SSplaytoy Posted August 8, 2005 Report Share Posted August 8, 2005 I was told to get an "isolator" so that my alternator would charge both batteries. I don"t know what that is nor how to hook it up...........hence I need a lil help thanks Link to comment Share on other sites More sharing options...
dcairns Posted August 10, 2005 Report Share Posted August 10, 2005 An isolator allows your alternator to charge the auxiliary battery when the engine is running, but not allow the auxiliary battery to drain you regular battery when the engine is off. Not that I recommend JC Whitney as the ideal place to get such things, but they have a handy catalog to show you what one looks like. BATTERY ISOLATER - 90 AMP Link to comment Share on other sites More sharing options...
SSplaytoy Posted August 11, 2005 Author Report Share Posted August 11, 2005 Thanks for the info. I saw a 200 amp one. I was hoping someone could post a pic of their setup. Link to comment Share on other sites More sharing options...
fast4popper Posted August 11, 2005 Report Share Posted August 11, 2005 Thanks for the info. I saw a 200 amp one. I was hoping someone could post a pic of their setup. <{POST_SNAPBACK}> An Isolator will give you a .7 volt drop across the terminals, NOT good. I would recommend a relay set up, I carry a 200 amp relay that I use in my car that works great, they are about 40 bucks. they will handel 200 amps continuous and there is no voltage drop across the thing. just as easy to wire up too. I do have a question for you. why do you think that you need 2 batteries? just something I ask all people that want to run 2 or more. maybe I can shed some light on the subject once I get your answer.

04CHASE Posted August 11, 2005 Report Share Posted August 11, 2005 i had a two battery set up on my old tahoe. (3000 + watts) I ran dual yellow top optima and they would always be at 12 volts which i could never understand. I finally wired the batterys in parrallel.Never had a problem again.

SSplaytoy Posted August 11, 2005 Author Report Share Posted August 11, 2005 Im going to run 2 batteries because I am tired of all my power almost shutting off with bass. Even without it, if I roll my windows up there is a significant drop in power. Therefore I want to run two batteries and a high output alternator. Thanks for the relay idea too. And I will wire them in parallel. Link to comment Share on other sites More sharing options...

d_a_n_payne Posted August 16, 2005 Report Share Posted August 16, 2005 I have mine wired in parallel with no relays or isolator. My battery ran down once but now the new battery is doing fine. How long does it take to run it down? Link to comment Share on other sites More sharing options...
