With the abundant electronic devices installed in vehicles, the one starter battery may not be Sufficiently to arm the load. You can prolong the go of your vehicle's starter battery by adding a moment battery that can ability one or added of the electronic devices. The moment battery can simply be mounted inside the vehicle itself, on the other hand it needs to be connected to the alternator to direct it from draining.
Instructions
Connect the longer wire to your second battery's positive terminal using the same procedure as with the other terminals. Connect that battery terminal to the electrical connector of the device it will power (stereo, subwoofer, etc.). This can involve several possible methods like crimping or screwing the wire to a connector terminal.7. The Timber is a more select mark, expressly whether you're using it to faculty something in the Timber affection a subwoofer.
2. Mount a battery tray in the chosen domicile, using a tray that fits the moment battery's amount. Screw the tray into the surface (conforming the floor of the Timber), then drill a gap nearby to route the cables over. Compose firm you don't hit any other components passion the fuel receptacle when drilling and screwing.
3. Unsnap both cables from the starter battery to close off the motorcar's function, disconnecting the denying cable antecedent. Disconnect the wire that connects the alternator to the starter battery (this wire is object of the automobile's complete battery cable) by unbolting it or cutting it off at the alternator limitation.
4. Install a battery isolator (a switch box for the batteries) into the vehicle. Strip elsewhere cut of the insulation from the disconnected alternator wire with a crimping object and connect the bare lead to one of the isolator's side terminals by loosening the terminal and retightening it with the wire lead under it.
5. Connect the alternator to the isolator's central terminal (usually labeled "A") using an extra wire. Mount one bare lead of the wire under the isolator terminal and then bolt the other lead to the alternator. Connect the isolator's third terminal to another longer wire that will route all the way along the chassis to the second battery in the trunk.
6.1. Pick a stop inside the motorcar to mount the moment battery. While the engine compartment is oftentimes the beginning control, this repeatedly requires modifying the compartment to construct space for it.
Secure the wires to the chassis by bolting or screwing wire clamps to the chassis. Make sure you have a clear path along the chassis where the wires and clamps won't be in the way of any lines, manifolds or other components. An exact clear path will vary depending on the vehicle.
8. Reconnect the two car battery cables to the starter battery, starting with the positive cable. Ground the second battery by fastening a wire for the negative terminal to a metal ground like the chassis with a screw.
