How to test your car battery?

We are battery tester manufacturer, I want to tell you how to test your car battery.

Car Battery Testing & Voltage

It's important to test your battery and electrical system regularly, not just when it's starting to show signs of weakness. Proactively testing it (or making sure your mechanic does) twice a year will help reduce your chances of failure. Most retailers offer a simple free five minute battery test. Use our Find a Retailer for a location near you to get a free battery test.

When Fully Charged, How Many Volts Should A Car Battery Have?

Fully charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don’t have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights. If they are dim, that indicates the lights are running off the battery and that little or no charge is being produced by the alternator. If the lights get brighter as you rev the engine, it means the alternator is producing some current, but may not be producing enough at idle to keep the battery properly charged. If the lights have normal brightness and don't change intensity as the engine is revved, your charging system is probably functioning normally. If you’ve been experiencing problems with your battery system and the headlight test checks out okay, you should check whether or not the battery is holding a charge, or if something on the vehicle is discharging it.

How Do You Perform A Load Test?

To pass a load test, the battery must maintain 9.6 volts at 15 seconds when tested at one-half the CCA rating and 70°F (or above). This test must be done with a true load (carbon pile) and not one of the hand-held testers that work off a conductance algorithm. The test must be run with the battery in a high state of charge. Be sure to read and follow all safety and handling instructions on the battery, this website and your battery tester. If you would like your battery tested, use our Find a Retailer for a location near you.

We provide high quality battery tester.

What are the characteristics about wiring system startup?

I work for an auto emergency tools manufacturer, today I share you that the characteristics about wiring system startup.

1. Direct control of the ignition switch starter circuit ignition switch in the startup files directly controlled suction pull starter holding coil, used as a switch to start the relay contacts.

2. Starter motor with start protection control circuit

1) When the ignition switch is in the 0 gear, circuits are disconnected.

2) When the ignition switch Ⅰ gear (not started) power line: generator excitation meter →ignition →coil indicator→ lights.

3) When the ignition switch Ⅱ stalls, in addition to turning the circuit, but also turned the starter relay circuit: battery positive ignition ----- starter relay coil Relay NC Ground contacts ----- negative battery driven starter motor.

4) engine ignition work, boot protection relay normally closed contacts disconnect, cut off the charging indicator grounding circuit, the charging light is off, the generator is working properly.

Engine ignition work, but also cut off the start relay coil grounding circuit, when the generator is working, even if the ignition switch to start the file by mistake, the starter does not mesh with the flywheel, flywheel ring gear and start to avoid broken machine, play a protective role of starter.

Ball joint service: Insights and replacement tips for vehicle applications

The “scissors” or “pivot jaw” type ball joint separator features two forged halves that share a common pivot point. A cupped-out seat engages on the opposite side of the joint from the stud and the driver side of the tool jaw engages the stud tip. As the captive threaded bolt at the opposite end of the tool is tightened, the jaws that capture the joint compress, popping the interference-fit joint out of its home.

The tip of the adjuster bolt features a ball bearing to prevent the stud from digging into the tool’s drive end as the bolt is rotated. The pivot point features two pivot positions (pop the pivot pin out, adjust for a tighter or wider jaw distance and reinsert the pin into the appropriate pivot hole).

The tool is adjustable to accommodate up to a two-inch spread for different size ball joints. This handy style joint separator can be used on various styles of ball joints as well as certain styles of outer tie rod ends.

Using compressive force as opposed to impact force allows a controlled separation, reducing the chance of damaging adjacent surfaces.

This style of tool requires no hydraulic assistance, and it’s a handy item to keep in your arsenal of suspension specialty tools.

Do you know the oil filter wrench?

An oil filter wrench is a tool for removing spin-on type oil filters. These filters are smooth, cylindrical canisters with knurling on the bottom that are difficult to grip, especially when they are oily.

One common type of wrench is shown on the right. The loop of chain is placed around the filter, and the bar is turned anticlockwise by hand until the chain wraps itself tightly around the filter. A socket wrench or adjustable spanner is then used to turn the hexagonal bar further in the same direction. This increases the tension in the chain, which bites into the soft metal casing of the oil filter which helps prevent slippage.

Another type uses a metal band that is attached at both ends to a handle. The looped band is placed around the filter and the handle is turned anticlockwise, which puts tension on the band, causing it to grip the filter.

