Connecting A Battery Isolator

By Amanda Leer

The following article shows how to connect a battery isolator. The isolator is installed when the car needs a second battery. This will be required by cars that have bigger stereos. Since more power is needed second battery is added with the help of an isolator.

The hood is popped. New battery is placed on the second battery tray on the driver's side of the vehicle. It is secured using 3/8 inch ratchet and socket. Using drill the battery isolator is mounted on the fender well. Then the screws and the bracket that comes with the battery isolator are self-tapped . a length of four gauge battery cable run from the positive terminal of the first battery to the terminal on the battery isolator on the right hand side. The end of each side of the wire is stripped about half inch from the end and a terminal on to each end is crimped using a terminal crimper. The positive terminal from the first battery is connected to the terminal using a 3/8 inch ratchet and socket.

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.

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.

The wire strippers are used to strip inch off the other end of the 18 gauge wire. A ring terminal is crimped on to the end of the wire using the wire crimpers. the wire is connected to the ignition terminal on the battery isolator using a 3/8 inch ratchet and socket.

A 18 gauge wire run from the ground terminal on the battery isolator to the ground source on the frame. a wire is bolted to the frame on the passenger side. A ring terminal is crimped on both sides of the wire using wire crimpers and it is bolted to the ground point and the battery isolator using a 3/8 inch ratchet and socket.

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.

Thus the article helps us to learn how to connect a battery isolator. - 21393
