What Exactly Does a Battery Isolator Do?

A battery isolator is an electrical device that divides direct current (DC) into multiple branches and only allows current in one direction in each branch.

The primary benefit of such an arrangement is the ability to simultaneously charge more than one battery from a single power source (e.g., an alternator) without connecting the battery terminals together in parallel.

This is beneficial because a weak or dead battery will drain the charge from a strong battery if both are connected directly together

Correct Fuses

We have included the Projecta recommended 150AMP ANS fuse to use with the wiring kit. BE CAUTIOUS of other sellers that supply cheaper and incorrect fuse types, this will potentially cause damage to the DCDC charger and batteries.

Wire Gauging

In this kit there will be 5M of RED 6B&S (6AWG) and 1M of 6B&S Black (6AWG). This wire gauge should be perfect for engine mounting of the battery. If you wish to mount your second battery in the boot/tub/trailer, the thickness of the wire will need to be increased. We have created a second kit for this option: AMS40055

Protect your wires!

Many other wiring kits do not include corrugated split sleeve tubing for your wires. Professionals will always protect wires with corrugated split sleeve tubing to prevent damage from impact and heat.

Tools for the job and extra parts:

We stock a range of 12V wiring tools for the job. We did not want to add these to our kits because we know many of you may already own them. However, we also recommend that you have the following tools for the job ahead:

Also below will be the part numbers if you wish to order any extra split sleeve tubing, lugs and wire.
