How To Change The Voltage On A Century 115/230 Volt Electric Motor
The advantage of multi voltage motors is that they allow you to easily switch their operating voltage to adjust the motor's operations. Changing these operating voltages is as simple as switching a few wires around on the terminal plate, by following the diagram inside the terminal box's cover.

How To Test AC Motors
AC motors are fairly basic devices that consist of one or more run windings and one or more start windings. They only have two moving parts, the rotor and the start switch, which means that they are pretty easy to test and fix when you notice something is going wrong with the device.

A Buzzing Noise In Your Recessed Lighting
A buzzing sound coming from a recessed lighting fixture may be a harmless annoyance, or it might warn of a much more dangerous problem. With fluorescent fixtures, the buzzing sound is usually benign. With recessed incandescent, high intensity discharge and light-emitting diode fixtures, however, the buzzing sound can indicate potential fire hazards, such as loose electrical connections and defective light sockets.

How To Wire An End-Of-Run GFCI Receptacle
Ground fault circuit interrupter (GFCI) receptacles are designed to prevent electrical shocks by automatically shutting off power to the receptacle if the device detects an imbalance in the current.

How To Repair A Broken Printed Circuit Board
Printed circuit boards (PCBs) have revolutionized the electronics industry, but they lack the strength of the old hardwired, steel-chassis devices, so it's important to handle them carefully. Although it's sometimes possible to repair a broken PCB, it can be an extremely frustrating process.

How To Check A Thermostat With An Ohm Meter
There are many different types of thermostats, but they all work the same way. A bimetallic element (made by fusing two different metals together) inside responds to a change in temperature by bending as the metals expand at different rates when the element is heated or cooled.

How To Tell If A Dimmer Switch Is Burned Out
Dimmer switches have come a long way since 1961, when Joel Spira invented the first electronic dimmer switch. Modern dimmer switches can save energy and light bulbs, but they are damaged more easily than the auto-transformers and rheostats that had been used to dim lights before Spira's invention.

How To Cap Off Electrical Hot Wire
Capping off electrical wires is necessary to safely remove a device from a circuit. A wire capable of being made hot by turning on a circuit breaker or replacing a fuse needs to be capped off if not connected to a load or some electrical device. An energized wire is a shock hazard to a person making contact with it.

How To Step Down DC Voltage Without A Transformer
Transformers, which are often used to step-down voltage, work with AC (alternating current) voltages, not DC (direct current) voltages. To step down a DC voltage we need to use some other method to accomplish this task.
