You can easily tell if the contactor is closed by measuring the voltage on the two large pins on the accessory charge connector. If you can read pack voltage, the contactor is closed.

I believe the way the ignition is wired is that 12V comes from the BMS to the ignition switch and then is read by the MBB. If it's that easy to reproduce, I'd see if I can measure the 12V on the ignition at all times.
If you can, then I would suspect your MBB. If you can't, then I'd suspect the BMS. Finally, it can't hurt to check continuity across the ignition, maybe there's something odd there.
Thank you for the hint, I will do the measurements, beginning next week and try to follow the ignition key cables and report back.

Does the contactor click open when you key the bike off (after successful handle-starting it)?


Yes, I  it does (more silently, I believe I hear it).

But maybe I can measure it somewhere ?

Zero Motorcycles Forum | 2013+ / Zero FX 2013 turns on only once after removing/inserting the battery
« on: July 16, 2021, 02:44:52 AM »
Hello,

I got an old black FX-2013 bike, everything fine so far, except one failure:

1) If the turn on with key it closes contactors (clicks) and I can ride it as expected.
2) If I turn it off, and then on again it does not close the contactors (or more excact I hear no clicks) anymore and it does not move.
3) If I remove battery modules manually and slide it in again -> goto 1)

It is the same if I use one battery or the other or both.
I can use it, but this is uncomfortable.

Anybody has seen this behavior, what could it be, what could I inspect ?

Any hint or guess is appreciated.

I just installed moto-sw ones on my SR 15 , even they are Foto DSR.
https://sw-motech.com/Produkte/Schutz/Handprotektoren/KOBRA/4052572026465.htm

They fit well with my wind shield and in my opinion also to the Zero Design, even a bit large...

Yes the ETH Zürich is kown as leading technology University in Swiss and Europe and the design by ZHDK is also cool.
and the bikes moves.

What me wonders is if the 1260 oild-cooled/heated Li-Ion batteries can perform so much better then the Zero LiPo cells, maybe a battery Guru can answer this ?

BTW.: I ride my Zero SR ~16kWh on contry roads (few motorway kms) hillside about 200km+ at 80-120km/h, so this would be twice the performance maybe 30% more in the city.

For people which have problem with their site, here the youtube video:

Recuperation and temperature management is listed to make this possible...

Do you think it is serious ?

Zero Motorcycles Forum | 2013+ / Re: Zero XU 2013 - strange noise - belt drive wheel broken ?
« on: November 22, 2018, 12:12:57 AM »
thanks for the guess, It is now my guess too, after studying some forum threads and manual und your post.

But I cannot figure out how to correctly measure this and adjust without software for calibration.
I phoned my dealer and he said there is a special software needed to do the adjustment and store it in the controller, so I visit my dealer tomorrow, maybe he can retrieve the failure with the zero software.

Hopefully the encoder has not been wrecked by my harsh re-movement of the sprocket, it stuck quite hard it was loctited and since the motor screws has not been in place, the front has been twisted.

PS: I checked the polarity and cables twice.

Now I got time and take courage to do the repair myself, and after some troubles unscrewing and  organizing the right tools, I got the sprocket to be replaced by a new one. The old one was too ruined to be fixed.
First trying without removing the motor didn't succeed, since the sprocket stuck to hard, so I build out the motor.

Afterwards  as a first power up, the XU looked fine, but after the first small  throttle the wheel turned a little and then the sevcon controller resets until it gets on again, seeing green light flashing than green stays and hearing the contactor in the sevcon clicking off and on. It stays reseting periodically ... but if the motor is turned to a certain angle, the sevcon stays on until I turn the motor again to another position.

So what I messed up ?

It checked all the connectors to motor including the black multicore, and I am sure I connected the phases in right order (since I made a foto before).

I could get out the error log via mobile and there is the repeating sequence below:

Zero Motorcycles Forum | 2013+ / Re: 2015 SR still not fully charging ...
« on: September 24, 2018, 01:18:16 AM »
Confirmed, just measured max Voltage during a charging cycle and it stopped at 95% and 114V.

To get sure I used a Voltage meter with Max/Min function over charging period.

I cannot believe the charger will break within 3 years, I think more it needs recalibration.
I will ask my zero dealer if he can do this ?

