F150 headlights kill engine

After reading many posts i just wanted to share mine 86 f150 302 FI 4x4, the engine would crank and run but if you pulled the headlights on it quit like you turned the key off. After trying multiple tests it turned out that just a little corrosion between the positve post and the terminal was causing it, the terminals were clean and showed no signs of corrosion outside but just simply cleanimg the post and inside the cable end solved all.
