Calling all canceler experts....

OK I know what the issue is, I am wondering why. My signals would not work one cool morning last week but worked fine later so I could not debug. Happened again this morning so I checked the fuse the unplugged the canceler and the lights work great.

Obviously the canceler is going out on me. Having read all the earlier discussion on the function of the canceler I know it has a diode and a couple of resistors. Both can be effected by heat and cold but it seems odd it would have this effect. I would suspect not canceling before causing failure to work.

I have also had the strange effect of the signals turning on by themselves as I ride. I suspected a worn wire someplace but now I'm wondering if the canceler can do that too.

 

I would suspect the turn signal switch may be failing. Take it apart and clean the contacts first. The switch is exposed to the elements on the handlebars and can get a bit coroded after 20+ years.

Did Artie ever get his oil leak fixed?

 

Not yet on the oil leak getting the last part this week we think. There is an oil splasher for the primary chain that has an o ring - that is the latest suspect.

Switches were replaced last year by PO because the signals "worked when they felt like it". Signals were dead this morning but rock solid once I unplugged the canceler.

I'm gonna ride with it unplugged a while and see what happens. I don't rely on it anyway. I have an old habit of manual canceling from my previous bikes.

 

No harm in running with the self canceler disconnected. You might want to tear into it and see what all you can find in terms of burned components. You might get lucky and have a cracked diode or solder joint.

 

I have one that flashes and one that don't only one flasher right?

 

yup one relay and 1 canceler. Does the side not flashing just have 1 light on all the time? Usually that is a loose ground or blown bulb.

 

Haven't checked yet as it just started doing this.

 

I posted a description of the self-canceller operation here: http://www.xjbikes.com/Forums/viewtopic ... t=105.html

I would agree that the turn signal switch or the connector and wiring between it and the canceller are possible culprits - there are two sets of swtiches in the turn signal switch; if the momentary's not working correcly, the canceller won't be reset.

 

Cool I missed that one - I have not been following the LED threads. I was under the impression the hand switch was momentary.

So based on your description I can see how my signals would self start. All it takes is my having turned the signal on and so the switch is set, The canceler cancels the signal and down the road the canceler either is reset through a wiring short or losses the signal to the relay. ( I have seen it flash only once or twice and quit or stay on for a bit and I canceled)

In order for them to not work the failure would have to be in resetting the canceler. So could be a wire issue or in the unit itself.

Now I have somewhere to go with the debug. I had read earlier descriptions but somehow had it in my head the switch was momentary and was trying to figure out how the flasher worked on it's own.

Thanks!

EDIT - one note as I said above switches are relatively new due to PO having a similar problem so I won't rule them out but suspect them less than wiring or canceler...

 

Just a final update I found a reasonably priced canceler on ebay it seems to have cured my ills. Guess mine was getting flaky.
