Harley turn signals

[Patrick]

This goes to show I'm not a Harley guy. How do the turn signals cancel on a Harley ?  Time or bank angle or some such thing ?  Goes to show what I know, I just found out they self cancel.

[Avanti]

I believe they work something like this:
The number of blinks, distance traveled, MPH threshold and lean angle all make up the algorithm of cancellation.

Doesn't that seem awful complicated for a company like Harley ?

I took the easy(?) way out, adapted HD controls to the Valk....an interesting project adapting HD wiring to a Honda main harness. I figured I was half-smart and could do this, and it turned out to be easier than I thought. First reason for doing so was I wanted chrome controls and sending the OEM units out was quite expensive and fraught with possible issues re. the sight glass R&R. I went with the HD controls because they were already chromed but also meant getting rid of the choke lever which turned out to be a real blessing, forcing me to come up with my current method that many have wanted to copy. Second, it gave me a separate turn signal button for each side....left turn is on the left side, right turn is on the right side. While wiring it all up, I installed a turn signal module that gives me total control and is self canceling. Timing ranges from about 8 seconds, then 20, then 75....depending on how long you hold the button. Also has 4-way emergency flashing as well. I've had it on the bike for maybe 10 yrs. or longer with nary a problem but took a while to get used to two buttons for turn signals. Honda is remiss in not designing their products the same way, the Honda method isn't revolutionary....it's old and needs to be reworked. I don't know if current Honda bikes are different, my '98 Valk is the newest bike I've ever owned and will probably be the last main ride.

Hmmm, that is a pretty neat way to do that. I agree Honda could/should do a better job.

Turned out to be easier than first thought, just took one circuit at a time. Got that circuit working and labeled it for the final assembly which I didn't do until everything was covered. The start button in conjunction with the kill switch was a bit of a head scratcher...works a bit different on the HD. To kill the headlight when pressing the start button was another issue to work out. I devised a double relay system in series, the first relay was activated by the start button thereby killing the light. The second relay worked off the power coming through the first one and was used solely for hi/lo beam operation. The first one was hooked up in a normaly closed state, the start button merely engaged it momentarily and killed the light circuit which ran off the second relay....which was also installed in normally closed state for low beam. That's because the majority of my riding involves the low beam so figured no need to have that relay engaged full time. If you hit the high beam it activates the second relay which is on the high beam circuit. Quite simple actually, I installed the relays in a small plastic box and laid it on top of the battery cover....along with a bunch of other stuff I've wired in.

engine vibration eventually moves the switch to off.

And I was thinking it was something complicated.  Gee, overthinking things again.

Hahaha.  Good one

On the Harley's I have wondered the same thing but for our bikes this works well.

They self cancel, 4 way flash,parade flash, and many other functions.
