How To Set Up 2 Batteries?????
i was thinking...my lights are diming.... and i have 2 bateries anyway....... so im gonna hook 2 up im thinking ill use a acid battery for starting and my inside lights.....lights and all that and my Lightning audio deep cycle battery for my system..... I would judt run one but the wiers to my battery are wierd........... how would i do this... I was thinking of ruiing my 2 guage wire to the back like it is not and hooking it up to my alt on top of the connection thats already there then just using the same ground as my system sound ok?..... then i was gonna run another 2 guage wire to my distribution block................ were would i need fuses? would i need afuse going from the alt to the back battery or can i just put my circut breaker between my back battery and my amp?
the alternator (DOES) power the car when its running, not the batt
if you need proof that the alt runs the car when its on, just disconnect the battery when the car is running and it will continue to run. the alternator works the car and charges the batt at the same time.
think of it this way, the battery is to the alternator as the capacitor is to the battery.
