Test a SwitchĪre you having trouble with the lights not working, or they are flickering? The first thing that you should do is test the switch as it is usually the mother of this problem. If the tool’s meter reads OL, it means that the cable in question is broken. The tool is used to measure the resistance between the neutral wires of any cable. The digital multimeter can, in such cases, be used to tell if a power cable is broken or not.
Some of the most common uses of this advanced tool include:Īre you having trouble with your wiring? Such problems are common and are hard to hack, especially when you aren’t sure where to begin. This device can be used to do many other things. If you thought that a digital multimeter was designed to test only the battery voltage, you are wrong. The best way to deal with such trouble is by acquiring a new replacement. If the battery readings don’t go high after several attempts, it means that your battery is dead. After the load, you should repeat the testing. The slow charging should help boost the chemical reaction of the cell and hence, the right readings. If you get a much lower reading, then it’s recommended that you slow charge the battery. With such a level of charge, it means that the battery is likely to bail on you anytime soon if something isn’t done. If the multimeter shows a reading of 11.8 volts and below, it means that your battery is 25% charged or less. It’s about 75% charged, and that means that some charging is needed. What if the display shows about 12.3 volts? That figure should tell you that the battery is not fully charged. With this reading, it means that you can go ahead with the drive. When you get a voltage reading of over 12.5 volts, it means that the battery has a reasonable charge. Either way, you don’t need an expert to help you with the interpretation of the readings. However, most people don’t understand the figures that mean that your battery has charge and which one demand for a top-up. Interpreting the ReadingsĪfter the connection and stuff, you should at least be able to pick something. Once the headlights are on, you should note down the voltmeter readings at a temperature of around 26.6☌. The trick here is to provide your battery with a light load. You should turn the lights on while the multimeter cables are still attached to the battery terminals. The next step will require you to have some assistance because it involves turning on the headlight of your car. Next, you should go ahead and connect the positive terminal to the multi-meter’s red probe. The positive cable of your voltmeter is usually red. Therefore, finding a negative end shouldn’t be a problem. The multimeter’s cables are usually colored red and black.
Once the knob is at the 20 DC volts mark, the next step is to connect the negative side of the digital multimeter to the negative terminal of the battery to be tested. The first and most crucial step is to adjust the voltmeter to a 20 DC volts mark.

Without saying much, here is a guide on how to attach the multimeter to your car battery and interpret the readings.ġ. With the digital interface, the chances of collecting the wrong readings are minimized. Therefore, when it comes to testing the load on these kinds of batteries, a hydrometer can never be used.Īlso, the tool is preferred by the experts because it’s known to provide accurate readings. You must have in mind that these models don’t have the removable caps. The use of this Cen-Tech Digital multimeter is much recommended as it works well for the maintenance-free cells.
