while i'm not going to read through all 3 pgs of posts, i will say that caps can help. Those that think they don't just don't know how /why to use them. Caps can discharge and recharge at a rate that no battery can do which is why in most cases it solves the dimming issues of head lights. Doesn't matter if you have a 100 ampere or a 300 ampere alt and 1+ batteries, the simple truth is that caps can still do things that batteries simply can't, discharging and charging at a fast rate is one of them.
