    Riding home yesterday my left signal came on and wouldn't shut off, even with the key out. I opened the fuse box an smelled burning plastic, pulled up the signal relay and it was hot as balls and a small hole was beginning to melt open. I disconnected it and signal went off.

    I bought the bike used, question is, is the signal relay in the photo below of the one that malfunctioned the incorrect one to have in the box?

    I called the local dealer and they gave me the part # of 61317679867, which doesn't match the one I had.


    Also should say the right signal has not worked since I got the bike and am now thinking this relay was possibly the problem?

    Anyone have similar problems? Are these relays super specific to each bike model or is there crossover?

    And finally, does anyone have a spare relay they'd sell for a fraction of the $135 BMW wants for a new one?

    Thanks!

    Matt,

    I believe your relay is in fact a solid state controller. I would open it up and have a look. If I'm right, you may be able to identify the burned component and make repairs.

    Doesn't really look repairable? I found a used replacement on ebay for $20, same specs, different part #. Hopefully it works.

    Would like some insight as to why it happened if anyone knows, so I can prevent future problems.
    Thanks

    I would check the wiring and circuits for shorts.

    Also, I would check those components that are scorched and replace them. See if that works.

    the bulb housings are where I would start looking for a short or maybe a bulb inserted incorrectly

    Hey mouthfulloflake & Matteapolis,

    I have been searching around for any issues like mine. I just picked up a 95 GS1100 this week. I'll be trouble shooting a no turn directional or 4 way flashers.

    I'm going to try the flasher relay, but I'm looking for a fuse box label or a pic of it. My Clymer Book does not depict it and the decal is missing from the fuse panel cover under the seat.

    Any help or pointed links to GS110 info is appreciated.


    Thanks

    It is my first BMW, previous XR650L and KLR

    this will help you find the turn signal relay

    Thank you both, I'll check out the minder and mouthflake, that helps greatly!

    I'm encouraged by "Hank" and his 400k GS. I just picked up this GS1100 with 75,000 on her. I'll post some pics soon.

    Looking forward to TAG-O-RAMA once again.

    Drone,

    I ordered the SM, tomorrow I have some time and I'll be checking the lights and harness for shorts. I should have the SM Relay by next weekend.

    Until then its hand and arms signals. :clap

    Best.

    Hello!
    I recently had this problem. All repaired simply - the replacement of the control transistor D16N05 (in the original) or IRFR4105
    Also, just in case, they have been replaced by n-p-n transistors BC847F

    changed control both sides - circled

    I do not know what the cost in your countries - in Russia, this repair cost $ 2

    Well, last time I was in your beautiful city visiting friends at the university, I should have brought my relay for you to repair. That relay (its not really a relay is it, more of a solid state controller) is ridiculously expensive and looks overdesigned for the purpose.

    Next time I will be glad to help))
    Absolutely agree! I'm going to install additional fuses for each side. In one general I do not hope more than

    I did not know my bike came to me with a Kisan installed

    until it failed to blink one day

    I removed it, called the company asked about a replacement yadda

    sent them photos via email
    they said that unit went out of production 12 years prior

    so I ponied up the $129 or whatever for the updated model
    and it has been flawless since 2009

    I figure most faults for the kisan or stock unit stem from bulb and socket issues or wiring issues

    as stated above if each side signal circuit was fused I predict any flasher would last a lifetime

    For me it was a big surprise that the transistor burned but did not fuse, which should protect the transistor.
    It is logical to assume that the individual fuse will solve the problem on each side.

    +1, I did the same on my RT and up to this day it still works.
    I still have a couple of these transistors, if anyone needs them PM me and I can ship them ASAP, in case they are hard to find in your area.
