Cars fitted with bigger stereo needs an alternative power source as they can’t rely entirely on the single battery to which they are connected. If we have an habit of listening to music when the car ignition is off the consequence will directly lead to complete drain of the primary battery source which results in problem with starting engine, the battery won’t have sufficient energy to crank the engine. This problem can be encountered by using a secondary battery source coupled with the primary source, the secondary battery can’t be directly linked with the primary battery we need a battery isolator to establish the connection .While doing so question like HOW TO CONNECT A BATTERY ISOLATOR erupts in our mind it is very easy if all the instructions are followed in this manual.

Battery isolator is a device that instructs the alternator to charge the secondary battery and also protect the primary battery from being drained. Battery isolator can be of different type but the most efficient and cheapest of them is solenoid type isolator where the isolator connection is achieved when the engine is on, off when the engine is off .The instructions on how to connect a battery isolator follows.

Open the front hood and place the secondary battery in its corresponding tray using a 3/8 inch socket and ratchet. Make sure the battery is properly in position and should not be kept tilted. Using a driller mount the battery isolator then connect the terminal of battery isolator to the positive terminal of the battery using a battery cable. The wire connecting the battery and isolator are stripped and held in position using the 3/8 inch ratchet and socket.

Now the positive terminal of the secondary battery is connected to the other terminal of the isolator the wires are held in position using the socket and ratchet.

Take a lengthy wire connecting the ignition terminal of the isolator and run it down to the car interior near the steering column, test the ignition terminal with the 12 v test bulb, the light should turn on when the engine is on and should be in off state when the engine is off to ensure the connection is established.

After the connections is checked strip the one end of the lengthy wire using a wire stripper and clamp it with a ring type crimper and fix it to the battery isolator’s ignition terminal using the socket and ratchet. For grounding run a wire from the ground terminal of the isolator the the ground point on the frame and bolt the wires to ensure a tight connection.

The negative terminal of the secondary battery is connected to the ground point on the frame using a gauge wire and is bolted on the either end to ensure connections, now the secondary battery will start charging only when the engine is on.

It is easy to couple the secondary battery with the primary battery using this manual on HOW TO CONNECT A BATTERY ISOLATOR where it eliminates the need for supervision.

For accomplishing this the car’s engine compartment is to be fitted with a specially designed plug. The wires are held in place by the small clamps and by using this and sheet metal screws one can install it to the frame of the car. Holes are drilled to fix these.

The next step involves the closing of tubing up by the zip ties. It is placed in a position about two to three feet below the flexible cable tubing.
