    Turn signal oddity

    Turn signals work fine in the garage. The left signal works fine all the time, riding included. The right signal....Is difficult to get to work, finicky, but works fine sitting in garage. Now, if I click left signal on, just to light the bulb, then go right, the right works. Any ideas??

    Check all the connections? I had some signal trouble recently and ended up replacing the turn signal relay too. Under the seat.

      I'd be cleaning out the switchblock, lube the switch and check the wires for breaks / bad solder.
      Current:
      Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha )

      Past:
      VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
      And a bunch of other crap Yamahas....

        I had the same problems until I cleaned everything up and replaced the switch inside

          Could also be a low voltage issue. Check your charging output to be sure you are get enough juice to run the turn signals. One side could have dirty wiring and contacts at the bulb fixture also, and that would require more voltage to work properly.

            Must be in the switch or related connections. Both the TSCU and the relay are oblivious to which side is being used. Only the switch determines that. Low voltage can cause issues but, more than likely, related to both sides.

            Darn, with so many daily riders it's hard to decide which one to jump on next.

              I will pull the switch apart and start there. I have recently had all signals apart, they are good. I took them apart to snug em in, bring the fronts closer to the headlight and did the same thing to the rear.

                I have had 2 bikes that the charging system was failing on and both bikes had the left turn signal act up by not blinking correctly. Replaced the stator and R&R and the problem went away. Never did have to open up the switches. Has been 25 plus years since the fixes and no problem at all with the said turn signals operation. So it can happen. Checking voltages is easier than taking the switches apart and then finding that you still have the same problem exist.
