Once you’re done with checking the car battery, disable the engine so that things don’t move while you’re working. If … The voltage should read 12 volts. The most obvious symptom is a completely silent car that does not respond when you turn the ignition key. The next step, if the battery tested well, is to test the voltage at the solenoid. Have a helper turn the ignition key to "Start." Required fields are marked *. Relay vs. Solenoid. The starter motor is one piece of the starting system in your vehicle. Materials You Will Need. They provide LEDs with the specific voltage two functions so as to perform with full efficiency. Intermittent issues starting the vehicle. The start relay is located inside the same compartment with the compressor and is plugged into the back of the main device. If you have identified the type of relay with the help of the above image, then just follow one of the following methods : The first method is by using a multimeter Set the mode of multimeter to the Continuity mode, Step1: Connect the two probe of multimeter to the coil terminals( C1 & C2) as shown. These two tests are very easy. The starter relay is designed to redirect power from the battery to the starter solenoid, which then activates the starter to spin over the engine. The LED driver is also known as LED power supply. This list is updated for the year 2021 as these are the better apps ‘performance-wise’ are found […], Looking for a circuit simulator app for android phones? Step 1. Top 9 Best Scientific Calculator App Android – 2021, Top 7 Circuit Simulator App for electronics engineers in 2020, Where to buy electronic components online? Depending on the type of relay we will discuss how to test a relay using different methods. Electronics and electrical related 5000 apps for electronics engineers or hobbyists can be found easily on google play store, it could be a bit confusing to decide which android […], Where to buy electronic components online? Fortunately, you can isolate and troubleshoot each component to quickly determine which component is causing your Nissan not to start … The reading should be less than 5 Ohms. Disconnect the power to … They’re small components but make the primary circuit that supplies power to the main starter system. Before you begin with the tests, find a working battery that’s fully charged. Have a helper turn on the ignition switch while you listen to the noise the starter relay makes. How to test the relay with test light? Position the relay on the floor, counter or table so the "s" and "m" terminal are facing down. 3. Try to check if this solves the problem. A strong click from the starter relay shows its working while a series of weak click or a single weak click show its bad and needs replacement. Step 2. The current eventually pass through the starter solenoid and motor, making the engine to kick off. Part 2 of 2: Test the starter. Other pieces or parts of the starting system include the battery, battery cables, a starter relay, connecting wiring, ignition switch, Transmission Gear Position switch, Clutch Interlock switch (manual transmissions) and in some cases the engine computer. How to Test Starter Relays. Find the particular relay you want to test. Testing a starter relay is fairly simple because of its position in the engine bay. Step 3. When you turn the key to start your car, you are activating the ignition switch. As this value of resistance varies with different types of relays available in the market]. Test the battery first. Locate the two input and output terminals present on the starter solenoid. You can also check for resistance by placing the red probe of your multimeter to the ignition circuit terminal and the other to the ground terminal. Use a circuit tester to see if the current is getting to the solenoid. But, these things don’t happen when the relay is bad or damaged. I'll explain them step by step. Inspect the battery and starter terminals. From this image check the similar match relay. Another way to test for resistance by use of a wire jumper. if the buzzer ring then your Electromagnetic coil is OK. A digital multimeter; A piece of wire to act as a jumper; Wrenches and a ratchet & socket set( in case you will need to remove the starter relay, or dismantle anything else) Testing The Starter Relay You would need to inspect the leads and clean them out. If the relay still does not work, then it may have burned out. I am Thomas Yang, the product manager & engineer of T&X. General and most common faults found in starter relay are at: i) Coil: (conditions- burnt coil, broken connection), ii) Movable contact: (condition- lost its movability, carbon covered/rusty contact due to sparks), Pinout diagram with the notation: NC: Normally closed NO: Normally opened COM: Common C1/C2: Power supply to the coil, (just keep in mind that types of relay differ only on the basis of the number of terminals but the actual principle of working is same i.e principle of electromagnetism). How to test a relay without multimeter? If turn on the ignition switch, there’s a single or a series of weak clicks, you will have to test it for electrical resistance. As someone turns the key, poke the solenoid terminal on the starter or the “S" terminal of fender-mounted solenoids. Almost 2.9 – 3.0 million apps available on the Google Play Store as of now in 2020. Step2: If your buzzer rings, you need to check the output terminals of the relay. If it’s more than that, there’s a problem with electrical conductivity to the starter relay which needs to be addressed. You will easily find it near the battery and has the battery’s positive terminal wire connected to it. Like most of the switches in your vehicle, the ignition switch controls only a low-powered signal, in this case to start … How to test the relay switch? (common for all type) At first, Set the mode of multimeter to the Resistor mode. If the voltage you read is not 12V when the ignition switch is turned on, the starter relay is faulty. And, you only need a few tools. Place one probe on the lead on the ignition circuit terminal and the other on the ground lead. If the Buzzer does not ring this means that your coil is faulty. It is often referred to as the starter “S” terminal. Once you turn the key or press the starter button, it will send a signal to the starter relay, making the current flowing through the relay’s coil. Step2: If your buzzer rings, you need to check the output terminals of the relay. Place one lead of the circuit tester … Step 2: If your buzzer rings, then you have to check the output Contact Terminals of the relay (check above fig). The voltage drop should be no more than 0.2V. Keep your connections in place from the first test, and simply disconnect the back probe from the positive terminal on the battery. You do not need to lift the car or to dismount many parts. With pliers, preferably needle-nose pliers, take the connector of the wire and remove the relay. Lots of people searching now a day to buy electronic components store but very few are able to find a good one. This is a simple multimeter test. Understanding its need, 12v to 6v converter- Best 5 circuit collection, Simple calculator download in 2020 latest version, Best 4 Power Bank circuit explained using TP5086/ boost circuit, 12v to 5v converter- 4 Simple Circuits for projects, If your start relay is not working or working occasionally then consider. Here’s the list of the best scientific calculator app for android for you, if you are a student or an engineer or need to calculate large scientific calculation which is more time consuming and unnecessary to do manually. You will find the resistance of the relay coil. Starter relays do fail. First of all, identify the relay you want to test with the help of the image given below. Still, it could be a case of a failing battery that’s not sending enough current and that needs to be replaced or charged. Step 2. Fortunately, a car relay is easy to test. (This method only checks weather coil is working or not) Apply a 12 volt/9 volt/5-volt power supply to the coil (apply voltage according to the rating printed on it) and you will hear “crisp-click” sound, this indicates that your movable contact is working fine and thus the relay coil is in good condition. or (NC terminals) Connect your multimeter probe to the terminals (87a & 30), if the Buzzer sounds, means relay movable contact is fine, otherwise it is faulty.
