Hazard lights not working when switch off

[Areshuan]

Hello,
I have a 1996 k1100RS.

Hazard lights used to work perfectly. They keep flashing even when the main switch is off.
Now they stop working unless the main switch is ON.
Any advice?  Thanks

Does the instrument cluster LCD clock work when the bike is turned off?

Fuse #3 is unswitched power to the clock and flasher relay.

Yes,   The clock keeps functioning when the bike is off.

Check to see if the flasher relay connector has 12V at the red/white wire (unswitched power from Fuse #3)

If you have power at that wire and still no hazards when the bike is off then it is likely that the flasher relay has gone bad.

If there is power in the red/white wire, could it be possible the yellow striped wire inside the hazard switch mounted into the dash pad has broken or has disconnected from where it was soldered to the switch? Maybe the blue striped wire disconnected and is contacting the yellow stripe's terminal. There is an excellent switch rehabilitation tutorial posted at this link, Areshuan. After you read it, you can scroll below the text and view photos within the Dash Switch Rehab link.

That's not impacted by the ignition switch.

The blue/white wire from the flasher relay does nothing on a K1100RS. That only exists because the first couple years of K100s had a lamp in the switch that would flash in sync with the hazards. There are only two wires to the later years hazard switch: Brown(ground) and Yellow/Violet that is grounded by the switch to activate the hazard flashing.

Thanks for the clarification. Never having owned a K1100RS needing this type of exploration, I picked up the idea of three wires from the diagram posted below where I've red-boxed the three wires. You might know where I got that diagram. Anyway, when Areshuan comes back with his results from testing for 12V at the red/white wire, or his results from the dash switch inspection, things should be clarified even more.

It doesn't what the wiring diagram indicates. It's just legacy stuff that is not how the later hazard switches are wired.

What matters is the ACTUAL WIRING on the switch. That's why I posted a picture of what the hazard switch connector looks like. There is no blue/white wire on any hazard switch made after the first couple of years of K bike production, only brown and yellow/violet.

And even if there were a blue/white wire on the switch it would still have NO IMPACT on whether the hazard lights keep flashing when the ignition switch is turned on or off

In the diagram below:
Left wire is blue/white - it's ONLY function is to illuminate the lamp that the early switches had. It has nothing to do with the operation of the switch mechanism.
Middle wire is brown - it grounds both the lamp and the switch
Right wire is yellow/violet - this sends a ground to the flasher relay when the switch is engaged to turn the hazards on.

A diagram should be accurate, especially if provided by a world-class shade tree mechanic. Not everybody is hip to legacies.

Thanks for the reply frankenduck.

I do have 12v. at the red/white  wire.  SO,  I guess i need a new relay.
At $100 fora used one. I think i will keep it as it is.
Many thanks for th information
