A few tech questions
« on: August 28, 2017, 06:33:19 AM »

There are a few things I would like to know about my new Zero Cycles (2017 DS ZF 6.5 & 2017 SR ZF 13 with Pwr tank).

1. Where does the low voltage (the 13.8VDC) come from?  I think I heard mention of a DC to DC converter, but I also see several wires leaving the battery on the very difficult to read small schematic that I got from the Unofficial Service Manual.

2. What are those extra wires from the battery (left side of battery on the small schematic) Is there more than just battery cells inside the battery?

3. Is it possible to get a better schematic diagram? 

4. Is there a way to get to the 13.8 VDC when the key is out? There are several reasons I want an always on low voltage lead. I even like the horn to work while the key is still in my pocket. And a much better horn, of course. The stock one is a joke. I even consider it dangerous, I can yell louder than that weak beep! IMO, the rest of the bike looks like it's very reasonable quality.

Thanks in advance for any tech info. anybody here can give on how these bikes work.

Yes, there is a DC-DC converter. You should be able to easily find it with the search utility. It's a Sevcon unit.

Not sure which wires you're talking about, but yes, there's a BMS (Battery Management System) inside the battery modules as well as the cells themselves. Search for "BMS".

3. Is it possible to get a better schematic diagram?

Sure, as soon as you create it. In the meantime, you might want to thank Burton for his time and energy running down every single wire and connection on his bike. It's not as simple a task as you might think.

Horns and always-on power have been discussed extensively. Please use the search utility to find those threads.

I meant larger. The only problem I have is it's too small to see much detail. And I am too new here to even know who Burton is. But what makes you think that I would think making such a schematic would be easy? I would expect it to take months of hard work to trace out the entire bike.

But thanks for the info.

I , using the search keyword "always" to find it.

You can see the schematic in PDF from here: http://zeromanual.com/index.php/Unofficial_Service_Manual#Schematic
That way you can zoom in on each section to read it easier. I use it on a tablet with foxit PDF and pinch zoom in/out  as I am reading it. Much easier than printing it on multiple sheets of paper and taping it together.
