Different Self Canceling Turn Signal Question

Postby newomij » Tue Jul 05, 2011 7:37 pm



Where do I start? My self canceling turn signals don't work at all. They don't even blink. I can operate them by pressing the switch lever on and off and on and off and....but they will not blink by themselves. I had this same issue a few years ago and I opened the housing, did some fiddling, put it back together and they worked but I don't know what I did other than maybe blow some dust away. I did change out all the bulbs to LED bulbs which draw a lot less power.

I ride an '82 Aspencade.

did you replace the flasher with a electronic type?

I didn't replace any flasher. Wouldn't even know where it is. If you can tell me where it is and/or if it needs to be changed, can you include a part number?

I believe that the original flasher is current dependent.When you used LED's,the current went way down.Thats a good thing,but the flasher doesn't have enough current being drawn through it to start the flash cycle.Using a NAPA generic electronic flasher solves this problems as it is not current dependent.It will flash regardless of the type of lamp used.
Take your old one with you and ask for a electronic version of it.
Here's a pix for placement of part.

Note: this may not fix the self canceling problem.Just get the blinkies working first. :)

Thank you for that info and diagram.
It's help like this that pushes Goldwingdocs to the forefront.
I'll get that original into NAPA this week and get it replaced and see if my flashers decide to respond.
I did take note that this part is for the flashing and the signal canceling issue will be addressed afterward.

A quick verification of the part...Locate it.turn on the key and blinker.I assume that it just stays on.Then unplug and plug in the suspected flasher,this will simulate it working and flash the lights.

Found the flasher unit and replaced with the led equivalent and the turn signals work as they should.
As I suspected, however, the self canceling function does not work.
It did when I got the bike some years ago and before I changed out the signal lights to led's.
What, if any, would be the next step to test the existing unit to see if it's salvageable?

Your self cancelling part of the signals is controlled by: 1) increased speed from where you turned the signals on (speedo sensor that couples to the self cancelling module), 2) turn angle sensor that is dependent on a pendulum device in the self cancelling module, and 3) a timer that shuts off the signals after a pre determined time period (don't know if this is current sensing or time sensing).

All three send a signal to a small solenoid in the turn signal switch to set it back to center slot.

So, you have a variety of places to check. I'd suggest getting a wiring diagram of your bike (PM me if you need one, I'll send you a PDF of the one from the manual). Trace out the wires and check all the connections and grounds. Open up the turn signal switch, clean it well with contact cleaner from electronics store and lube it with di-electric grease. The test it out.

OK. Lots to check. I'll update progress. Thank you for the directions.

2) turn angle sensor that is dependent on a pendulum device in the self cancelling module,

The turn angle sensor is a variable resistor(something like a volume control) mounted under the triple tree.It has 3 wires that go up through the steering stem and exit the top.The connectors for it are in the stem near the bottom.Use a ohm meter to test it.

Speed sensor can be 2 types.On the back of the spedo assembly,there may be a 2 wire magnetic reed switch that will pulse a signal to the auto canceler or a 3 wire electronic sensor that sends a signal when the speedometer reaches about 25mph. If it has another set of 3 wires,it's used to send a signal when the spedo is above 50mph to the rear air shock monitor.If the air shocks are low on air it will light a warning light .

Yes it seems that there is also a timer that lasts about 30 seconds.Being 30 years old,the timer components may or may not work well.
