ok,
i still want to do this , but i still couldnt find if the alternator comes on instantly when extra power is draw,or the power will come from the battery and the alternator will kick in later to top off the loss
i have a battery gauge in my car ,and it shows less voltage instantly when i add extra load, and comes back up instantly when the load is reduced,
the only question is if this is battery itself,or the alternator, or a combination of both?
