Yesterday installed bosch platinum plus 4 plugs.
Car started and idled ok for 2-3 minutes.
I turned it off to do some other work and now
it will not engage starter.

I have since read all the negative posts re: platinum
plugs and want to know " Is there a relay or sensor
in this 500 sl that would sense a high current draw
by the ignition system and shut starter circuit down"?

I have been having intermittent starter switch problems
recently and am worried my choice of plugs blew something
else up?

Thanks

Probably a coincidence but I'd get rid of the plugs anyway.
