Hey guys yesterday i pilled the positive cable to clean as it had some corrosion on it well today i get to work and the battery light is on and it says to check the charging system i am wondering if i forgot something when i put it back together, i took off the nut at the rear of the terminal {is something supposed to go under the rear nut} and i loosened the smaller nut to the right of the terminal however to retighten it i had to put a screwdriver under it as it was just spinning, any help would be greatly appreciated, after work i will put my sct and check codes.
