Tobias Posted August 6, 2015 Report Share Posted August 6, 2015 Hi, I have 3 optima yt batteries at the moment to power my amplifier. These 3 batteries is in the trunk of my car and then i also have a stock battery under the hood and i can only fit one alternator. Now to the problem, how exactly do i make my alternator charge the batteries in the trunk without having my bad stock battery in the circuit, i heard that it is not a good idea to to have a bad battery connected to my batterybank. Please help me, it would mean alot. Sorry if my english is bad. Thanks in advance, Tobias Link to comment Share on other sites More sharing options...
Miguels Posted August 6, 2015 Report Share Posted August 6, 2015 I have wired my stock battery with the rear and had no issues. If you are worried use an isolator my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

jbeez Posted August 8, 2015 Report Share Posted August 8, 2015 I use a 500A stinger relay that comes on with ignition, so the lower voltage front battery isn't possibly draining the rear AGM batts while the car is off. The front batt rests around 12.7v and the rear batts rest around 13.4v. When the car is running the Alt is pushing out a higher voltage than either battery so there's no issues there hope that helps Link to comment Share on other sites More sharing options...
