Hi GT people!
After making a deep detailing of my Breva 11 I faced some problems with my bike.

1. Right turn lights flashes 3 times faster then left ones
2. Dashboard indicates “!” And right arrow with bulb logo, but bulbs are works
3. After I turn off and turn on the ignition, everything is ok until I turn on right turn indicators.

I trued interchange my existing bulbs, but I’m fails with it.

Any thoughts to fix?
Anyone face this problem too?

What? 🧐

You have a lamp error. I doubt anything is wrong with your dash.

Are you using the stock type bulbs or did you try and insert LED lights?

I take lamps from left side and put it to right side turn flashers. After that problem is not gone.

I use stock lamps.

So, on other forums some people faces this problems and it causes dashboard failure :(
 
Here is the same problem with no final report.

Breva 1100 indicator problem.

Hi. Can any one help me with a fault in the indicators on a 2005 1100 Breva. Every thing is normal until I put the right side indicator on, at this point it flashers at twice the normal speed and the warning light comes on, also a bulb appears on the screen with a X through it and an arrow...

I had a similar failure on my 1200 Sport. I can't remember all the steps I went through but I know I went through 3 separate dashboards until I finally sent mine to Carmo in the Netherlands for repair. There was water damage in the circuits, they repaired the circuits and then applied multiple waterproof coatings.

One of my failures was the LCD screen (first failure) and then I think I had two that involved the fast blinking on one side, one of the replacements was purchased brand new and lasted a more than a year and the second one was purchased used and lasted a couple of weeks at best. The fix from Carmo lasted the remainder of the time I had the bike, which was a number of years.
 
Do a search on here and you'll find the Breva dash had issues with water ingress and damage to the circuit board. Someone did a great write up on how to get it apart and fix the condensation issue.
 
To be sure that is dashboahd and not the external wiring harness, before ship it, try to reverse left and right connections of lamps indicators just in the wiring connector at the back of dash.
 
Thanks to everyone for advices!

I made some actions:
1. Dry my dashboard
2. Switch blinkers circuit vise versa

Nothing changes. I will bring my dash to repair shop for diagnose and fix.

They only place I have ever seen who can do an expert proper circuit board repair on a Moto Guzzi component with a guarantee of their work, is Carmo in Holland.

Trust me. You want to send your dash there. They will first tell you if it is repairable and then give you a written quote.

Nothing I have ever had repaired by them, has failed again.

I highly recommend them.

Thank you for advice, but I from Russia. No way to send my dash to Carmo - there is no international shipping to EU available now.
 
I have many Russian friends from college.

I feel very bad about the way things are going in Russia lately. It’s got to be difficult for the people.

It’s the same here. The people suffer from the politician’s silliness and stupidity.

Well hopefully you get some luck with a local repair. I wish you the very best!

I’m actually very happy this week as my ushanka hat for riding my Ural this winter, just came!

Please, may you take some picture zoomed on the two black integrated circuits at the left of connector?
I want to see the part number written on them.

Ok, the biggest one it's an Infineon quad high side driver BTS711L1. Probably it's the driver of four turn lamps.
The fast blinking that you see is for both lamps front and rear of same side or for only one?

Yes, front and rear both, Right side.
 
Ok, now it's a bit difficult for me give you other instructions with posts. This integrated circuit drives the 4 lamps indipendently so I'm not sure that it could be burnt because in case of fault, only one channel should be halted. This depends by how are done the traces between IC and connector and IC to micro. So if you know some friend experienced with soldering of electronic devices, you can try to replace the BTS711L1 that is quite cheap, about 5€-10€, also continue to check if there are some soldering cracked or oxidated.
