SOLVED. Was the light relay.
Hello.
My lights jut stopped working, and the error shows as being the Lights relay. I've googled but all the threads I find don't end, so I'm left with no answers. I need this bike working for the next month so I have to get on this, and as I just bought a house I have zero funds to pay for the Ducati shop to fix it.
I'm wondering if it could just be the bulb? Would that cause the error?
If it's a relay, does anyone have a link to a workshop manual or Youtube vid (I have searched) showing where it is, the part number I need.
Or do I need to accept that I have no lights for the next two weeks and ride in the daylight only? I'm at the in-laws until we move in on the 10th August, so I have no tools or garage to do any work in.
I can go buy new basic tools, but I'll be working outside. Everything comes together to cause the perfect storm of crap! :)
Thanks.
Did you check the 15 amp fuse?
Yep, was hoping it was that but they are all fine. Cleaned the contacts just in case.
Relay part# is 541.4.010.1A. It is the same as the injection relay. I believe they're under the tank near the battery.
If you can get to them you could swap them to see if the lights work.
eta...do you have no lights at all, or just no headlight?
Thanks. No headlight, unless I pull the flash/pass switch.

So when you pull the flash switch the high beam comes on?
Will the lamp work just on high beam, or only when you play with that switch??
eta...if the headlamp comes on at all, it's not a bad relay or fuse. It's either a bulb or switch issue.
The main lamp (top) stays off, the passing light (bottom) comes on with the switch.
Switching to solid main beam does nothing at all.
You can match that relay at any decent auto parts store. If you want to check the relay, 12 volts to terminal 30, ground to 86. Apply 12V to 85 and power should be available at 87. Or just buy a relay, cheap enough to have a spare.

If power for the lamp comes from the relay, how can the relay be faulty if the lamp will light?
I am leaning somehow to a blown low beam . . .he has hi beam, no low beam . . . as easy as taking the headlamp down and replacing the bulb . . . from what I've read

He only has high beam in flash to pass.
I think he has a switch issue with the dimmer switch.

Pass position bypasses the relay. If high beam comes on with the switch and low does not then it is probably the bulb or switch.

I must be reading the diagram incorrectly.
The way I see it is the flash to pass bypasses the dimmer. The power for both comes off the same terminal of the relay from what I see.
Just to be clear, the high only comes on with the trigger, not with the sliding main switch that keeps main on all the time.

Nope, you got it right, I got it wrong. Sorry fingerpuk. When checking the bulb also look at the connector and follow back to where it connects to the main harness.
To the OP...
check the bulb and connection at the H/L connector.
I had the chance to test more.
Indicators and break lights are fine.
Bottom bulb comes on when pressing the flash/pass trigger.
Main headlamp is off now by default.
Top bulb comes on if I push the top slider to main beam (push it forward) AND hold down the flash/pass trigger.

I think you have a switch issue.
Yup, after last report it seems that way . . .
Seems that way. New bulb didn't help, I have a new relay to test but I'll look into switch gear next.
Actually I'll open up the current switch and make sure it's all clean, a new switch will take until mid September to arrive now as Ducati are on holiday.
Well the insides of the switch seem fine, everything is as clean as a whistle. Can't see anything wrong, sadly my multimeter got lost in the house move so can't test. I'll fit the relay tomorrow and see what that does.
get a $5 in the meantime . . . and install the new relay . . ..
So today I fixed it, the relay had popped out. Pushed it back in, problem solved. :)
At least I now have some spares :)
good to know . . .

Where on the Monster is the Relay located? I am having the exact same issue and believe it is the relay as well. I pulled put the Headlight unit and the connectors are fine!
It seems I have to remove the tank to find the Relay?
Any help would be appreciated!
