Oven elements or heat elements are the heating coils on the top and bottom of your electric oven. They heat up and glow when current flows through them, and the oven turns on. However, these heating coils may get damaged over time. Damaged coils do not convert electric current into heat or they may do…

hFE is a unit of measurement for determining the amount of current gain (or amplification) that a transistor can produce. In other words, hFE is the ratio between an input current and the resulting output current, and it can be used to help determine how suitable a particular transistor might be for a circuit or…

The manifold absolute pressure (MAP) sensor detects air pressure in the intake manifold and allows the vehicle to change the air/fuel ratio. When a MAP sensor malfunction, it can impair engine performance or cause the check engine light to illuminate. It uses a vacuum to monitor the pressure in the intake manifold. The higher the…

An ABS (anti-lock brake sensor) is a tachometer that measures the rapidity of a wheel. It then passes the calculated rotational speed to the Engine Control Module (ECM). The ABS is also known as the wheel speed or brake sensor. Every car wheel has its rotational speed; the ABS sensor notes these speed rates. On…

Are you trying to troubleshoot why your power windows aren’t working and think you may be dealing with a broken power window switch? Most of us face this issue from time to time with an older vehicle. Whether you have an automatic or manual switching mechanism, you’ll have to deal with this as soon as…

A digital multimeter is one of the most useful tools you can use to troubleshoot electronics. The continuity setting on a multimeter allows you to check if there is a complete path for electricity to flow between two points. What is the Multimeter Continuity Setting? The Multimeter Continuity Setting is used to test if a…

Some applications and a few recreational vehicles such as wheelchairs, golf buggies, and motorcycles, need 6V batteries to function properly. Learning how to read the voltage is necessary to maintain your battery. You can measure your battery voltage with a multimeter and your 6v battery if charged fully should display a reading between 6.3 and…

The fuel pump is a critical component for a car’s entire operation. When the fuel pump fails, it implies the engine’s fuel supply is insufficient or there is none. This will be true if the engine fails to start or stall. We’ve outlined some steps below to help you diagnose this issue with a multimeter.…

Single-phase motors are the most prevalent type of fan motor. Other fan motors, such as dual-phase and capacitor start motors, are designed for industrial use and are widespread in factories and warehouses. But they become faulty at some point. Today we’re going to help you test these with a guide that will walk you through…

The knock sensor is a critical component in the running of your vehicle. It is responsible for detecting engine detonation or knocking. It is critical to the effective operation of your car since detonation can ruin the engine. As such, we recommend you check your knock sensor periodically to ensure it’s working correctly. If your…
