Encodr and yellow wrench error message
Does anyone know more about the "encodr" error message?
There have been several posts on V about it:
I got this "encodr" error message today, several times.
At first I noticed that the yellow wrench telltale was lit whilst riding. I slowed down, and as I was approaching a place to pull over the wrench disappeared again. I accelerated up to 70km/h again, but it came back a minute or so later.
I pulled over, it disappeared, I rebooted the Vectux, and drove off gain. The yellow wrench reappeared and then the "encodr" message appeared as well.
I continued to drive on at speeds between 70km/h and 85km/h and the "encodr" message disappeared a few more times, but was more on than off. The yellow wrench was almost always on but did disappear once or twice.
The "encodr" was never on without the yellow wrench also being on.
The scooter was otherwise behaving completely normal.
Because I am planning to attend an AEVA meeting on the Vectux tomorrow, I am wondering if I can fix this quickly or if I can ignore it for a while longer. I have been planning a 200km return trip with multiple recharges for tomorrow and do not want to cancel it for no good reason.
The most likely cause of the error seems to be dust build-up on the encoder mirror in the motor.
A) Did anyone receive advice from a knowledgeable source to continue riding with this error message until a service can be performed? How long can you safely ignore this? Or was anyone told to stop riding immediately?
B) Can the encoder mirror be cleaned without removing it from the scooter? Maybe blowing it out with compressed air could clean it enough to work again. Or is the encoder mirror accessible to gentle wiping with cotton-bud sticks, without changing its alignment?
AFAIK special alignment tools and software are needed to install the mirror in it's correct position and to re-program it.
C) Is there any other way to fix this without the special tools?
D) Does anyone have these tools, or their exact measurements and is willing to share?
Thank you very much for any help you can provide!
happy to see that you've solved it.
and interesting to see the technology..
btw.. do you always service your vectux on a carpet, seemingly indoors? :-)
Hi Mik, you did another great job!! Thank you for the Info and the Photos.
My Vectrix is still on repair, but i can use another Vectrix from my dealer.
Greetings from Austria to Australia Mike
excellent job done! I was afraid even touching anywhere near the motor encoder. But with your pics and guide it seems like a straight forward maintenance task. I never had the encoder message myself but surely now I know how I could repair it. For the moment I still prefer Vectrix doing this job, but hey, do we know how long we can rely on their service. That brings me to my question, there must be a Vectrix service handbook somewhere. Wouldn't this be crucial for all the Vectrix service/dealerships?
I regularly have the encodr message - tallies up nicely with what Vectrix told me about dust on the encoder strip. I never knew where it was, and now I do for future repairs :D
Hi Mik, Hows your distance these days?
I had a weird clitch last week, While riding
at acceleration the fuel bars would drop, and on de-acceleration bars would go up... and at regen go to the top
it work similar to a vacumn gauge in a car and the Estimeter read zero the whole time no amount of rebooting solved it.
at night I plugged in ....No charger, fail again! same as last year. I separated battery connectors to kill the scooter, then reconnected, and gauges are normal again and charger is working. PHEW! that saved a month wait.
In answer to your question on charging at CP only,
I get an extra 10klms from the batteries,if I charge to 13/17, and meters are more accurate, I think by topping them up further some of the higher cells may go into reverse charge, what do you reckon?
I assumed this, because the scooter is weaker when fully charged. and the meters are inccurate.
It may even be software related, I have noticed a lack of performance each time I get newer versions
Incidently the software, firmware and connections are for sale, and I will be going back to the first version, too many clitches in the latest
thank you for sharing this and taking the time to shoot the pics, Mik! That is sure to be a repair project that will effect all Vectrixes sooner or later, and if it occurs later than warranty service is available, many of us will have to rely on your demonstration to get ourselves through the project.
Many thanks, my friend!! I have downloaded all 20 of your pics, and your text to a service folder for future use!
Wow! Thanks for the detailed repair photos, Mik!
I've received three Encodr messages in the last few weeks, and the last time I noticed that the motor cut out for a fraction of a second (as if power had been removed to the motor very quickly and then restored). I'm guessing that it's related, and now that I'm coming up on 5000 mi I should probably expect some issues like this, right?
For those of us who still have intact warrantees, has anyone had this repair done at a dealer?
was done on mine, problem solved
Altho it is conceivable that it is rotor dust it is not likely. The only way to tell would be to remove the encoder disk and check if there is a build up around the shaft seal. There is grease on the inside of that seal so I think its unlikely that dust could get by it. Is the disk rubbing on any part of the mirror housing? There is only about .040" (sorry I cant do metric) of clearance for the disk. Also make sure the shaft isnt moving axially (parallel to itself) causing the disk to rub. Other than that just make sure it is sealed with RTV when reassembling the encoder cover.
Thats alot of dust. Actually the motor cover is not that difficult to take off. Carefully remove the encoder disk reflector with small needle nose pliers. Remove the disk. Its not that difficult to realign and you can do it in the field w/o SW. Remove all the motor cover bolts. Gently pry off the cover. Make note of the spring washer position when you open it. See if anything is rattling around. You would not want to attempt to replace a magnet. Good luck.
Hello Mik, I would mark the disc ect. I have seen a seal fail and leave a dust. Make sure nothing rubs when you rebuild. Take care when opening the throttle the first time after the rebuild as they can sometimes run backwards!
The motor will not run properly if at all if not aligned but will not damage it. The pcb can be left in place.The disc is simply held in place by a tapered bolt
Edit due to reading the last post again
You could mark it if you want, but for every 1 mechanical degree that you are off during reassembly you will be off by 6 degrees electrically. The main thing is to set the disk at the correct height above the face of the motor cover so it doesnt rub on either side of the reflectors. Then you do the magic sequence and it aligns itself.
The disk spins freely on the shaft until you tighten it, there is no registration. By trial and error you could get it to run but you would never know if its at its peak setting or not. Altho acceleration and range would decrease. If you are way off the motor could run backwards or just sit there and make ugly noises.
Yes it can be set w/o special tools. Just make a shim that is 0.134" thick to space the disk. Set the spacer on the encoder cover, drop the disk on to it, then tighten the bolt.
Dont remove the PCB however b/c that does require a tool to set.
The shaft the encoder is mounted on is not a solid 'pipe' it is split ito two halves. The mounting bolt is tapered, as you screw it in the shaft is splayed out forcing it to tighten on the encoder.
