The power required for your car stereo is dependent on the size of the car stereo. When you listen to stereo when the car is switched off then the battery will lose its power and it becomes difficult to start. To avoid this situation we can add a second battery but doing this is not as easy as we say it. For this we need a battery isolator that allows the charging of the battery while the car is running and this also separates the two battery. But how to connect a battery isolator is the real problem. This could be easily solved by doing the steps given below.
First of to do this we require a few tools and that includes a battery, a blue ring terminals, a battery isolator, a self tapping screw, needle nosed pliers, wire crimpers, a 12 volt test light , wire cutter finally a few wire strippers and a terminal crimping tool. These tools help us finish the job in a neat and a lot quicker.

The first step involves opening the hood of the car. Then place the extra battery in the place provided for it. To secure its position a 3/8 ratchet and socket is used.
In the next step with the help of drill the battery isolator is mounted to the fender. For more secure connection use the brackets and self tapping screws that comes along with the battery isolator. A 4 gauge battery cable is used to connect the two batteries. It joins the positive terminal of the battery to the right side of the battery isolator. In the same way we have to connect a wire from the positive terminal of the first battery to the battery isolator. This is done using a 3/8 ratchet and socket.
In the next step a 18 gauge wire s section is run from the battery s ignition terminal to the steering column through a grommet . A 18 gauge wire is connected to the ignition wire with the help of blue scotchlok connector and a needle nosed pliers is used to crimp it tightly.
In the other end of the 18 gauge wire ¼ inch is stripped of and using a wire crimper the ring terminal is attached to it. Now this is connected to the battery isolator s ignition terminal with the help of a 3/8 ratchet and socket. Now the 18 gauge wire is connected to ground by connecting it to the ground source in the frame.
A wire fixed on the frame near to the passenger is a good ground point. Both the ends of the wires are fixed with a ring terminal by using a wire crimper and then it is connected to the ground
using a 3/8 ratchet and socket. A four gauge wire is run from the second battery s negative terminal to the ground. By doing all these the second battery can be made to charge.
A difficult question how to connect a battery isolator can be answered very easily by following these simple steps.
