This is often done for several reasons, including:
* Noise Reduction: Routing the ground through a specific component can help isolate electrical noise from affecting other parts of the system. This is especially useful for sensitive electronic components like audio systems.
* Current Sharing: Distributing ground current across multiple paths can reduce voltage drop and improve overall system efficiency.
* Signal Return Path: In some cases, GTO wiring helps to create a defined return path for signals, enhancing signal integrity.
However, GTO wiring is generally discouraged in modern automotive applications because it can complicate troubleshooting and introduce unforeseen problems:
* Difficult Troubleshooting: Tracing ground paths becomes significantly more complex, making fault finding more difficult.
* Increased Resistance: Adding extra wire lengths and connection points can increase overall ground resistance, potentially leading to voltage drops and malfunction.
* Ground Loops: Improper GTO wiring can create ground loops, causing electrical noise and interference.
While the concept might appear efficient in specific, well-defined scenarios, the potential drawbacks typically outweigh the benefits in the vast majority of automotive electrical systems. A well-designed system with a clean, properly grounded chassis is generally preferred.
