Hazard Lights Failure?

[BrunoGA]

I'm stumped. I have a 2015 LS XR3037H, just under 400 hours on it and runs great. Have not had any problems with it. However now my hazard lights no longer work. Both lights work for turn signals. I have checked the on/off switch with a meter, I've checked the fuse in the main fusebox, can't find any loose wiring in connectors or any bare/broken, shorted or mice-chewed wires.

Is there a relay I missed somewhere that makes it flash? Any other ideas? Thanks...

there has to be a flash relay to control the hazard lights just like a truck. would have no idea where to look though.

I believe there is a separate fuse for the hazards. Did you check it and not just the one for turn signals?

This is the what my MT240 has. See the 3rd one up from the right, ECU Power/Hazard, Yours may be the same.

Agree with checking the HAZARD fuse, as it's the easiest to fault-find.

Another consideration is that it could be an electronics fault. The timing of ON/OFF flashers is typically accomplished by an RC (Resister/Capacitor) circuit, perhaps incorporated in/on a circuit board... loose connection?

Thanks guys. I did check the Hazard fuse specifically, even swapped it for another one but both fuses were intact (and tested with meter). My fuse block does look almost exactly like yours Bearsixty7, ECU is separate from Hazard if I remember. I was thinking a flash relay or circuit also Grsthegreat, but did not see one. Will look again.

Just to get this straight - the turn signals still function OK ? I would bet on some type of flash relay or circuit problem when the rotor switch is turned to Hazard.

I think the flasher unit is under the right side of the steering wheel.

I have the same tractor (2014) and the hazard lights not working on mine is faulty switch internals. Usually if I turn the switch on and off several times they will start working. I should order another switch but haven't got around to it. Try turning the switch on and off rapidly several times to see if you get them to work. I know you checked the switch with a meter, so did I but mine is an intermittent problem meaning it worked when I meter checked it but not when I put it back together.
