Title: Ducati Monster s2r 1000 instrument cluster Post by: Pleh on June 20, 2024, 11:59:23 PM Hi guys,
I know there have been some situations where the instrument cluster, due to moisture, starts creating problems with turn signals. I am facing this issue at the moment. I am interested to know if anyone has been able to repair it/fix the issue. Or at least does anyone have an el. scheme of the instrument cluster so that I can figure out where this turn signal "relay" is. thanks.

IIRC it's also in the owner's manual.
Member suzyj described that area of the instruments in detail, with pictures, while showing which "relay" it is that controls the fast flashing (when a bulb is blown). Find her profile in "members" and browse her posts. It's worth the time.

[thumbsup] I see that her instrument cluster is Digitech, mine is Magneti Marelli ... she seems inactive on the forum but I sent her private message anyway. Title: Re: Ducati Monster s2r 1000 instrument cluster Post by: suzyj on June 23, 2024, 02:11:30 AM I'm not familiar with the Magneti Marelli one. I would guess everything's done with one microcontroller. I'd be looking for eaten circuit traces for starters.

I was cleaning the board with contact spray, there were some small traces of something like "rust", I am thinking now to try and clean it in an ultrasonic cleaner, to see if it helps. I have Digitech and Magneti Marelli at the table; they are two completely different boards. I am not an electronic expert, so I was just trying to find the logic and some similarities, nothing. How were you able to figure out turn signal driver on Digitech? Title: Re: Ducati Monster s2r 1000 instrument cluster Post by: suzyj on June 24, 2024, 08:04:06 PM I traced the circuit from the connector to the driver chip with a multimeter.
I looked the driver chip up, and found it was an Infineon BTS711L1. After reading the datasheet, I figured I could disable the open circuit sense by cutting the status pins.

I looked the driver chip up, and found it was an Infineon BTS711L1. After reading the datasheet, I figured I could disable the open circuit sense by cutting the status pins. I believe that is too advanced for me :D I was looking at both boards and on Magneti Marelli I wasn't able to find anything that even looks like the driver that you showed in your photos.

I will disassemble it later and send you photo if this one is not good enough. https://imgur.com/a/2UqmjND Title: Re: Ducati Monster s2r 1000 instrument cluster Post by: suzyj on June 26, 2024, 03:32:37 AM At a guess, the powerSO-10 chip is responsible for driving the indicators. I'd be probing either side of that. I can't read the part number, but it could be something like this:

If you could tell me which "arms" to cut to prevent fast blinking, it would be great...thanks Title: Re: Ducati Monster s2r 1000 instrument cluster Post by: suzyj on June 27, 2024, 02:28:34 PM Just the diag pin.
