Turn signal cancelation unit...

Postby RSIRR » Sat Aug 03, 2013 11:49 am



Question; I have an '83 GL1100 std. I have narrowed my turn signal issue, non working, to the cancelation unit. Honda no longer makes this unit, and dealers in my area don't handle any. Other than manual canceling, what other issues, if any, will occur by my removing the unit and 'sealing off' the connector?

Thanks
Rick

I've done that on my 1500. I had to connect two wires together to get the indicators to work but other than that no problems. It'll do until a replacement comes along.

My speedometer cable quit working,it came out of wheel hub.Later i notice that turn signal cancelation had quit.Plug cable back into hub and turn signal cancelation started working.

The same thing happened to my 83 1100 interstate as bdukes bike. When the speedo cable snapped, the turn signals stop auto cancelling. When I replaced the cable..... they were cancelling properly again.
Most motorcycle problems are caused by the nut that connects the handlebars to the saddle :)

Thats interesting....sounds like the signal cancellation needs input from the speedo to work. On my 83 1100, the signals will blink and after a few seconds will cancel the signal even before I make the turn. I have to keep turning the signal back on a few times until I actually make the turn. But come to a stop light and the turn signal will keep flashing and I dont have to keep turning it on. Anyone know what might be the issue with mine?

The unit actually cancels the turn signal from 3 variables...
Time from activation...usually 25 seconds or so IF still moving in a straight line.
A few seconds after the front wheel angle sensor is turned AND there are pulses received by the spedo.
A number of pulses from the spedo after the stop that is above 25 mph.

I have found the canceler system either works well or is flaky...The only external inputs that really affect it is the pulses from the spedo...easily tested....and the angle sensor...also easily tested.

If both inputs are OK,the unit can be replaced...but another unit may or may not be better...remember it too is aging components...

You could unhook the spedo pulse wire.This would help in the self cancel problem.

VirgilMobile......OK, there are 3 variables that will cause the unit to cancel the flashing turn signal. The first you say is Time of Activation which is about 25 seconds. I rule this one out since it cancels in about 4 seconds.

The second is the front wheel angle sensor detects the bike tilting thru the curve. This could be my problem.....maybe the sensor is mounted slightly crooked and if it has a mercury switch in it, then the mercury would be making contact even when driving straight. Where is this angle sensor mounted?

The third are speed pulses after the stop which exceed 25 mph. I will have to test the bike from a stop with my signal on and see if it cancels after 25 mph is obtained. Im thinking that this cancellation is working ok.

Do you have a diagram showing where the angle sensor and the speedo pulses are located?

Would be nice to have a flasher that stays on until I finish the turn.

Good details.Thank you.The angle sensor is just like a volume control not a switch.Its mounted at the bottom of the steering head with 2 bolts and the 3 wires feed up through the steering head.
Measurements are easy.Use a Analog meter to see best.One wire is ground,another is near 5 volts Dc with the key on.The 3rd wire should vary from around 4.5 volts to 0.5 volts SMOOTHLY as the front end is turned from full left to right.
I did have one that started jumping around at the midrange area.
This sent false signals to the cancler unit and tripped it off.
You could unplug it to test if its the cause.
You could also unhook the pulse wire from the spedo to eliminate that part of its function.
The only thing left to trigger it off then would be the internal timer.
Unplug the angle sensor first and re-test

Virgil......Man, you know these bikes like the back of your hand......incredible. I will have to crawl down and under and peer up into the steering head and see what I can come up with. I just found this pic of the cancel switch......so now I know what to look for. So, looks like the steering will kinda "dial" this switch left or right as you turn the handlebars.

That's it.you may have to pull some slack wire at the top to get the connectors where you can reach them.
