Hello all. New to forum type places. I just bought a DSR and has 500 miles on it. Never road in rain, garage kept, never down. I went to turn on and the display flashes when the kickstand is down, no normal boot up or display showing. When I do pull up the kickstand the bike will at least switch to ride mode and not give intermittent power pulses. I can ride but I have no UI except the side symbols. Zero tells me I have to take to dealer and won't help diagnosis with me at all. I don't have the time to take 2.5 hours away . Anyone experience this?

Has it always been like this, it hasn't been functioning normally while in your possession and then the fault developed? Did you at least see it functioning normally before you bought it? It could be something as simple as a loose connection to the dash, it's easy enough to pull off the headlight (just four bolts) and have a poke around yourself.

Hi there, thanks for the response. It just started doing this after 1 month. Ok yeah I'm about to check connectors now

[TheRan]

While having a quick look through the unofficial manual to see what connector it is I did find this page describing it as a common issue, however you say the bike is always dry. What about washing the bike, do you use a hose?

I've never washed actually but when I do, no hose just a rag and cleaning spray.  I checked behind light and nothing seems odd

Here is what FB group is saying:
It looks like the DC -DC is bad and isn't giving you the correct voltage out. I would replace the dc-dc and possibly the mbb. Because sometimes the dc-dc can fry the mbb when they go bad. Voltage needs to be checked and unfortunately the dealer has to look at it. That's just how warranty works. if no dash and lights, but runs: 12V DCDC probably has an issue or fuse of it gone.
In the past the 12V system converter was not designed for continues 100+ V input sadly...

[TheRan]

It surprises me that the DC-DC going out wouldn't cause more issues in your case, for example the lights and the ABS not working and throwing up an error light and code. However I don't doubt that the guys in the group know more than me.

Watching this video it doesn't look like it would be too difficult to measure the voltages yourself at the fuse block

[wdisty]

Yeah, same. I found this info might be helpful for others that end up on this post too.
Ill see if i can check for voltage readings and fuses. May end up just having to take as the parts will be expensive to do it myself. unfortunate i don't have a nearby dealer

When my DC-DC converter died, all of the lights went off, but not the dash display and the bike ran fine. I didn't even know there was a problem until I happened to notice that my headlight and tail light were out and my turn indicators were not working. I have a 2018 S.
