on what, what purpose you’re looking for. If you’ve got a gas-powered gas powered engine, you just looking for regular fuel injection. This product right here, two plus two from Burchell works excellent. So intake cleaner, fuel injection cleaner if you’ve got water in your fuel system. This ISO dry works good is there are tons of different products that make the same thing. But if you have a water problem, ISO drive works for Y’all. Good. Um, overall the best product I’ve found so far is from Lucas. Lucas makes a ton of products and the supreme in their line, but uh, this one pretty much does just about everything. When it comes to a gas motor dump. One of these in every other time you get, you get your gas stream and it cost about four or $5. You get local parts store, like I said, an excellent product. It, all these products they have out there, they all have different purposes. The best thing to do if you have something in mind as to what you’re looking to get out of a fuel treatment is rich in each individual bottle. Um, they all serve different purposes. Um, if you still have any questions after that and you can’t make up your mind and local parks still help you out and get you on the right track.

How to Diagnose Car Problems When It’s Not Starting

Why a vehicle doesn’t start, can be a complicated question, but in many cases, we have to start our diagnosis with some of the basics. And so there are basically two things that we look for first and at is does the vehicle have spark and does it have fuel? Those are probably the two most common reasons why of the vehicle doesn’t start. So this vehicle here, we’re going to do our preliminary checks to determine if that’s one of the reasons why it doesn’t start. So first thing we’re gonna do is we’re going to hook up a fuel pressure gauge to the Schrader valve, a test port on the fuel rail. That way when we turned the ignition on, we’ll be able to tell if the vehicle actually has fuel pop operation. Of course, that’s very important as always when dealing with gasoline. Uh, be careful not to spill the gasoline.

I’m anything hot and keep a fire extinguisher close at hand. The next thing we’re gonna do is we’re going to, we know that you know, this will prove whether or not the fuel pump works. We need to know whether or not the, uh, computer is sending signals for the vehicle to inject. So I’ve disconnected one of the wires, um, from one of the six fuel injectors on this car, I’m inserting a little test light is called annoying light. And this way when we crank it over, we should get some indication as to whether or not that signal is being sent. Lastly, we need to know if the vehicle has spark. So what we’re going to do is disconnect one of the spark plug wires from a spark plug and we’re going to install a spark tester and see whether or not it has sparked. So now what we’re going to do is we’re going to crank it over and see which one of these things that we have. So first off, we’ll just turn the key on and see what happens. All right, so you’re going to need to focus on that. Ready for that shot came up to 40 PSI. Hopefully, you got that with the movement.

Can we turn the key on? It came up to 40 PSI and at indicates that the fuel pump works, and that should be enough. You’ll pressure to actually have this start to vehicle. The next thing we’re gonna do is we’re going to crack the vehicle over and we’re going to check and see whether or not the Lloyd light blanks and that’ll give us some indication of whether we have signal coming from the computer to turn the injectors on and off. No, I like blanked. And that indicates that we’re good in a good signal from our computer and it gets, the computer’s probably conscious and so that’s a good sign.

How do Motor Starters Work?

A starter is essentially a very powerful 12-volt motor that is designed to turn over your car’s engine to allow it to start. Uh, when you turn the key on your, your ignition 12 volts goes to the solenoid on the starter motor. Um, this solenoid does two things. It allows voltage to go to the starter motor itself, which causes it to spin. And it also engages a gear on the shaft of the starter motor, which meshes with the flywheel on the engine. And so when the flywheel engages the starter motor gear, uh, it turns with the starter motor.

Now once the engine is running and you release the key, the solenoid retracts and the gear disengages from the flywheel and the engine is running some signs of a starter motor. Failing may be that the gear does not engage the flywheel, in which case you would hear a whirring sound, what the engine would not turn over if the starter motor doesn’t turn over at all. It could be a bad starter motor, but it could also be a dead battery or a bad cable or a bad ground connection. Um, the best way to test a starter motor is to hook up a connection or directly to the starter motor to bypass the cable and verify that there are no issues in the wiring harness.

Headlight Alignment Tips

Do you know for sure that your headlights are aimed properly? If they illuminate only the street right in front of your car, they’re probably too low and if other drivers are flashing their high beams at you, they’re probably too high. Here’s how to find out for yourself on a level ground park your car with the headlights facing a wall or garage door about 25 feet away. Now the highest point where the light shine on the door should be about the same or maybe a little bit lower than the height of the headlights themselves measured from the ground and it is perfectly normal for the driver’s side headlight to be a little bit lower so it doesn’t blind oncoming traffic for owners of older Honda’s Acuras in some luxury models. Check for a bubble level over each headlight. That can help set the vertical height, but if you do that, make sure the car is on a level surface to begin with. To that end, always check the height with the car loaded the way you will be driving it. Most of the time that’s because load in the trunk can change the height. If your headlights are aiming to lower high, your mechanics should be able to realign them relatively quickly using adjustment screws under the hood.

How Useful Is An Online Auto Repair Manual


Just like with almost any new gadget or appliance, each brand-new vehicle comes with a manual. It doesn’t provide the basic instructions on how to drive your vehicle-you should have already learned that in driving school. What an automobile owner’s manual provides are explanations on how to use the automobile’s different components and features, such as the windshield wipers, defroster, turn signal lights, etc. And depending on the automobile’s manufacturer, the manual may also contain tips and reminders on basic automobile maintenance (like when to replace your tires), defensive driving (appropriate use seat belt and airbag), and responsible automobile ownership.

However, don’t confuse an automobile owner’s manual with an automobile repair guide. If the first deals with the basic how-to in operating an automobile’s different systems, an automobile repair manual deals with, well, automobile repair. Like an automobile owner’s manual, a repair manual may still contain illustrations, instructions, and tips on how to use and maintain your automobile, but it’s more focused on providing comprehensive instructions in system repairs and automobile parts replacement. And if you think that automobile repair has a very wide coverage that it should be hard to put them all in a single manual, you couldn’t be more correct.

If we’re going to compile all kinds of repairs one can do in an automobile, we’d probably be able to produce literally tens of thousands of pages of automobile repair instructions. That’s why automobile repair manuals-whether in print or soft/online copy-come in different kinds. There is the generic automobile repair guide that covers basic troubleshooting, maintenance, and repair of the most commonly replaced components such as turn signals, windshield wiper inserts, and fuses. And because they’re generic, they can be referred to for repairing different vehicle makes and models.

If there are generic repair manuals, there are also vehicle-specific repair manuals. These basically have the same content as the generic manuals. But because they’re specifically made for certain vehicle makes and models, they could provide instructions on more complicated and vehicle-specific diagnoses and automobile repairs.
