Bringing this back up again now that I've had a go with LED blinkers. Unsuccessfully.
I ended up going with indicators from
Lightech, and I bought a set of resistors from Rizoma to maintain the proper current draw (the Rizoma's are pre-wired with connectors that fit the stock 790 Duke wiring harness).
I installed as instructed. I did the rear pair first, and then gave them a test. With the rear LEDs and resistors installed in back and the stock incandescents still in front, the indicators all flashed correctly, but I got the "indicator warning" on the dash. I continued on and installed the LEDs and resistors in front, as well. Now when I try the indicators, they only light up solid; no flashing. (Though, I no longer get a warning on the dash.)
I'm a bit stumped at this point, as I'm seeing conflicting information in different places. Does the 790 Duke not have a flasher relay as mentioned in post #3 above? Or is it possible that Euro spec bikes don't have a flasher relay (because they come stock with LEDs), and US spec bikes like mine
do have flasher relays (because they come stock with incandescents)? If that's the case, is it possible the resistors still aren't providing enough current draw to mimic the stock incandescents? (Is that what solid, non-blinking indicators mean?)
I really have no idea when it comes to electronics. Any help would be
much appreciated. In particular, if anyone out there has experience putting LED indicators on a US-spec bike.
