Analog electric motor checker - This highly portable vehicle diagnostic tool is necessary in the repair and maintenance of three-phase machines. A technician will also use this auto diagnostic tool prior to installation to make sure that circuitry is completely sound. Some of the faults that it helps in detecting include: Open circuits, Loose connections, Faulty installations, Rotor flaws, Short circuits. All the above mean that electricity is either flowing inefficiently in the system or not at all. If not detected early on and fixed, the entire machine will deteriorate at a faster rate meaning that more expensive repairs and replacements will be needed.
When doing auto electrical repair, the first vehicle component your should acquire knowledge about is the car battery. Even though the battery only store 12 volts, it is the electrical source of the entire vehicle. You will not be able to start your engine without the battery. In addition the auto battery helps to operate all the electrical accessories installed on your motorcar. An auto battery should last 3-5 years in average climates. Extreme hot or cold climates however, will reduce this to only 2-3 years.
An auto battery is built up of six cells, each containing stacked positive and negative lead plates. These are divided and separated by insulators and immersed in an electrolyte, a liquid blend of sulfuric acid and water. However, some batteries, use a gel instead of the electrolyte. This is considered to be safer and because you do not have to refill it with electrolyte, it has been labelled "maintenance-free". Each cell generates or more correctly put, stores 2.1 volts for a total of 12.6 volts.
A dirty or clogged engine air filter is more likely to reduce acceleration than fuel economy, according to tests conducted by the EPA. Because filters get dirty gradually over time, you might not notice a small but steady loss of performance until your car is accelerating like a turtle. But if you haven’t changed the filter in a couple of years (or sooner in areas that have a lot of soot in the air), that could be part of the problem.
