who were some authors from 1930-1939?
the battery on the detector is going bad replace battery,the light has nothing to do with the detector,unless you have whats called a hot wired detector which works on electricity,they are supposed to have there own individual circuit.
1. Think of the chassis ground system as a separate wiring network that is completely isolated from the main circuit. It is intended to connect all the non-functional metal components togather and make them electrically common, Such as: green ground wire in the electrial plug, the metal chassis, metal control panels, motor cases, etc. but the chassis ground is not intended to participate in the operation of the main circuit. 2. No wire in the chassis ground network should ever be connected to any point in the main circuit. 3. WITH ONE VERY NOTABLE EXCEPTION: the the chassis ground is intentionally connected to the power supply neutral at 1 and only 1 point, this point is called the System Bond. It should be located as close to the power supply Neutral/Return as possible. The purpose of the chassis ground system is two fold; 1. To help prevent electrical shock, 2. To help ground spurious electrical radiation and to keep it from interfering with other parts of the main circuit. A ground loop occurs when the chassis ground system is connected to the main circuit in more than one place. It is important to maintain the System Bond as a single point connection between chassis ground and the main circuit. A ground loop will not always cause solid problems, but it can and occasionally will cause, much harder to resolve intermittent problem. It should be avoided.
