I have a 1990 560 sel, I have replaced the tumbler assembly two days ago. Now I go to start the car later today and nothing. The key buzzs when door open, but no starter engagement. No regular dash lites with key rotated to start postition.

Bad ignition switch maybe?

Does anyone have a picture or dissambly instructions there willing to share? I have a hanes manual but no ignition switch info in my manual.

I see many posts but nothing for a 1990 560 sle on ignition.
