TimberWolf Posted January 26, 2013 Author Report Share Posted January 26, 2013 I was going to run another 1/0 from the alt to the back battery but I'm prob going to get a XS batt from Mechman since I already have a D1200 for the back battery. Like they said above if your batteries are of the same composition and close on specs then you could wire them together if not then just take a run to your alt Thanks bro Link to comment Share on other sites More sharing options...
meade916 Posted January 26, 2013 Report Share Posted January 26, 2013 don't use an isolator. First of all it won't benefit you at all. Second they are actually BAD for the alternator. Think about it. The worst thing you can do to an alternator is hook up a dead battery to it and start your car. Sure, it will start the car on the 2nd battery if you drain the system battery, but once that dead battery is re-introduced into the system, it is bad news. The alternator is not going to blow up but it WILL get hot and it will have a MUCH shorter life. Try to avoid playing your system when the car is NOT running and you should be good. If you insist on playing it with the car OFF then turn the volume down to reasonable levels and cut the bass too so it doesn't tax the battery's very hard.....and don't do it for too long. With or without an isolator, you don't ever want to show your alternator a dead or very low battery. I believe a charged battery can be around a 10a load by itself but a discharged battery can show a 100a load or more while it tries to catch back up again. IMO, say no to isolators.

So I should just run straight back from the alt Link to comment Share on other sites More sharing options...
