Like fluorescent lamps, HID lamps also need a device called a ballast, a compact electronic circuit that provides the high startup voltage to create the initial arc in the lamp, then regulates the current to maintain the arc at a steady brightness after that. Unfortunately, bright headlamps ...
Wire connectors Replacement ballast 1. Shut off power to the fixture. Do this by turning off power at the main circuit breaker. Once you have removed the diffuser to gain access to the bulb sockets, test with a touchless voltage detector to confirm that power has been shut off. ...
The motors are installed by attaching small sections of brass tube to the hull with epoxy, then slipping plastic wire ties through the brass and around the motors. This is a system that has proven to work very well. The bottom photo shows the running gear of the Scharnhorst, which is one...
The television tuner is the device that takes a television signal (the one coming from a cable wire, for example) and interprets it to create a video image. Like LCD monitors, these plasma displays were just monitors that display a standard video signal. To watch television on them, you ...
