And when I electrically connect everything here, there are a few more wires to deal with under the wire nuts… but all LED light tubes will now be powered (via standard house AC – no ballasts) from one side. Use wire nuts to connect the socket wires. I have a desk lamp which, sometimes when I start it, causes my computer monitor that is connected to the same outlet to turn off and reset, so I disassembled the lamp to see what could cause this to happen. In any case, once you identify the hot wire, the neutral will be on the same side. If your fluorescent fixture is not working properly, use a multimeter, also called a volt ohm meter, to check the fixture's voltage to determine if the problem is the ballast or another component. Install the new ballast and secure it with the old mounting screws. Less advanced in their design than electronic models, some magnetic ballasts can’t function without the aid of a starter. Without a Ballast also the light won’t start as it provides the higher voltage to the light to start. The ballast (sometimes called control gear) is a small device wired to the light’s circuitry which restricts the amount of electrical current travelling through it. You need to cut these wires close to the ballast; these are input wires because they send power to the fixture. Three-prong grounding plug. A wiring diagram is a streamlined standard pictorial representation of an electric circuit. What is the ballast in a fluorescent light? The common wire(s) connect to all of the lampholders on the other side of the tubes. And once more – good to go! The new screw-in fluorescent light bulbs (CFL or compact fluorescent lights) have a built-in ballast in their base that works to start the bulb when you turn on the light. What’s the difference between switch start and high frequency control gear? "Follow the colore-coded wiring diagram" was the recommendation, yet after connecting all like colors on the new ballast to the fixture, all I got was a delayed, dim light at the base of each fluorescent bulb. Changing the wiring on a fluorescent light fixture from rapid start to instant start, involves changing the wiring from series to parallel. Branded ballasts can last for a long time so if you change one, you probably won’t need to change it again for 10 years or more. These rely on the principles of electromagnetism, in that when an electrical current travels through a wire, it naturally generates a magnetic force around itself. The two yellow wires on a 4 lamp ballast are connected together inside the ballast. Separate starters are only found in older control gear, so if a fixture is less than 15 years old it probably won’t have a starter.
