LED turn signal question.

[cruz del sur]

I actually already did change to the flasher and took out the self canceling. Now, I have a question. If I remember correctly, my 70-something also had a right side turn signal switch. I like the idea of being able to turn on the switch with both hands or, even better to be able to have both signals at the same time (warning signs) anyone knows if there are right hand switches and what year they are???

Actually, Cliff has one. I have it copied in the computer, but don't have the URL.

Found it. Here it is: http://members.dslextreme.com/users/storagecliff/images/turn_signal_relay_replacement.pdf

Nice tutorial for changing out the flasher unit, but if you notice this quote from the top of page 3:

Please note that I am leaving the Blue/Black wire disconnected. This will disable the auto-cancelling feature of the turn signals.​

you will notice that this does not go along with the original question that I posted last year.​

OK, I have seen many posts about LED turn signals, and I know that I will need an electronic flasher unit to get them to flash at a somewhat correct rate, but would like to know if anybody has actually done this, and can tell me whether there is any problem keeping the self-cancelling feature.

On second thought, it really does not matter if you have changed to LED signals.
The main question revolves around the use of the electronic flasher and retaining the self-cancelling feature. .

Sounds like I am going to have to move this up my priority list due to increased recent interest.

Wow, all that position talk.....er....well....never mind.

Mine is just three solid positions--- L-C-R on my 750, and i have to push it back to center manually to cancel the signal. However on my 82 650L the three position switch is momentary left or right, meaning it returns to center after activating the signal. I PUSH the lever in and it cancals the signal. Never tried to leave it on to see if it turns itself off. I'll have to try it.

A quick test is to just push the switch to left or right with the ignition off. Turn ignition on and lights should NOT flash. If you then push it in towards the momentary position it should reset the self cancelling unit and flashing should start.

So I have very little experience with the 80 on version of the self canelling control unit but here's what I can tell you...

The turn signals operated when they wanted on my 79 850 GN and because of the price of a new controller, I built my own using a uP. The 79 version is different to the 80's on controller, but from what I've found, only in the way the 12v out of the controller is directed to the required turn signal pair. The 79 version had two relays to provide this function - one per signal pair, the 80 and later version only has one relay and uses the turn signal switch latch feature to enable the correct signal pair.

From building my own '79 version controller which has been working flawlessly for almost 18 months on my machine. I can tell you categorically the loading of the signals is nothing to do with the self cancel feature on the '79 version. If I were a betting man, my money would be on the 80 version being the same.

I concur with a lot of what's been posted here on system functionality. I can add a little to the speed sensor functionality:

The sensor in the speedo opens and closes relative to the speed being measured by the speedometer. I measured this to be a frequency of around 24Hz at 10mph. My uP based system can sense this signal and correctly calculate the current speed but I've not used that in my unit to self cancel as yet. I intend to get to that this summer and add that in.

Perhaps a further improvement would be to pulse the 12v output with the uP to directly provide the 'flash' instead of being reliant on those flasher units and their loading properties. We could throw them away for good then. Relay's don't care about loading!

Just my 0.02

OK on the 80 the loading by the signals definitely has nothing directly to do with the self cancelling unit, but the special flasher unit required to work with the cancelling unit is dependant on the load and no other off the shelf non load sensitive flasher relay can handle the self cancelling signal. If you want to run LED flashers, you need a special flasher and then the cancelling featur cannot be retained.

This is valuable information as I have never got around to measuring the frquency of the reed relay pulses. You could use your PIC to also calculate the distance travelled after a turn and the speed and monitor the brakes.

Thanks for the valuable information. We are waiting for such a design by someone who can do it and I think if you have the time it would be most welcome.

so who is gonna pick this ball up and run with it its been a few years some one must have somthing by now.....steve?

 

[Steve]

... some one must have somthing by now.....steve?

Has it really been that long?

It's still on the back burner, but still don't have time to work on it.

