Ground wire diagram 12v system. It is clear that the grounding of the vehicles electrical system is every bit as important as the routing of power to the components. Its heavier because it has to carry more amperage. This is a video response to a question asked by a viewer of the diyoneforall channel. Less volts means more amperage.

How to wire a 12 volt electrical system in an rv. Oversize the wire if the voltage drop is critical. Normally on most boats with 12v dc systems that are more complex than yours the engine block or block of the outboard is the ground. But when there is no engine then a ground buss usually becomes the ground and all negative conductors are connected to the ground buss.

Im not asking about anything to do with the 120 volt part of the system just the 12 volt side of it and im asking because the ground wires used by most automotive manufacturers and others are way to small in most cases and need to be upgraded for electrical systems to operate properly. For more information on marine 12 volt basics read electrical resistance on boats. As early as. Second figure out if you have a positive or negative ground.

Oversize the wire if the voltage drop is critical. When translating the diagram to installation consider the easiest and most practicable ways to route the wires to keep them. Dc passes in one direction from the battery and through an appliance to ground each circuit must start at a fused connection to the coach battery and end at ground. Changing to 12v cuts the amperage load approximately in half.

Subwoofer wiring wizard easy to understand diagrams of one to four speakers with a variety of single and dual voice coils.
