Flasher Unit Modification for fast blinking turn signals

[Corkus]

...This is a listing of information others have worked out and posted on lots of different web pages. Please let me know if there are any errors in what I have posted. I'll edit out the errors. THX...

The problem: Turn signals flash too fast. (This mod may also fix turn signals that flash once and stop or new LED turn signals that flash don’t flash.)

The short version of the mod:


If your flasher unit looks like this photo then cut one PC board trace and you are done. The necessary cut is in the next photo.

The long version:

I was kindly directed to ADVrider.com for this solution by Pelican user sirius815. ADV user Poolside originally posted the solution. It took me several hours of reading threads and looking at my bike to understand the mod because I have lowly garage skills and I am slow.

There are possibly 2 or more part numbers for flasher units like mine:
My flasher part number is 61.31-2 306 979
Flasher Unit part number 61.31-2 305 700 (One ADV user worked the mod with this P/N but used the older powerboxer.de procedure. From what I can tell it will probably also accept the mod cutting the PCB Trace.)

It seems that the flasher unit is programmed to blink at a fast rate when a bulb goes out anywhere in the system. Cutting the PC Board trace sets the flasher unit to blink 1x/second no matter the load. It should work for LED turn signals. My turn signal problem was a fast flash but I was installing new dual filament non-LED turn signals. I still got the fast flashing and this mod fixed the flash rate.

Here are the most important threads.

1. The thread of the newer easier solution posted by ADVRider user Poolside
2. Google Translation of a German site powerboxer.de showing an older complicated solution that was superseded by the ADV solution.

Location of the relay unit on my 2001 R11S


To remove the relay from the bike:
Rremove the L fairing panel
Remove the cover of the wiring unit housing the relay unit
Wiggle the relay upwards to expose the bottom latch of the relay
Flip the latch as in the photo

To open relay module two triangular tabs must be undone. Slide something over the tabs like this. See next photo also. This photo edited from powerboxer.de site


Here are the tabs. Getting this cover off was not a delicate operation for me.


powerboxer.de shows an old obsolete solution for the kind of relay I have.


powerboxer.de also shows another kind of relay and another kind of solution but it is not clear what the exact solution is here or which kind of relay this is.


Poolside's solution is easy and better than the powerboxer.de solution. Photo of my relay PC board trace to cut. This trace is SMALL! It is about as wide as one of the ridges on the side of a quarter!


This looks like the easiest and roomiest place to cut to me. I used a $4 scalpel style hobby exacto knife. Worked great.
