1984 300D


When car is hot and we attempt a start we can hear a faint "click"-not the solid CLUNK of the solenoid.


However jumping at the starter box (passenger side of, near battery-large bolt to small bolt) the starter does engage and car starts.


We replaced the starter, neutral safety switch, Battery clamps and cleaned the "starter box" bolts, cleaned all connections at starter.


Any other thoughts are appreciated.
