As depicted in the first diagram, one of the black wires originates from item 104 and the other from item KA1? Is it still configured that way? Do you have a key/legend that indicates which component is which, for example KA1. 104, etc? Is #25 the blue wire or an item to where the blue wire goes? Whatever #104 is, make sure that ground wire has a very good ground on each end. Which item is the starter?
