Title: Turn Signal Flasher Whack
Post by: The Mighty Gryphon on December 30, 2019, 10:07:36 PM
The Flasher module on a recently acquired '88 K100RS SE has whack with the right turn signals.


Operation of the left turn signals is correct, the left handlebar switch turns them on and the cancel switch on the right cancels them.


The hazard flasher switch works normally as well.


The problem is that the right handlebar switch turns on both right and left turn signals, and the cancel switch cancels them.


I have replaced the module with one from another bike and the signals all work properly.  When I take the faulty module to another bike the same problem happens on that bike.


As far as I can troubleshoot, the relays and the relay drivers are working properly, beyond that, I can't seem to figure out what is going on because of those 10 pin strips on the circuit board.  I have purcased a replacement, but at the price of these things, I would really like to fix it and put it in my spares stash.


Anybody seen this problem and fixed it?
