Greetings Forum Members,

I posted a request for help with a starter problem on my 1985 280sl.
I could hear the starter solenoid rather noisily engage but the starter didn't turn over.
I suspected a bad starter and replaced it only to experience a quiter solenoid with the same no turning over of the starter.
I need help diagnoising this problem.
Where is the relay that controls the starter and how do I check it?
Also how do I check the ignition switch function?
These are the new suspected culprits.

Thanks,

Knarf
