Q: Electrical Short on 1991 Mercedes-Benz 300SL

Every once in awhile, when I am driving and turn on the blinkers, the dash acts like I just turned the key off and then right back on....The car runs fine during this...It's crazy... Any thoughts? This sometimes happens when I turn on the lights as well... Thanks for your time..

Check the regulator under the plastic cover in the upper left corner of the engine compartment. There is a red thing with two fuses in it. Check those fuses and replace if broken. I just had the same problem and that fixed it
I looked under the hood and there is only the fuse box with all the fuses. I didn't see a red box...
Thanks!! Had a blown fuse in the red box and took care of that issue and some others as well!
I have the same problem, have not found the box with the two fuses in it, where can I find it, left side meaning drives side near the dash?
I had the same problem and just had a fuse blown in the red box and turned my ABS light off, my MPG needle started moving again, and car runs better. Thanks
My 91 300 sl does the exact same thing. every once in a while, when putting on the blinkers, all of the idiot lights on the dash briefly light up..Was told it's a short in the bliker stalk. in 2 years, never caused any problems..
