Need HELP! 91 SL
As I am driving my car and I use the turn signals, ALL of the warning lights on the dash light up and the radio cuts off for a second. At first, it only happened once and a while, but now it happens on a regular basis. Now, it looks like the problem has progressed...some times the car completely cuts off when I hit the brakes...It happened last night, and I could not get the car re-started for about a min...Thanks in advance for any advise

I saw something like this about three times in the past. The lights would flash just as you hit the turn signal. I replaced the clusters for the repair. I actually still have two in my toolbox I used as testers. The w140 and w129 were interchangable. I don't remember an issue with the radio though.
I am not sure about your running issue.

The problem with the dash lights may be a faulty capacitor on the instrument cluster circuit board. It is easy to replace, and the procedure has been successfully done by me and many others. See this thread: http://www.benzworld.org/forums/r129...question.html?

I have learned.....
I have learned, from experience, that when I have a problem with the electrical system in the car to replace the fuses first. They may not look bad but the original fuses were aluminum which reacted with the copper connections to cause corroding. You can now find copper replacement fuses at some auto stores. Good luck!
