Victron Lynx Distributor Hack (Simple + Cheap Upgrade) | Getting The Lynx Fuse Lights Working 

That’s a good shout. So a USB to RJ10 cable? My Lynx doesn’t have a usb on it, but do newer ones have this?

Just splice a usb cable and rj10 cable together mate

Hi mate wich wires do you put together any usb cable

Perfect. They delivered mine nice and quick. Let me know how you get on. P.s it has its squiggly bits don’t worry 😉

Thank you 😊. Hope your build is coming on well.

@@WanderbusAdventures Slowly I'm afraid, downside of working away from home all week and only having weekends, did I glean from these Victron vids that you went with a 12v solar/ habitation system?

Hey Kevin, it is called a DC to DC converter - specifically a UBEC connector (buck). I got mine from thePiHut but I can link to an Amazon item if more convenient to you. amzn.to/3OGWZmD

Thank you. We are pleased with it.

Hey. It’s worked well - thankfully no fuse blows: so from that perspective I haven’t ‘tested’ it but otherwise it’s working well. No issues to report.

Thank you for your kind words. Glad to be of help. Hope your install goes well

Looking at the Lynx I would assume you connect the hack to the right of your first lynx. Then use an RJ10 cable (likely one in your box) to connect the right port to your second lynx.

Thanks Donny. We got away with the worst of it thankfully. Hope all is well your end.

Thanks John. Just a little hack :-)

Hi Michael. I know some people have put an in-line fuse on theirs. Couldn’t hurt to do that for sure. I just figured it’s such a small draw and the cable used is quite beefy compared to a rj45 that usually powers it without a fuse if that makes sense. It’s a worthwhile hack whatever you decide 😊

So once wired with no fuses the led’s should be red. And the centre light red also. Once the fuses are in the lights will be green: if one blows or is removed that one will be red and the middle light will be red. Unsure why yours hasn’t lit up. Which wires from the RJ11 did you wire up? Best of luck.

@@WanderbusAdventures I followed this video mate black was negative and yellow positive only a light on the ubec lights up

Have you popped a fuse in? Is the green light in the middle on?

@@WanderbusAdventures no lights are on to do with the lynx Only a red light on converter is on I’ve only just got it all set up and running but I’m one fuse short All I did earlier was put power to the lynx and a negative to see if I had wired correctly but it must need all 4 fuses to work correctly with power in and negative connected I’m guessing I will get all the fuses connected tomorrow and see if it lights up this time on the lynx I would have thought tho it would have shown a red light on the led on the lynx tho and not the converter lit up Very strange Unless I’ve got a dud unti converter

I’d have thought it would light them all up too. Might be worth double checking the join and connections on the RJ11 side of the ubec. Let us know how you get on.

Thank you 😊

There’s no such thing. So at the time I didn’t as the RJ10 wouldn’t have been fused. Since I did this Victron have also updated their written material and it doesn’t mention a fuse either. So am confident it’ll be fine without one.

@@WanderbusAdventures Thanks! Just trying to get my head around how everything works and the rules of electrics :)

Everything else is fused as you’d expect 😊. Good luck with your build.

These wires are so thin.....they are the fuse 😃

I’ve also realised the UBEC itself is basically a 3amp fuse. They actually are rated to different amps - so worth considering when buying.

Thanks for letting me know. I’ve added a link for another if you’d like to use Amazon but it is also available from the Pi hut. Hope this helps.

No problem. Thanks for commenting and watching

It’d be a cheap add on. For sure.
