Battery isolator installation?

Does anyone on here know how to install one. I need direction.

Sincerely,

Do you have an isolator or a relay?

I have an isolator

I don't understand this. It is currently jibberish to me. Research seems to be neccesary but do you know of a video that shows how to install one? I looked on youtube and couldn't find a video.

You have one input and two or more outputs. What is confusing?

Hooking it up is my concern

What one did you buy? Did it come with instructions or any specification sheets?

What kind of automatic isolator is this? Solenoid or Diode based isolator?

I made a wording error. I am going to be buying an isolator

Couldn't tell you. Run from alternator goes to big nut on the relay. A run from the relay to your battery goes on the other big nut. One of the small nuts is for a ground, the other is for the active signal (couldn't tell you which one is which. It will say when you buy it). For example, my active signal is through my fuse box via a fuse tap so that when I turn on my key the relay switches over and the alternator is connected to the battery. Otherwise the circuit is open.

That's a relay. What Jake posted above is how you wire it. It should also include instructions.

This solution is muhc better than just having two batteries connected without an isolator right?

And i thought the alternator wire connects direct to the starting battery of the car?

Meh. When I was talking about my relay years ago I was told it was worthless, but I already had it so I installed it anyways. The thought is so that when your car is off, and alternator is not running, the relay will stop the batteries from trying to charge each other if there is a voltage difference between the two. Even if this happens, it's not catastrophic; as long as one of your batteries doesn't have extremely low voltage.

And i thought the alternator wire connects direct to the starting battery of the car?

It does. You can either run a wire from the positive terminal on the starting battery to the positive terminal on the extra battery, or just run another wire from the alternator to the extra battery. I chose the second option.

Alright thanks man for all the help. I just need to install one so i don't have to break the bank to buy expensive batteries all the time
