Well yesterday I was installing my efan controller. I simply wired the red positive into the starter solenoid and when I went home she was clicking. So I simply jump-started into second and thought it was a dead battery. Well this morning she won't start. I took off the battery terminals and cleaned the posts and terminals with some sandpaper, and even poured some Coke into the showing wires that are crimped. I know the battery has juice, but she just wont start, just an annoying clicking sound.
I'm having trouble if it is the starter solenoid or the battery connections?
