Does the black or red wire go on the inside of a cart?

Answered by Edward Huber

When it comes to installing a cartridge, it’s important to know which wire goes where. The black wire is typically the positive lead, while the white wire is the negative lead. In terms of placement, the black wire fits snugly into the small hole in the bottom of the cartridge, while the red wire rests lightly on the outside metal threading.

Let’s delve a bit deeper into why this is the case. The black wire, or positive lead, carries the current from the power source to the cartridge. It is important for this wire to be securely connected to ensure a stable and reliable electrical connection. The small hole in the bottom of the cartridge is designed to accommodate the black wire, allowing it to fit tightly and securely.

On the other hand, the red wire, or negative lead, is responsible for completing the electrical circuit. It is connected to the outside metal threading of the cartridge, which serves as the ground or return path for the current. The red wire does not need to be tightly secured like the black wire since its purpose is to establish a connection to the metal threading rather than the internal components of the cartridge.

It’s worth noting that the color coding of wires may vary depending on the manufacturer or specific application. In some cases, the positive wire may be red and the negative wire may be black. It’s always a good idea to consult the instruction manual or documentation provided by the manufacturer to ensure proper wire placement.

When installing a cartridge, the black wire, typically the positive lead, goes inside the small hole in the bottom of the cartridge, while the red wire, usually the negative lead, rests on the outside metal threading. Following these guidelines will help ensure a secure and proper electrical connection for your cartridge.
