Long gone are the days of horse-driven carriages and marine vessels that were powered only by the winds and other elements of nature. Men are now dependent on automotive vehicles as their main mode of transportation. These vehicles mainly use electrical energy to get going. A car is composed of numerous electrical connections, so it is no surprise that a car can have problems because of these electrical connections. The main culprit is corrosion.
Corrosion refers to the gradual decay of an object due to the action of another element. It usually refers to the eating away of metals into smaller particles. How is corrosion produced in a car's electrical connections? It happens when there is moisture and this touches the metal parts of the electrical connections. These metal parts, because of the current passing through them, stick together and the electrical connections attract other particles. These particles could accumulate and eventually, they will be able to stop the connection between electrical wirings. Electrical resistance is heightened and as a result, some electrical parts may stop working altogether.
So how can you prevent corrosion in your car's electrical connections? First of all, you must keep the connections clean all the time, so there won't be too many particles loitering around, ready to build up at any sign of moisture. You can keep your terminals and electrical connections clean by using a wire brush.
Many car aficionados recommend the use of dielectric grease, which because of its non-conductive nature, effectively seals out moisture. To use dielectric grease, you must ascertain how much you need and buy enough for the task to be done. Have something to apply it with, like a small applicator. It's a MUST that you disconnect the electrical wiring that you will be working on. Otherwise, you might get injured. Do not work on several wirings all at the same time, so you won't get confused when you're placing them back together. Once the metal parts of the connection can be seen, apply a small amount of dielectric grease on to it, using the applicator. Apply the grease evenly on the surface of the metal part.
After an electrical connection has been cleaned, some people suggest that petroleum jelly or electrical contract grease be applied to the car's electrical terminals. Doing this will also prevent corrosion. When examining your car, take note if some electrical connections seem loose and check them out, they might be corroded.
Another thing to be wary about is battery terminal corrosion, which could lead to various problems. To prevent corrosion, check your battery every three months or so. If it needs cleaning, then make sure that you are properly protected by rubber gloves because battery corrosion is usually caused by dried acid, which is harmful to the skin.
Keep in mind that you should not tinker with the electrical connections of your car unless you are sure which is which. You might be causing more damage by trying to fix the wrong parts. Consult your car manual so you will be able to identify the electrical components properly. If you don't feel confident enough to do the tips given here yourself, then you can ask your mechanic to do the checking. Your mechanic can also determine more conclusively if there is corrosion present.
