Isolation testing may also be conducted between one or more electrical circuits of the same subsystem. [1] The test often reveals problems that occurred during assembly, such as defective components, improper component placement, and insulator defects that may cause inadvertent shorting or grounding to chassis, in turn, compromising electrical ...
A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments ...
Floating grounds can be dangerous if they are caused by failure to properly ground equipment that was designed to require grounding because the chassis can be at a very different potential from that of any nearby organisms, who then get an electric shock upon touching it. Live chassis TVs, also known as hot chassis, where the set's ground is ...
A technique used in recording studios is to interconnect all the metal chassis with heavy conductors like copper strips, then connect to the building ground wire system at one point; this is referred to as star grounding or single-point grounding. However, in home systems, multiple components are usually grounded through their 3-wire power ...
For ALDL connections, pin 9 is the data stream, pins 4 and 5 are ground, and pin 16 is the battery voltage. An OBD 1.5 compatible scan tool is required to read codes generated by OBD 1.5. Additional vehicle-specific diagnostic and control circuits are also available on this connector.
4. Blank Checks. Keeping blank checks in your wallet is like handing out free passes to your bank account. Only carry what you need, and treat those checks like a wad of cash — because, really ...
Fox is set to broadcast the Cowboys' Thanksgiving game at 4:30 p.m. ET. Dallas has hosted games on the holiday since 1966 and has customarily played after the Lions' early afternoon game.
An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.
