79 450SL starting problem

I'm working on a 79 450SL. It has an intermittent starting problem. Sometimes it starts then sometimes when you turn the key nothing. If you bang on the starter then it starts again. So I replaced the starter of course and.....same problem! I'm suspecting the ignition switch but if there's a relay in the starting system (not sure if there is?) then I would look at that too. Or maybe a bad positive battery cable?
Any and all replies appreciated!

The same thing happened to my 75 280C. I tightened the battery connections and it worked. My battery isn't really the right size, so I think it wiggles and loosens the connection.