A third common type of wrench utilizes a metal or plastic cup that is shaped much like a socket. The cup is placed on the end of the filter, which engages the knurling. A socket or wrench is then used to loosen the filter. Volkswagen Group and BMW cars require this type of wrench to remove their filters (or the lid of the filter housing, where a non-cartridge filter is used).

How clean the engine compartment?

1. Cleaning the engine compartment debris manually

Before the official clean-up, we need the engine compartment of leaves and other debris cleared.

2. Idle completely shut down for about 5 minutes after

The reason sure the car idling for 5 minutes, because after the engine idle for some time, the car will make the engine oil temperature becomes soft, thus easier to clean. But also there is a flaw, that is after the car the temperature rises, the owner at the time of cleaning can easily be burned.

3. The cleaning agent is sprayed onto the surface of the engine

Since the engine in use for some time, there is usually grease clung to it, at the time of cleaning generally requires the use of special cleaning agents. Therefore, this step is to spray the cleaning agent to the surface of the engine.

4. Sponge

After spraying the engine cleaner, car owners will use a sponge to scrub the entire engine compartment.

5. Rinse with water cannons

The final step is the use of engine washing gun to clean the engine compartment of the car. Of course, if you still worried about a short circuit in the engine compartment of electronic devices, you can use wet towel or a dry towel.

5 notes you need know when install valve

You know our company is an auto tools manufacturer, we can provide high qualty tools to meet your demand. Today, I tell you 5 notes you need know when install valve.

5. If the valve switch is used frequently lubrication at least once a month.

How To Detail Your Car's Engine?

Engine detailing is nothing more than cleaning the exterior of the engine and the engine compartment, and applying dressing to protect and beautify the engine. It's very easy to do, and requires no more than 45 minutes to an hour every couple of months.

When you are ready to remove the degreaser, hose down the entire engine compartment and surrounding surfaces with plenty of water. If you're using a high-pressure nozzle, be careful that you don't get the nozzle too close to the covered electrical connectors. Using auto detailing tools gives you better control and a more even flow than most hose attachments. Allow your engine to air dry for several minutes before using a towel to wipe down all accessible parts. Remove the plastic bags. The heat from the engine will assist in the drying process; however, do not allow the engine to air dry, as this will result in water spots. When dry, start your engine and allow it to run for a few minutes.

5 Best Auto Emergency Tools

With good fortune, you may never need to use one of these auto emergency tools in an accident situation, but that does not mean that you should not buy one.

On the contrary, it is best to make sure that you always have one of these life-saving emergency escape tools close at hand, just in case the worst does happen and you need to break out of a vehicle window following a road accident.

As well as having a hammer, many glass breakers also incorporate other survival tools, which can prove to be equally as crucial in the event of an emergency. A seat-belt cutter, for example, will enable you free yourself and others quickly. A flashlight will aid vision in the dark, or provide you with the means to signal for help.

Fatalities and injuries caused by vehicle entrapment are very often completely unnecessary. I cannot recommend these tools strongly enough. I hope that you find my list of the 5 best emergency window breakers for cars useful.

Multi-Function Safety Tool: The Swiss+Tech ST81010 BodyGard!

Handyman: Tool gifts have changed in past 100 years

Last Sunday is Father’s Day in 2016, dads who like to work around the house can expect a new power tool to help them with their to-do list. But what could dad expect back on Father's Day 1916? After all, Father's Day was first celebrated only eight years earlier in 1908.

When looking back at the types of hand tools around the homestead in 1916, we see some familiar and not so familiar ones. Back in 1916, many of the tools used by fathers revolved around farming, cutting lumber and building homes, barns and furniture.

For farming and gardening, tools like the hammers, screwdrivers, pliers, wrenches, clamps were found around most homes. Fast forward to today where the power tiller, weed whacker and hedge trimmer has taken the place of these manual garden tools. And while the wheelbarrow is still a staple in many homes today, the old version made from metal with wooden handles and a metal spoke wheel has been replaced by hard plastic or aluminum with hard rubber tires that make it easier to use – and it won't rust.

While today's handyman father may be doing some home maintenance or renovations, in 1916 chances are the father was actually building the home or making furniture from scratch. While chopping down a tree today is done with a gas-powered chain saw, in 1916 the tools of choice would have been a two man hand saw or a crosscut saw.

