Lights failure

[Malcvtr]

I was fitting a cheap eBay tail tidy to my 2018 Monster 1200s this afternoon and checked indicators and number plate light were working before tightening up. To make a long story short, here's my problem:

1. New number plate LED now not working when it was working before I tightened everything.
2. Tail light not working, but brake light and headlight are fine.
3. Taking things apart, I saw that two bullet connectors for the number plate light were touching: their plastic sheaths had ridden up.

So I thought I'd blown a fuse, but in the manual it says there's only one 5 amp fuse for "Lights", so with the headlight working it must be OK?

But when I reconnected the previous number plate light, it wasn't working either.

I asked AI for thoughts and it said to check the 10A fuse for BBS module which is allegedly what manages power to the plate light and tail light. Checked. Looked fine. Swapped it anyway. Problem remains.

All thoughts much appreciated. Thanks.

Can't help I'm afraid but I see you have raised the same issue on the Ducati forum so hopefully someone will be able offer some helpful advice. I fitted an Evotech tail tidy to my 1100 Monster and was astonished that everything worked from the off.

Good luck

Thanks. It's a bit of a mystery. I'll keep exploring and hope I don't break anything else

You will not believe this.
Or maybe you will.
About ten minutes ago, I decided to pull every fxxckin' fuse whether it had anything to do with lights or not.
Pulled a 5A fuse listed as "Control Unit" in the manual.
Blown.
Replaced.
All back to normal!

Write to ducarti, and demand a rewrite of the manual

Explain that the rear lights are controlled through this fuse, and not through the other fuse

Sit back and feel like a boss

I'll sign it, "Pissed Off C*nt from Cleobury"

It's unsurprising really as other model manuals contain similar errors/contradictions. Mine gave different rear preload settings to their own workshop manual, which would have resulted in bottoming out if I'd used them. I'll forgive it though as a quirk of translations and the fact as they update models, some of the information is out-dated. On the whole, I'm pretty happy with the bike itself, which is great.

Glad that you are sorted, frustrating as it was

Thanks. It certainly was a pain in the arras