Better would be an how-to for DIY, if it is not to complicated, since I don't want sent in the whole bike and also don't want to be without charger for some weeks.

a) Try to recalibrate the charger, maybe a trimmer potentiometer or like this ?

b) Adjust settings via CAN or so if possible ?

PS:
Bike History for me: I bought this used  bike on 6.May from my dealer with new batteries installed and where the issue first appeared from the very first moment, he said it will take time some charging cycles until I get the full capacity... so I waited, but it didn't and 95% was good enough for my needs.

Anyway I am on the waiting list for a Diginow wich replaces the onboard charger, but I want to get sure it is not the other parts of the bike.

Just as my SR 2015. If you look at the battery voltage  when charging, you’ll see that the onboard only charges to perhaps 113 or 114v where as the delta quiq charges to 115 or 116v

Upcomming charger faliure!!! (Probably)

Thanks for the fast answer, I will check this next time charging and report.

Did your charger fail after that behavior and if yes how long did it take until it doesnt work anymore ?

Zero Motorcycles Forum | 2013+ / 2015 SR still not fully charging ...
« on: September 23, 2018, 01:35:01 AM »
I know it was discussed in other threads but I searched the forum and found no answer to this and it is a kind of different with these symptoms:

My 2015 SR, with Battery pack 2017 and power tank 2018 only charges to about 94-95% with stock charger. If I plug it out and in again maybe I get 96% or 97% on the dash.

If I add an external charger DeltaQ on the aux it charges to 100% (on my 2013-XU it is vice versa: DeltaQ stop charging before the on-board charger at 98%).

All firmware was updated by my dealer (see below) in June, so the firmware issue should be solved.
I also have this behavior on different charging locations, at home, at work and others, so it is not the power supply.

Anyone experienced this and could it be the on-board stock charger not fit for newer batteries ?

Thanks for the info,

So I ask if at the workshop they can spot-weld it again, maybe it was not spot welded good enough, since I saw a welding point outside not inside.

Thanks for advice.

The front sprocket isn't easy to change. Terry weighed in once, as recorded here:

https://zeromanual.com/index.php/Unofficial_Service_Manual#Front_Sprocket_Removal_.2F_Swap

The 2013 XU's power and torque output are pretty low (through a Gen2 Size 2 controller) so you may be able to limp, but I think we'd all be guessing at this point.

 I read the the manual and decided to fix in a motorcycle workshop, since they have higher quality tools (to remove the motor), but I have to convince the mechanic at the workshop to do this, since they do not repair electric motorcycles normally, so I print out this part of the manual, since my zero dealer is out of battery range.

In the meantime I fixated the loose side part of the sprocket to the motor with a metal tape and some silicon glue, so I can drive safely within the city, since I hope the side part is not essential.

Does anyone know how the side part  is fixated on the sprocket, I guess spot-welded, maybe we can repair the sprocket ?

---

PS: since I am not native English, in the manual as tools are listed:  "27mm socket, 3mm Allen key, 10mm Allen key socket "

What is the difference between (or German translation of)  a socket, an Allen key and and Allen key socket ?

Zero Motorcycles Forum | 2013+ / Zero XU 2013 - strange noise - belt drive wheel broken ?
« on: July 25, 2018, 02:56:40 AM »
When noticed a strange noise from below when start driving, I first thought on the rear break, but
when did a closer look I saw a metal ring between belt-drive and motor, which is part of the belt drive sprocket, I think, loose (see photo)

So before I start dismantling the bike I ask for your advice:

- Is it dangerous to drive with this for small distances (eg. to my shop) ?

- Can I fix the sprocket myself or do I need an exchange ?
 
- Any special tools, skills if I remove it and fix it again myself ?

What about switching 4 Packs from parallel to in series and charge with DC directly ?
Needs a big switch and  some Controller ...

Keep in mind your "big switch" would need to be able to handle the maximum current, just like the main contactor does. That's well over 600 amps at full throttle. Big switch indeed.
...
Making mechanical OR electrical switches at these current levels is no joke.

True, but needs switching only with power off, a Kind of recabling which could be done more easily, but still a challenge... But  maybe less than a buck converter...
