Title: 2016 Zero SR No display No lights No power
Post by: crosman on December 13, 2020, 04:19:34 AM
Bike is completely dead.  No dashboard display, no lights, no power.  Could be caused by water, since it happened after washing the bike.  Initially no lights on BMS LEDs.  Did software and hardware reset.  #4 LED now flashing green every few seconds, so all good.
Checked 12V fuses - all ok.  Checked Low Power B+ fuse and it was blown.  Replaced fuse and it blew as well.  Any help diagnosing what is causing problem would be greatly appreciated!

Well, you'd look (which the fuse is out) for the long on the B+ circuit with a continuity tester.

That should let you isolate which on that leg is stuck conducting.

Thanks!  Are there schematic diagrams available to help trace the circuit?

Not that I know of; they've changed their circuits a few times from '13 on.

Low Power B+ fuse blowing is often caused by a bad DCDC. Did the headlight turn on before the fuse blew again? My first step with these is usually to disconnect the dcdc, replace the fuse, and see if the bike powers up normally. If it doesn't, I've seen the dcdc damage BMSes and MBBs. Usually better this happens under warranty, because replacing all these parts adds up.

 Zero has worked with me on the cost before(I'm a dealer). New DCDC is a few hundred, MBB/BMS is usually about 600-800 each. Plus labor.

PS. Disconnecting the DCDC on the older bikes is a pain, its in the center of the bike.

Good luck!

No lights.  B+ fuse blows even with the key in the off position. I can hear it pop as soon as it's plugged in.

If the fuse popped, why would you pop a third one?  You know something is conducting that shouldn't be...

Try referring to the 2016 FX schematics here: https://zeromanual.com/wiki/XMX_Platform/Schematic
I believe the SR should be very similar.

Thanks for the help.  Decided I'm probably not up to the challenge of digging through the maze of wiring to diagnose problem. 
Probably better off trailering bike to nearest Zero dealership and let them figure out what's going on.

My bike is at the dealer right now for the same thing. I love the bike, so I wanted to take care of it. It seems even though the manual says you can wash it - YOU CAN'T. I rinsed the soap off with a slow and lazy stream of water and killed it. I'm really upset about this. May end up in court if it costs a fortune to make it run again. And let it be known, you must remove any and all aftermarket electrical add on's or the dealer won't even diagnose the issue. Not just disconnect, REMOVE. The only saving grace - I will rewire my add on's better the second time. It will never see running water again.

My bike just sat out in a storm because the tent blew off.  While charging.

It was fine.

'slow and lazy stream' huh?

I have always carefully washed the three Zeros that I have owned over the past 11 years with a garden hose and have never had a problem. One thing that I do is to blow dry the bike after washing with a leaf blower and then ride it around the neighborhood for a couple of miles to thoroughly dry it off and make sure that the brake calipers are completely dry, also.

I carefully wash my 2016 DSR every time it rains ;D
I ride every work day Weather or not.

No idea if this is the case for you, but I have seen some terrible DIY splicing jobs fail under heavy weather or washing. Wire nuts, poorly soldered joints, etc. Building a good harness is a skill most people don't have.  Often this kills the DCDC which can kill the MBB and BMS. Very expensive to fix, and this almost always voids Zero warranty. Probably looking at 1.5k in parts and 500-1kish in labor.

Thankfully they've nearly eliminated this in the newer platform by including accessory plugs with common connectors in the harness.

Dealers often require removal of third party accessories, as they can change wiring and lead to shock hazards. Again, nothing abnormal. I require that as well.

I could go on for days about the problems I’ve had with Zero, and this motorcycle. It’s had issues from the day I got it, and Zero has ducked out of every warranty issue I had. Every accessory I added was to make this silent bike safer. Better lighting, a better horn, and audible turn signals. All done without the use of wire nuts or tape. And all done while staying well under the ten amp accessory limit. And yes I’ve seen the videos of these bikes driving through rain all day long without issues, but this has not been my, or poster Crosman’s experience.
 The drawbacks of posting on a public forum. My terms, my sentence structure, and even my wiring skills come into question. My wiring was all done with a ratchet crimper and wire loom. My gripe is that it wasn’t good enough to simply unplug the bullet connector, effectively disconnecting all the aftermarket electronics, all point to point wiring had to be removed.
 Slow? lazy? I did not force water into the electronics of my bike with a pressure washer. However if these terms sound familiar, in that you feel the need to pull them from my paragraph and question them, then by all means, frame them and put them on your wall. Store my bike under a tarp or in a tent? Oh hell no, especially in soupy coastal weather. The entire post about charging in the rain has nothing whatsoever to do with my Zero issue, and is not relevant.

Aww, you say you washed it, it didn't work.

But you don't think being out in a wind and rainstorm sitting charging isn't at all similar?

Clearly, your bike shouldn't do that.  Clearly, others don't have that problem.  That's more evidence something is unique to your bike and not the design.

And yet you find this insulting?
