;DHi guys I have just mounted four led blinker assy's on my SR500 and guess what all blinkers come on at once don't blink just glow , so the question is how do I fix this, I guess it's down to load on the blinker can so how do I calculate the load needed and do I mount a resistor at the blinker can or at each blinker assy? Thanks T.C.

Maybe check the de-structions, a lot of LED indicators require a relay to operate (not all kits though) but a few do?  |

Hallo,
there are special led indicator relais available as aftersaleparts
best regards sjef

Hi guys
I have bought a led blinker relay that is supposed to work with leds or globe blinkers . sorry just the same al four blinkers just glow softly whichever way I push the blinker switch any more ideas I dont want to put in load resistors if possible . T.C.

Mate,
There is something more wrong than just the wrong load. There should never be more than two blinkers and the light in the tacho in the circuit, so if you have all 4 of them on you must have wired them wrong or something has gone wrong with the handle bar switch.

A lot of the bikes have a bimetal strip (thats the bit that ticks) , its in series with your 2 lamps so when you put leds into the circuit the load changes hence the bimetal doesnt get hot enough to tickety click . So you've got to find an electronic relay or you've got to load up the one you've got . Measure the resistance of your old lamp with a multimeter times it by 2 , the resistor will have to be about 10 watt (wire wound porcelian) across each led . I think it'll work ! Dave .

To clarify what Dave said - you have to put the resistor across each lamp circuit, not *each LED* (since there's usually a bunch of them). And, since front and rear are on the same circuit for each side, you really just need one resistor per side.

Yeah thats what I did mean , I'm a sparks by trade & explaining things isnt one of my finer points . I was more concerned about describing how the circuit works to give an insite why resistors need to be incorporated into the circuit .(It may be possible to use zenner diodes) If there is any electronic wizz's on the site how about a comment ? Cheers Dave.

Cheers Dave. Forget all that and buy an electronic blinker relay. Then you can put on any type of indicators. |

You said it exactly Dave - the bimetal flasher needs a signal lamp to draw a certain amount of current to make it heat up and switch. Put on LED signal which will have much lower current and... no flashee. So you parallel the LED signal with a resistor to draw the extra current that the LED isn't. (This of course negates any power savings you might have been after.)
Palle's suggestion to buy an electronic blinker may work, but for two issues. 1) Yamaha blinker relays have an input for the automatic cancel, generic ones don't; and 2) sometimes electric blinkers act very flakey as they seem to get spurious input from somewhere, too high impedance input or poor grounds or what have you. This is a known problem on XS650s which are closely related to our bikes.
One option (going on heresay, haven't tried it myself) may be what's called a "wide load" blinker relay. Has nothing to do with your girlfriend... it means the blinker can handle a wide range of load currents.

yes, but why do all four blinkers glow at once?

Why did the Chinese build the great wall? Coz of the rabbits ( theres alot of rabbits in China!) You could be right too there may be a fault at the handlebar switch just for the hell of it . Dave.

Hi guys I have solved my blinker problems finally !!!! bought a led solid blinker relay from the states "Custom Dynamics " if I remember and they recommended to either take out blinker bulb in tacho or fit diodes both sides of bulb as the buld acts as a current feed to both sides of blinker circuit , it works just fine but I dont have a warning light in tacho and the automatic blinker cut out gizmo never worked anyway so I am just fine now ...TC

Well done , problem solvered . Its good to have a solution so we can all learn by . Cheers Dave.