So if you are fortunate to celebrate this Father's Day with a grandfather or great-grandfather, ask him to tell you about the types of tools he used back in his day. While it won't be tales from 100 years ago, you will still get a good history lesson on the evolution of home improvement tools. It really never gets old. Learn all you can.

How to use multimeter?

Rectifier with a multimeter can measure AC and DC current, voltage and resistance, and other electrical parameters of the magnetic-electric instruments. Today, I will tell you the use of electrical testing tools, specialmultimeter.

1. You should be familiar with the functions of multimeter before using it, according to the object to be measured, correct selection of stalls, range and lead jack.

2. When the measured data size is unknown, first you should range switch, placed in maximum, and then switched to the large range of small-scale file at the meter pointer to at least 1/2 of the full scale.

3. Resistance measurements, in selecting an appropriate gear ratio, the two will collide lead the pointer refers to zero, such as pointer from zero position, adjust the "zero" knob so that the pointer to zero, in order to ensure accurate measurement results . If you can not zero or DRO emit low voltage alarm, should be checked.

4. When measuring the resistance of a circuit, you must cut off the power supply circuit under test, measurement can not be charged.

5. Using a multimeter measurement, pay attention to the safety of persons and instrumentation equipment, the test can not hand the metal part of the touch pen, switch gear switch does not allow charging to ensure accurate measurement to avoid electric shock and burning instruments and other accidents .

Car rainy maintenance tips

After the storm, the weather tends to be more hot and the sun is more sinister. After more rain and strong sunlight the aging of car paint and parts will be accelerating, you should do regular routine maintenance. Here I will introduce several summer rainy season car maintenance methods.

1. Cleaned

Encountered heavy rain, the car should be returned promptly for cleaning, or can lead to the gap at the side of the vehicle under the accumulation of sludge, which is moisture to hiding places, but also the most likely to lead to rust place.

2. Paint protection

Acid rain components on the car paint has a strong corrosive effect over time will cause damage to the car paint, so the rainy season, it is best to give the car to conduct a paint repair capacity. The simplest is waxing, longer and more effective closure of the glaze is tolerance. Whatever the method, gave the car wearing an invisible cloak of protection, to prevent paint fade aging, often accompanied by capacity to make beautiful car around.

3. Chassis care

The chassis is the ground and the closest site, subject to road conditions particularly serious, generally the easiest part of rust stains, even at the wheel housing may be loose perforation. Therefore, we must pay attention to clean the car chassis rust treatment, do a chassis rust treatment, rust effect can be kept for 3 months. Care must pay attention not rust finish with an alkaline cleaning solution rinse body and chassis, it will affect the rust and rust shorten the time.

4. Start ignition

Rain, owners often encounter difficult to start the engine problems, sometimes even if we manage to start up, but also weakly. Such illnesses most likely by the ignition system leakage due to moisture generated. Furthermore, it may be one to rain the weather cools, and enclosed in a hot air distribution boards is likely to condense into water droplets caused by distribution boards inside a small flood that destroys the normal ignition function.

Once because of damp caused by the ignition system misfire, engine performance degradation, it is best to use a dry paper towel or dry cloth to distribution boards and wires and other internal and external dry, then spray cans with desiccant desiccant spray in the distributor cap, battery connector, spark plugs, ignition coil and high voltage, etc., and so after a while you can start the engine up.

5. In addition to water brake

The vast majority of car brake system is a dual hydraulic brake booster vacuum pipe, worthy of attention is, to pass the braking force brake fluid is extremely absorbent. If water into the brake fluid in the braking process, the high temperature generated by friction causes the water vaporizer. The gas is compressible, the brake fluid is compressed, it will cause brake failure or even failure. Rain for a long time, the air humidity will increase, if the brake fluid before the rainy season there is a small amount of water, it would be very dangerous. Some of the more serious brake fluid absorbent vehicle, the brake fluid can see the drops of the oil cup lid. Therefore, when maintenance must check the brake fluid in order to ensure the safety of the occupants.

Our company as one of the biggest auto tools manufacturer, we provide auto detailing tools, air duster gun, engine washing gun, spray and foam gun, etc. If you have any question, please consult us at your time.
