Motolights were working; Not now...

[stevebeaxter]

Hi guys...

Forgive me if the answer to this is already elsewhere - I did try and search...

This is my situation:

I just installed Lone Rider Motolights on my 2024 R1250GSA. They scanned perfectly and both were working. I then decided to add the extender cable. The right light disconnected. I scanned again, only the left one showed up, the right was showing in diagnostics as 'Disconnected'. I reverted back to the Y-splitter without the extension leads (the exact configuration that was working at first), and still the same problem.

I disconnected from the battery, did a reset, powered it back up, scanned again... Only the one light showing up.

I have checked and doubled checked the connection and there doesn't seem to be a physical issue. Cery frustrating given that they were working perfectly fine right up until I added that extension.

I'd appreciate any help.

Thanks

If one light is not working (not sure what this scanning thing is) switch lights right to left and see if the problem moves. If so its the lght, if not probably the wiring.

Hi Steve, Jim

Just to add to this in case it ever comes up as a search result. The basics of troubleshooting here would be the following:

• First, are both lights working when connecting directly to the ezCAN white output (individually). If yes, ezCAN's ezBUS output is working as expected and we can move on. If not, that ezCAN has an issue on the white output and needs to be replaced.
• Second, if one of the lights is not being detected when connected directly to the white output, and the other is, that light is the problem child. If both are working, we move on.
• If you now add the extension cable, connect both lights individually to the extension and confirm both are detected fine with the software. If both are not detected, safe to assume that extension cable has an issue. If both work as expected individually, we move on.
• Now add in the splitter, if one of the lights don't respond, first swap the around and check whether the issue persists on the other light (they can be identified by serial number in the "Scan ezBUS dialog window"). You'll most likely find that one side (or both) of that adaptor is the problem.

With all this, it is pretty straightforward and simple to identify the issue at hand. The only confusion that can come from this, is failing to follow all the above, or extremely rare cases (more on this below), other than that, you'll narrow down the problem to either the ezCAN, extension cable, Y-splitter, or motolights.

We've had 1 case where both motolights were problematic, out of the thousands out there, you can imagine the minuscule chance of this happening. We authorised the ezCAN replacement (of course, with no lights detected we assumed the ezCAN was at fault), only to realise this wasn't the issue. Lone Rider sent him a complete new kit and found that both the lights he received originally didn't work. The chances of that happening is less than 1/100, so I wouldn't expect to see another case like this in the foreseeable future.

Other than that, this should serve as a handy guide for anyone who is experiencing trouble.

Kind regards and safe travels
