Default 84 FXS, 4 way flashers possible?

Can the turn signals be adapted to use as 4 way flashers on the older bikes? Is it relatively simple? I have no problem with wiring in general, but I dont understand the method used to make turn signals into 4 ways on older vehicles, its just not anything ive had to deal with. Is a simple part from an older vehicle an option, such as, is there a simple module the wiring runs through that makes them all flash and doesnt backfeed to the ignition circuit?

They already have it... Hold both buttons!

I have a wiring diagram for 4-ways on a 4 pole ... [I think] double Throw Toggle.
I'll Look for it..
Don't know where one would mount it on an FXS tho...

Thanks, if you find the diagram it may show the way forward.

I wonder if the flasher control module for an older pickup may be adaptable?

The bike has an FL dash, there may be room to squeeze something in under the dash plate for a module, for a switch, Im not sure yet.

Gonna be a Big switch, as you must tie the two sides together to the existing Flasher, without them otherwise being tied together.
It was designed to be both buttons held!!!
There is a Diagram around... maybe late '70's maybe FLH had a Toggle for 4-ways... I believe...I never had one... My '83 FLHT needs both buttons Held!

Searches havent shown anything useful so far. Theres likely a fairly simple way to do it on a bike, Im uncertain how its going to work without backfeeding the ignition circuit with only a switch. I had an old Chevy that had the wiring burned up, with the way the wiring was repaired, if you turned on the flashers, then turned the ignition off, it would run..stop...run...stop...run...as the relay wasnt there or wired correctly.

I had an idea. I searched the hazard widget for a 93 Suburban (which I happen to have one sitting unused outside). The part costs $30-$50 if you buy one new. Anyway, upon figuring out it was a relay, it functions one way under normal conditions, each turn signal operates independently, but when the hazard switch is activated, it feeds both turns and cuts off the feed from the ignition. All the switch should need to do is power up the hazard side, it then cuts feed from ign to turns, and heats up all the turns run through the flasher. I need a wiring diagram to see if its workable with the bike wiring. Id be happy to discover theres a simple kit or method to do it though.

All For 4-Ways????
Then you can drive around with all 4 flashers on and flashing... neat look!!!
But Illegal.. and rightfully so.. Other than road guard duty... I see no need...and holding both buttons is simple, and effective...

Yeah, hilarious! Other than taking your granny to the hospital on your bike after she had a heart attack, there probably arent many reasons you would want to drive with them on, but its not entirely out of the question.

They would be as useful on a bike as on a car, perhaps more so in the case of safety and not getting hit when stopped on the side of the road. Stop for some reason, any reason, flashers to alert drivers you are stopped. Flat, breakdown, drop something in the road and pull over to get it, stop to help at a wreck or other rider broken down, dangerous junk in the road, whatever. Just holding the flasher isnt feasible in most cases, no more so than holding a flasher in your car, theres a good reason theyve had them in cars, and not much reason not to on bikes. I understand some newer bikes have them,

It not that complicated in any event. To wire something like this in isnt as complicated as rewiring the front end of the bike after somebody butchered it for different handlebars, repairing that, removing the rats nest of wire in the headlight and adding a bottom mount headlight and FL dash, none of which is particularly difficult. If I can see a wiring diagram on how it functions and connects, it should be fairly simple to adapt. A basic kit would be better yet. I found one that claims to be for metric bikes. Not sure why there would be a difference electrically.

But...last I looked... they are... this is Not metric, nor very "New"
Somewhere, I have a Wiring diagram for it... hell...when I get home I will draw ya one...
in the mean time Look at the schematic... the purple on the left handlebar switch housing and/or the brown on the right handlebar are what is being attached to the Green wire... which is the Flasher providing 12v thru it... 4 poles 1 each 12v and 1 purple and 1 Brown... all tied together when 4 ways are On... but completely separate [not Necessarily the green 12 v feed] when not in 4-way position...
I guess that would be a 4 pole single throw.... maybe

Nope I lied... I think a double pole...single throw will get it "C" here

OK, I think youre correct, the double pole looks like it may do it. If so, that would be pretty simple. I have a wiring diagram for the bike, so can intersect the wiring under the dash panel. I used all factory type pin connectors when fixing the handlebar wiring, if I can get 2-1 connectors, or double wire the turn wire connectors I can keep it simple and clean.

Cool, thanks for the info and thoughts.

Yes... it should work like a Damn...especially if you can find a DPST mini Toggle or some such...
with an FL dash the Purple and Brown wires are right there at the Indicator lights... simple...
and Green Flasher unit is probably under the Dash Mount [true FL way]... if not still in the headlight housing!!!!
