A diode isolator is positioned between your alternator and your batteries, and the built-in diodes let your alternator charge those batteries while keeping them both isolated from each other. Each have their own advantages and disadvantages. You’ll have to choose between diode isolators or relay isolators. Systems with more robust batteries should take advantage of equally robust supporting equipment. Though you can find more powerful kits for niche scenarios, most people will be well-suited by almost any properly constructed battery isolator. For the better battery isolators on the market, these typically range between 120A and 150A. You want isolators rated to carry the amount of voltage and amperage you expect to draw. Different batteries have different needs. Isolation aside, different vehicles have different batteries. Seemingly simple features, like start isolation, can ensure that your sensitive electronics won’t be subjected to the kind of sags in voltage that may occur when engine cranking happens. Expanding beyond two batteries isn’t only prohibitively expensive, it’s totally unnecessary in most circumstances. But for someone seeking a simple two battery solution, what you’re looking for is a dual battery isolator. If you’re planning on running a giant battery bank, filled with hundreds or thousands of batteries, then you’d need a pretty impressive isolator. Luckily, it’s not that tough to choose an effective battery isolator. You don’t want your battery isolator to cause problems with your vehicle’s electrical systems, or with the devices connected to whatever local grid you’re working on. Perhaps more importantly, ending up with the wrong detector could be more trouble than its worth. Then use another piece of the wire to ground the negative cable of the car's battery to the frame.Choosing the Right 12V DC Dual Battery Isolator Crimp on 2 electrical connectors that will attach BAT to A. Then, cut a piece of the 14 gauge wire so that it fits between the alternators BAT terminal end and the end that is marked with an A on the battery isolator. Be sure that they are secure and tight when you are hooking them up. This is where all of the wires from the BAT terminal that you just connected are going to go. Look for the terminal on the isolator that is labeled 1. All of these wires will need to be disconnected. Next, check for the wires that are attached to the BAT terminal, which will be located on your alternator. Then, take the negative cable from your actual car battery and remove it. Keep in mind during this step that you have to disconnect the negative cable before you attach the positive terminal to anything so that you do not get shocked. Once you have hooked up the isolator you can do the actual wiring. Again, hold it on tight so that you can secure it completely flush with the frame. Carefully drill around the isolator attaching it to the frame with the sheet metal screws. You may want to have another person help you with this step to hold down the isolator securely as you drill. Be sure before you do any installation or securing that you can close the hood with no problem and that all other parts work without disruption. This is typically done in the engine compartment and needs to be hooked up to the actual metal part of the vehicle.

Now that you know whats going on under the hood, you can install the isolator.

Then, once the car is ready to be worked on, you will want to check out the manual just to familiarize yourself with everything that is going on so you know where to look. You do not want to be working in it and then burn yourself or cause any electrical damage.
Then, allow the car to cool completely for about 20 minutes or so, especially if you were just out driving. This is an extremely important step so that you do not do any damage to the car and more importantly, to yourself. Begin by making sure that the car is turned off.
