    1985 gs 700e led blinkers

    I bought this bike from a guy and he had put led blinkers on. When we tried the blinkers the fronts would turn on but not blink and the back woudnt turn on at all. So i got a new flasher relay and now the front blink but the back ones still dont turn on at all. The bulbs arent burnt and they are all hooked up to the harness. Just wondering what to do.

    I seem to recall reading that in order to use LED turn signal bulbs, you need a TSCU (TurnSignalControlUnit) or flasher relay that is suited to LEDs. Maybe yours isn't?

      The rear has lost connection somewhere. Unplug at turn signal connector & check for current, if current on lead in wires, the problem is in the turn signal, if no current to lead in wires, you need to trace farther.

        Welcome to the GSR.

        Have you checked the blinker fluid, sometimes they get a bit low and won't work properly.

        Here's a guide https://www.youtube.com/watch?v=E6GsXhBb10k

        Good luck.

          You might try reversing the leads on the rear signals as LEDs only work with the proper polarity.

              I have power going to where my blinkers hook up to the main harness. So I dont know if it is the blinkers? The bulbs are in and they arent burnt out.

                I'd put an orig. 1056 12V bulb in it, to see if it may work. If it works, you have both pos. & neg. working proper, & the LED light is bad. Another thing may try, with the pos. connected fab a jump wire from the neg., from the signal, to a good ground on frame, ground may not be good thru wiring harness. Like TxGSrider said, many LED bulbs are directional, plugged in one way works fine, plug in opposite way won't work at all, I've been there, done that, on Tacoma dome light.

                  I tested the voltage through the ground on the harness and the ground on the frame and they were the same. I dont know if a 1056 bulb will fit in it because these have pretty small bulbs. and ive tried switching the positive and negative wires around and still nothing. 1 thing i did notice is when i took off the original relay it was a 2 prong but where it plugs into the harness had 3 prong options and i tried in 2 spots and one turned off all blinkers and one made just the front work.
