Hello and welcome back to our series on automotive tools and how-to guides for the new weekend warrior auto mechanic. This is not for the professional, but for the average person looking to get their hands a little dirty on the weekends. We’ve covered a lot of tools in the past, but in today’s article I’m going to cover a short explanation on how to look at your car’s wiring. Over time, the plastic or nylon insulation that covers your car’s wiring can crack. This leads to possible electrical shorts and other general chaos.

Of all things, electrical problems affect auto mechanics much more than other problems because of how difficult it is to find and trace them. Also, intermittent shorts cause conditions where it is difficult for you to duplicate the problem to find the solution to the cause. That’s why it’s best to make sure you take a look every time you’re under its hood. Until you have become a true Jedi Master for car wiring, I suggest you ask a professional to rewire or rewire as it can turn into a real nightmare if you are not careful. Even a single improperly connected wire can cause the car to malfunction or worse, cause catastrophic damage to the car’s engine or electronic control unit.

If you decide to do it on your own, take this tip with you. Clearly mark where each wire comes from and where it goes. Also, when I’m doing this type of work, I keep a diary of the colors of the wires and how many pins the connectors had. However, I caution you once again to have a profession perform any rewiring. However, at least now you know how to stop a potential problem before it becomes a series.
