I dont want to make a new thread to dedicate to something minor but, this weekend I did 1 of the big 3 upgrades. The ground to chassis with 0 guage. I couldnt find a good place on the block to comfortably put another ground from the battery there, and the alternator to battery is already 1/0, there would be literally no point to replace that unless it was coroded. Since I was at it though I put on new terminals (mainly to hold the fat wire for the ground), and voila! no flickering as long as I am moving in gear. Idle it still flickers, which I expected. So I think Im going to buy a 1 farad cap and all should be good, idle or otherwise.
