i have a 78 f150 with a 400 in it and i just rebuilt the and its all back in and together but none of the electrical will work i have no power anywhere other than the positive post of my starter relay. if i put a piece of wire across the positive and "s" post then the lights come on and the starter turns over but without that wire nothing will work. i have replaced the starter relay twice and have checked my grounds.