[old school]

just a dumb thought here but what if a guy wired both flashers in parralel that way you would have the electronic to operate the led signals and the other to operate the auto cancelling it would not matter if the tungsten bar ever moved in the old flasher .... well i guess it would so how about opening up the old flasher and remove the tungsten bar ????? who knows i am going to order a couple of flashers and play with that i dont have any setting around unless some of you do (hint hint) all i know is we cant let this one drop because i am almost sure every gsr with a auto canceller will be converting if we figure this out so what do i have to do to motivate you again steve ? i know we can call your wife and tell her that her bike would look sooooooo much nicer with leds ha ha

 

[old school]

guess it hasent been a few years i was looking at join date instead of post date but it has been close to a year... i think

 

[Beaker]

Not really much help to you guys who want to find a relay/flasher unit and maintain your ASC, but I fitted one of these M-Stop units to my 1400 when I fitted my integrated LED rear light/indicators. It has a self cancelling option which is purely based on time (20 seconds) - not too much of a hassle, especially when you weigh that minor inconvenience up against having self cancelling indicators. Did the job for me.

This is what it allowed me to fit - nice ass without the standard storks sticking out, hey?

LED Signals

LED Signals

I have LED turn signals on all of my bikes. Badlands make a Turn Signal Load Equalizer that loads the flasher unit for proper operation. Here's a link to one on Dennis Kirk: http://www.denniskirk.com/jsp/produ...re=&catId=&productId=pH50046&leafCatId=&mmyId=

It usually sells for about $26.00

 

[Steve]

i know we can call your wife and tell her that her bike would look sooooooo much nicer with leds ha ha

Actually, it would look the same.

Yep, I have been thinking of using a board full of LEDs in place of the standard bulb, but it would be in the same housing, so it won't look any different until you turn them on.

I was inspired by these lights, but not by their prices.

load equalizers

load equalizers

I found some load equalizers that are fairly cheap and claim to solve all our problems. I just ordered them with express shipping and will let you know if they work! ray:

I also ordered the badlands load equalizer for my 78gs1000 and should have it today or tomorrow. I'll let you know if that works also

 

[sponsored1]

Well i got the badlands load equalizer. My led turn signals now blink normally and the self canceling feature is working. My only problem now is the turn signals themselves are really really dim when the bike is at idle. As soon as it revs up they get bright. The battery is brand new and fully charged and i checked the grounds and all of them seem to be fine. Any ideas?

 

[Steve]

Check the voltage at the turn signal leads when they are flashing and compare that with the battery voltage.
If there is very much difference, you have a problem with your wiring. If there is not much difference, your LEDs just need more voltage to get bright.

[H.M.S.]

Hey I don't know if you figured it out yet but I just installed leds on my 83 gs750. I read up on it and I just went to Pep Boys and bought a generic electronic flasher that had the same terminals as the suzuki flasher. The turn signals work just fine. I did have to mount the flasher in a different spot cause it wasn't the same shape as the stock one. The flasher shouldn't have anything to do with the self cancelling feature. The stock ones are activated by a thermal switch that heats up by the draw of the filament bulbs. Electronic flashers work by cycling the circuit by time. Most new cars use electronic flashers so they are readily available at your local auto parts store. Hope that helps you, good luck.

All true, except that there is a wire that goes from the turn signal control unit to the stock flasher. I have not confirmed it yet, but I think that turns on power to the flasher relay. When the turn signal controller is satisfied that you have gone far enough, fast enough, it turns off the signals by removing power from the flasher relay. That was the question that I posted in the very first post of this thread.

Please let me (us) know whether your self-cancelling still works with the generic electronic flasher. I have a feeling that it doesn't.

Flasher relay

Flasher relay

I have the same problem with my modified gs1100e i have looked into different ways of fixing the blinking problem with a bright flash. The best i've seen is to go on fleabay and look at one of the flasher relays that are sold just for led blinkers. I plan on buying one soon. I have no idea as far as blinker canceling and how it works with that but i assume it will work fine. My blinkers only work at around 2k rpm or higher so my issue i believe to be a voltage based issue. I am running bulbs btw not led's.
