Starter Installtion

OK...I'm going to display my frustration for all to see. I had to pull my starter to install the positive cable. Now I can't seem to get the darn thing to go back in. it stops about 1/4" from going all the way in. I have wriggled, tapped, pushed, pulled, twisted, turned, and cursed prolifically. Still, it will not budge any further. What in the world am I doing wrong? Open to any suggestions!
