I'll look into voltages and grounds after work today. If I recall the battery and alternator are about a year old. I was thinking a ground issue for some reason.
Thanks for the link to
http://mbcluster.com/ , I hope I will not need to go that route quite yet. The fact that all my idiot lights just all stay on time seems to point to a ground or voltage issue.
I'll do a bit of investigation and post back.
