Level Up Your Electrical Repair Skills
1. Test the Wires
One of the best ways to level up your electrical repair skills is to learn how to use advanced techniques. These techniques can help you trace wires from different places in your home or car, test if a particular wire is broken, and much more.
To test a wire, you will need a multimeter and a needle. Using the multimeter, set it to continuity mode (or Ohms mode if it does not have a continuity option).
You will also need a needle to poke along the wire until you identify a point where the needle touches. This point will be the point where the wire is broken and where you should fix it.
Getting the right needle for this method is crucial and you should make sure that it’s sturdy enough to penetrate the insulation of the wire. If it’s not, you will have trouble seeing or touching the points where the needle goes inside.
After identifying the point where you should fix the wire, you will need to poke the wire with a needle until you see the needle going through the metal string that is inside. This will allow you to get a reading from the needle and a reading from the multimeter.
Next, you will need to place the black probe of your multimeter on a different wire ending from the original one that you placed on the needle to check for continuity. You should hear a beep or a reading of “0” from the multimeter when you do this.
This process is called tracing and you should know that it isn’t a very easy procedure. You have to refer to a blueprint or a plan of your home’s wiring and identify where all the wires are expected to end.
2. Test the Switches
A switch is a mechanical device that controls an electrical circuit by opening and closing the flow of current. It is important to test switches regularly to ensure that they are working properly.
A good place to start is with a simple light switch. People use these thousands of times each year, so it is natural that they eventually wear out or break.
If you suspect a switch is bad, you can try to fix it yourself or call a professional electrician. You can also use a multimeter to test the switch for continuity.
First, you will need to determine which wires go into which terminals on the switch. You can do this by removing the cover plate and examining the switch wires.
You can also use a non-contact voltage tester to test the switch for power before you touch any of its wire connections. When you find the power wires, plug one lead into the negative socket and the other into the positive. If the meter detects any voltage (lights up or buzzes), it should be connected to a good switch and is not faulty.
Repeat this process for each of the switch’s terminals. Then, flip the switch on and off.
If you notice that the switch doesn’t have any continuity, it is most likely faulty. You can replace it with a new one.
3. Test the Circuits
When it comes to electrical repair, it’s crucial to be able to test the circuits and conductors that you work with. This can help you avoid potential problems in the future and give you the knowledge you need to identify faults quickly and efficiently.
You can do this by using a multimeter or a circuit tester. A multimeter can be used to test the breaker’s resistance, while a circuit tester can help you trace the wires of a fixture or determine whether a switch is working properly.
Regardless of which device you use, be sure to test the circuit before you touch it. This helps prevent electrocution and fire.
To test a circuit, you need access to its screw terminals or, if the device has wire leads, to the ends of the wires. You can also use a probe-type tester to trace the route of a wire or determine whether a switch is working.
A noncontact voltage tester is an inexpensive and simple tool that can help you identify the source of a problem in the electrical system. Simply touch the sensor tip of the tester to each of the circuit wires and if it lights up, you know that the circuit still has power.
While testing the conductors, it’s important to remember that temperature and contact can significantly affect your readings. This can make it hard to identify a problem when your measurements are inaccurate.
If you want to take your electrical troubleshooting skills to the next level, consider taking a course like Advanced Electrical Repair Training. This two-day course will teach you the most advanced techniques in electrical repair and give you hands-on experience with many components commonly found throughout a variety of facilities.
4. Test the Relays
Relays are an important part of your vehicle’s electrical system. They can control things like headlights, air conditioners, and even taillights. If one of these relays goes bad, your vehicle could become unusable.
There are several ways to test the relays in your vehicle. Some are simple, while others are more involved.
First, you’ll need to identify the relay that needs testing. This is usually a component located under the dash or in the engine bay depending on the circuit it controls. You can find this information in your service manual or by looking at the wiring diagram in your car’s owner’s manual.
Once you’ve found the relay, use your multimeter or ohmmeter to check its operation. Start by touching the leads across each of the electromagnet coil pins and measuring resistance. Anywhere from 50-120 ohms is fine, but out of range means the coil’s winding isn’t good and that it’s time for a new relay.
Next, connect the positive and negative terminals of a 9-12V battery to each relay’s electromagnet coil pins. If you hear an audible click as the relay energizes, it’s working correctly.
If you don’t hear a click, the relay isn’t working. This is typically a sign that the relay’s electromagnetic coil is open and damaged, or that it’s been rewired incorrectly.
Finally, if the relay is normally-open, you can perform a continuity test with your multimeter by connecting one probe to the NC (non-contact) and the other to the common (common) terminal. If you read continuity, the relay is working and you can move on to more advanced tests.
5. Test the Motors
Whether you’re performing scheduled maintenance or troubleshooting an unexpected motor failure, testing is essential. It can save you time and money by catching minor issues before they become major problems.
The first step in testing a motor is to verify that it’s operating at the correct voltage level. This is crucial to the health of the circuit, and it can also protect the motor from damage.
A digital multimeter is a good choice for checking this, as it can measure current (amps) and voltage. Some models are equipped with additional features for testing diodes, capacitors and other equipment.
Next, use an ohmmeter to test the conductors of each winding individually. These ohm readings should be within the designated values on your motor nameplate.
If any of the wires give infinite readings, that’s a sign that the cables are bad and you should call a technician to replace them.
You should also check the earth continuity and resistance of each wire. This can be done by connecting the motor to its power source and using a multimeter to measure the resistance between the body of the motor and the ground.
This test is useful for identifying winding faults, which can cause excess current to flow through the motor and overheat the electrical system. It can also lead to shorts between conductors, which cause the insulation to break down and create heating at the fault, which eventually leads to failure.
