RE:  Trouble shooter "logic" - starters

My daily driver quit on my recently.....battery "appears" good but nothing else is happening when I try
to start her up?

I have no manual and need to know where to start in my search for my 12V current to starter?
Do I check for 12V at solenoid (after switch)?
If 12N is there but still nothing, do you replace just solenoid or both starter & solenoid?

Thanks for info. to get me started on this new task....
