A battery isolator typically is used in situations where multiple batteries are required, and its primary purpose is to ensure that the failure of a single battery will not incapacitate an entire electrical system.

Some sort of battery isolator is required if the alternator is going to be used to charge more than one battery.Ī battery isolator is a one-way electrical device that allows an electrical current to flow in one direction but not the other. These batteries are typically deep cycle batteries that prefer to be partially discharged and recharged on a regular basis. The batteries used to provide power operation of DC and AC appliances in a work truck, recreational vehicle, or boat are called the house batteries. If this battery is drained down because the car won't start or the lights were left on, the battery life decreases rapidly and will probably remain dead the next time it is drained down. Automotive type batteries do not like to be discharged to a low level. This battery relies on the alternator to keep it charged up for the next cranking cycle. The vehicle (chassis) battery is typically an automotive type of battery that provides high cranking amps to start the engine. Work trucks, boats, recreational vehicles, long haul trucks and fleet vehicles all have a battery isolator if the alternator is being used to charge both the house and vehicle batteries. Then use another piece of the wire to ground the negative cable of the car's battery to the frame.What type of battery isolator should be installed? 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.
