126 1986 300 SDL Antilock light on all the time.

[ron59b]

My 300 SDL had 250,000 miles and the antilock light stays on when operating, dash clock has stopped working, tachometer is not working, and the center console light not working. I have been told that these items could possibly be related. Could this be related to the Over Load Protection Relay? Can anyone shed some light on this for me?

I did replace my old OPR with a used one. I was told that it was in good working order, but the problem has not gone away.

Thanks,

Ron
