Replacing faulty Capacitor :

After your capacitor testing has shown that you have a faulty part, the replacement procedure is simple. If you have a dual run capacitor (the capacitor has three terminals on it), then you should mark the wires and write down where they go. Then simply disconnect the wires, replace the faulty part and then reconnect the wires.

If your fan or cooler motor is moving slowly then the best way to increase ceiling fan speed is to change the capacitor.

The reason why cooler motor slow as they get older is because the capacitor loses its capacitance. This will lead to lesser torque and speed. You can change the capacitor and restore the rated speed of cooler motor. 

There are steps to change Electric Switch (with Two Wires) as below :

Turn off the power to the switch at the main circuit breaker or fuse panel. Unscrew and remove the switch plate; then use a voltage tester to make sure that the circuit is dead. Unscrew the switch from the electrical box and pull it out with the wires still attached. After removing old switch, now connect wire to new switch. Fit switch plate back into wall, turn on power back and lastly check your new switch.

Inverter

The inverter is one of the most important and most complex components in an independent energy system. To choose an inverter, you don't have to understand its inner workings, but you should know some basic functions, capabilities, and limitations. 

Their common bond is the storage battery which absorbs and releases energy in the form of direct current (DC) electricity. 

In contrast, the utility grid supplies you with alternating current (AC) electricity. AC is the standard form of electricity for anything that "plugs in" to utility power. DC flows in a single direction. AC alternates its direction many times per second. AC is used for grid service because it is more practical for long distance transmission. 

LED Bulbs

LED is small, very efficient solid bulbs. LED is basically semiconductor devices. They work when electrons fill and empty electron holes within the device. When this happens, photons are ejected. LED contains no mercury and is completely safe for the environment.

LED is substantially smaller, making it ideal for applications that require a very small light source; but due to its small size, the illumination that it can provide is far less compared to a CFL. To counteract this, it is common practice to use multiple LED bulbs, grouped together with the use of reflectors to focus the beam. 

Easy Steps for repairing VU LED TV Remote Control :

1) Open battery housing and remove the batteries : Remove the screw located in the center of the battery housing. Top and bottom shell of the remote are held together by 4 latches per side. The most fore and aft ones are located about 1cm from each end.

2) Open remote control by using a dull knife : We may have to make our way into the crack on the side/edge of the remote, Pry them open with a small flat head. We should be careful as it can make tiny scratches and we need to put some force to open it.

3) Clean the circuit board and keypad to remove any dirt and oil. Check, after cleaning, if the remote is working again; dirt could be the only problem. An old toothbrush or soft cloth can be used to clean the keypad and case. The cleaning solution for the circuit board is alcohol. Just rub the circuit board down with a cotton ball and let everything dry out.

How to repair fused Tube Light :

There are two coiled coils of coated tungsten filaments are used at both end caps on the tube light. Due to high voltage or sometime damaged choke, one filament of newly used tube light get broken inside our tube light, it can not conduct electricity inside tube light to vaporize mercury gas (or inert gas).

To repair fused tube light, the principle is very simple, we have to complete conductivity or circuit of broken filament from outside of tube light. For this, we will use copper wire outside of broken filament and wind this wire with that side of tube as shown in video.
