Turn signal gone whacky

[embe560sl]

re; 1989 MB 560SL
I have just found out that when i put my turn signals on it turns onthe emergency lights instead.I checked the emergency light switch and that works independently, okay...what is going on here, anyone ? Thank you

id say your indicator relay is bad , Id check there first

Thank you for your suggestion, but could I impose on you to find out where this is located...if you know of course.

The electrical system guide in the on line manual has a component location section but to answer the question it is behind the instrument cluster.

follow the ticking when you put on your flashers

Thank you rowdie. I am very curious about the 'electrical system guide in the on line manual' you mention. I've never heard of this before. How could I access it myself?

Yes, the quiet clicking sound is audible from around there.....why does MB make any re & re so darn difficult ???? Thanks for responding.

The ticking is so quiet, it was very difficult to zero in on the exact location...I thought it must be around there somewhere? Thank you for your response it is much appreciated.

Wow rowdie, thank you very much for 'guiding me' to this fantastic site. I can see i will be spending many many hrs now sifting through all the informative pages trying to understand the workings of this complicated (to me) machine, instead of bothering forum members. I cannot thank you enough.

The easiest 1st step is adding an additional ground from the gauge cluster to the chassis.

Something whacky. - Mercedes-Benz Forum

Thank you nobby, it's worth a try but failing that, must I assume it's the flasher relay itself that has gone kaput?

Maybe.

But MY first step would be an additional ground.

Fixes 99% of gauge cluster electrical issues.

Thank you Nobby, does that include the flasher relay too ?...or is that a separate issue?

One step at a time.

Troubleshooting 101: Do the easiest and cheapest fix available.

IF it's not the ground....then move on to the next step.

[meltedpanda]

could also be as simple as a bad or failing or wrong bulb in a socket. A bad ground at the socket ect ect... one step at a time

bulbs OK?
ground OK?
Extra Ground, any help?
relay changed ?
short somewhere?
