A battery disconnect is a safety device that allows you to quickly and easily disconnect the battery from the rest of the vehicle’s electrical system. This can be useful in a variety of situations, such as when you are working on the vehicle’s electrical system, or if the vehicle is involved in an accident.
Installing a battery disconnect is a relatively simple process that can be completed in a few minutes. The first step is to identify the negative battery terminal. This is typically the black terminal, and it will be marked with a negative sign (-). Once you have identified the negative terminal, loosen the nut that is holding the cable in place. Be careful not to remove the nut completely, as you do not want the cable to come loose.
