What to Look for When Buying a Cable for Your Vehicle

You probably don’t give your vehicle’s cables much thought—until something goes wrong. Then, you might find yourself scrambling for the right replacement parts or specialist assistance to get everything up and running again. When it comes to identifying what makes one car cable different from another, the answer is not a lot. They all do broadly similar things and have generally the same sort of parts—insulation, conductors, and so on. The real differences are in things like design, length, quality, and functionality. This article will help you recognize what to look for when buying a cable for your vehicle – whether it’s new or you just need a replacement part.

Check the length

Cables have maximum lengths printed on them – this is due to the design and build of the components. Most car cables have a printed length of around 30 feet. It’s worth checking this length before you buy, just in case yours needs replacing – you don’t want to have to call a mechanic out for a job that could be done by someone with basic DIY skills.

Check the quality of the wires

Cables are made from two or three wires – or in some cases, one thick wire. The design and type of wire used affects the quality and lifespan of the cable as a whole. For example, a three-wire cable will be able to carry more power through it than a two-wire. Similarly, copper-coated wires are better than uncoated. Cables made with quality materials will be better at transferring power – and are more likely to stand up to wear and tear.

Check the quality of the connectors

The connectors at both ends of the cable are responsible for the connection between the cable and the rest of the vehicle. Even a high-quality cable could be let down by shoddy connectors. In general, the better the materials used in the connectors, the longer the cable will last.

Don’t forget about durability

Just because a cable has been built with high-quality materials, doesn’t mean it’ll last. If a cable isn’t built to last, it won’t. Cables that are exposed to the elements will wear out more quickly than ones that are kept in a covered area.

Other things to look for: colour and flexibility

Cable colour can tell you something about the material used. For example, yellow cables are typically made using rubber insulation, while black ones are made of oil-resistant synthetic rubber. Cable flexibility can have an impact on its lifespan too. A cable that’s too stiff may not be able to bend and flex as it’s meant to.

A final word: cables are only part of the equation

Cables are an important part of your vehicle’s overall electrical system. However, they aren’t the only thing that keeps it running. Be wary of buying cheap cables – the lifespan could be very short. Cables need to be maintained to keep working. Make sure you clean them regularly. Avoid leaving them in a hot environment where the insulation may melt or being exposed to extreme cold weather conditions where they could freeze and crack.
