Copy and open this link in new tab so we can work off same diagram
Page 2 you can see ground stud on end of starter that does not go into flywheel.
The positive or battery positive terminal goes to top stud on starter solenoid same page.
Do you understand this?

Okay make sure battery power and grounds cables go to the correct starter post,,positive cable goes to top solenoid and ground goes to back of starter,,now you should have one small wire 5/16" eyelet connection goes to S terminal of starter solenoid right next to battery positive cable post,,,The S terminal and mark is molded into the starter solenoid,,,next use you ohm meter or visually see were the other cables goes for ground cables,,you should have one that goes to engine from starter ground post,,, and one from frame to starter negative post.Besides the ground cable coming fro batteries.
After you get this all hooked up how many wires do you have left and what sizes are they?
Questions or problems let me know I'm happy to assist.
