    dumb question about big 3...

    I have a 91 mr2 turbo. as you guy already know the engine is in the back so the 2nd step of big 3 is power wire from alt to batt... during my upgrade of big 3 I discover that there is an 16+ foot of 4 guage running from my alt to my battery already from factory. I was Planning to do big 3 with 2 guage wired but it really big to be runing throught the fire wall back to the front where the battery is...

    here is my question...

    instead of running the power from alternator back to the battery. Can I just hook my amp postive to the alternator positve.

    any reply is greatly thanx.

    What kind of glue are you guys sniffing. The alternator runs the vehicle when the engine is running, not the battery. The alternator recharges the battery when it is running. If the current demand is too high for the alternator the battery will dump in what it can. Current flows in both directions guys, it does not just go from the alternator and magically arrive at the battery through a one way gate.



    Yeah, whatever

    Do you realize what you just said. The Battery regulates the flow from the alt, SO that when you do rev the engine higher the current going from the alt stays at a constant. And you don't fry important stuff in your car.




    Don't PM me, I'm not here. Find me on SSA or ROE
    No, I won't re-upload the Big3 pictures. Don't ask.

    Explain a voltage regulator in the alternator. I was not aware that in your car, current only flowed in one direction.......... think about this as well.



    Yeah, whatever
