    Battery Isolator and Wiring

    Ok so I'm going to install a second battery in my car. I know i need to get a battery isolator but how do I know what size to get? And how exactly would I go about wiring it? Thanks

    Re: Battery Isolator and Wiring

    Depending on the amperage of your alt and the amps your amplifiers will be sucking. The best and easiest way to go is just get matching batts and replace your facotry with another one. You can even get name brand kinetiks for what the price of some good Stinger isolators cost (130ish). However if you are set on getting an isolator you need to run a wire from alt to isolator and 2 wires from seperate posts to your batts.. thats it.. Hope this helps

    Ya.. if yopu have same batetries you dont need an isolator... You just need an isolator if you have a bank of audio batteries then a lead acid factory battery... Then they would need to be charged seperate.. if Your batts are the same you can just run 2 wires from alt to each or just jump from front batt to back batt... you dont need an isolator

    Re: Battery Isolator and Wiring

    It wouldn't be a Bad Idea to have a Battery Relay or Solenoid [Same Thing],for *Key-Off Listening*,correct?
    At least,he'd only be using the Audio System Battery *With Out* draining Main Battery/.A battery Relay or Solenoid
    as I previously mentioned is *Not Expensive* as you may think/.Honestly.With a Isolator,IIRC,You have[Suppose] to
    get one to match your Alternator Amperage,say like 100/125/150/Amp Etc. I personally would get an Relay/Solenoid
    and have the best of both.
    When it's time to fire up your car,you'll have *Not Drained the Main Battery*.And as,you start your car,the Solenoid opens
    up the Contacts[Inside] the unit,so your Alternator will charge *Both Batteries*.
    I'm doing that w/my Stang Install.I've checked w/people in the Industry over the years,and they have recommended that
    to me.Good Luck,which ever way you go w/your Battery choice & charging.It's just *MOPO and what was Recommended
    to me*.Take Care
    Regards/
    Raymond
    **PS**
    An Isolator and Solenoid-Relay are two different animals.
    They work the same,but,ther Isolator,IIRC,does take a small
    drain from the Batteries,or something like that.The others
    do not do draw any current at all.
    ***************************************
    Maybe someone w/more Electronic experience can chime in
    to explain the differences in that/.
