Well I did the test ride, so verything went fine.
Half way of going to home, there is some lag of throtlle (on, off, on off.....).
So pedal back to my home and measure the 5V output.
Hmmm it seems the 5V is not stable, it will travel between 2-5V.
Anyone knows what is the problem?
Yes I know it's the controller but what part of the controller causing this problem?
Thanks!

Hi MAgic.....
Without knowing where you took the measurements, my recommendation is for you to turn off the battery, and careful disconnect and reconnect the cables from the MP3. The symptom you reported is a very common signature of a poorly made connection. It could also be a solder joint anywhere in the 5VDC string.
I suggest you immediately contact whoever you bought it from and let them know you are having a problem.
TTFN,
Dennis

Thanks!
I have measured from the front connector number 3.
Also from the nine pins connector coming from the controller.
I have an external controller, maybe this is a better option for reliability?
But has anyone lyaout of the motor wires and hall sensors?
Thanks!

Anyone?

As you have the external version, I assume your wiring will look something like this:

Your controller connections should also be labelled similar to this:
(http://www.arhservices.co.uk/GoldenMotor/BAC028controller.JPG)
Use you voltmeter to check the 5V throttle supply by placing the probes on the T1/+5V and the Z/0V terminals, and let us know what the measured voltage reading is, also, whether it is steady or varying up and down.
You should have eight wires coming from the motor:
- Thick yellow wire = Yellow motor phase wire (Ma)
- Thick green wire = Green motor phase wire (Mb)
- Thick blue wire = Blue motor phase wire (Mc)
- Thin yellow wire = Yellow hall sensor output signal (Ha)
- Thin green wire = Green hall sensor output signal (Hb)
- Thin blue wire = Blue hall sensor output signal (Hc)
- Thin black wire = Hall sensor ground (H-/0V)
- Thin red wire = Hall sensor power supply (H+/5V)
Double-check that all of the connectors are properly pushed together as Dennis previously suggested.

Thankf for replies! :)
No I mean have an external Goldenmotor controller laying here.
I want to replace the internal MP3 controller, because I don't trust it anymore :-[
The 5V output is very unstable, also it will travel from 2V to 5V.
It should be a stable 5 volt output?
-
Yes, the 5V supply should be regulated to a nice steady voltage of approximately 5V.
The obvious solution is to contact your supplier and explain the fault to them. If they agree that the controller is faulty, they should send you a replacement controller to put the fault right under warranty.
If you would prefer to use your external controller, you will need to make up a whole new motor cable to extend the leads from the stator to the controller using three thick wires and five thin ones as shown here:
(http://goldenmotor.com/SMF/index.php?action=dlattach;topic=4269.0;attach=5632;image) (http://goldenmotor.com/SMF/index.php?action=dlattach;topic=4269.0;attach=5632;image)
Then you would need to modify all the wires from the harness to enable them to connect to the external controller. ???
I would strongly advise you not to attempt the controller conversion, unless you fully understand what is involved, and have the necessary skills, wiring materials and equipment etc. to complete this modification correctly.

Thank you! 8)
I will send the shop an email about the problem :)
-
Hmm the seller doesn't reply :-\
-
The seller doesn't response, can I do the warranty via Goldenmotor?
-
You'll have to send an email to David (wyh@goldenmotor.com) and explain your problem to him.
He typically deals with customers who have purchased direct from GM China, the other GM dealers are supposed to look after their own customers.
If you didn't purchase your kit from a GM dealer it may be difficult for GM China to process the claim without proof of purchase etc., but let's hope that David is able to help you sort the problem.

Got reply back from GM.
Bad news: no warranty because I didn't bought from a dealer!
I think this is a very good excuse!
I have several warranty issues with other brands.
I didn't bought from the dealer even then I had warranty.
O well this is my last GM product....

I can't seem to figure out what this issue with warranty resolve is. In one post it seems you bought it from a "seller" in another it seems you state you bought it from GM China. Who did you buy it from?

I cannot understand why you are complaining you can’t get warranty support but are still evading my question. I am still waiting for an answer to this question and I have a few more..
1- Who did you buy your kit from?
2- Who told you that you have no warranty?
3- Can you provide the details of your purchase and any conversation you had with GM on this issue in private email to me Garysalo@goldenmotor.ca
I am certainly interested in who would tell you this and what the actual email conversation was.
It seems to me if you are concerned about your warranty and cannot get support, answering these questions would be easy. If you are going to continue to evade these questions than it would seem you have another agenda that is starting to become more obvious. I have heard in the past people stating they can’t get a response from GM China about issues. When I see how much email I get in a day I can only imagine how much email they receive . I'm not saying its right, but I can understand how difficult it could be to follow up on issues. That is why I created a support ticket system on my site. But to state GM has told you that you have no warranty, is something I have never heard of before and would like to look into further to find out what is going on here. There must be some reason that is not clear here and I would like to know what it is so we can all understand.
This reminds me of when I first really became an active member here on the forum. Its was full of people not being able to get email response or warranty resolve. Once I started asking people for details so I could forward them to my contacts I did help some people find resolve. But by far the majority of the people posting their complaints suddenly disappeared. They obviously had a different agenda. Ultimately helping these people out ended up a few forum members coming up with the avatar I use and in me getting my nick name "Super G". So if your complaints are legitimate, let’s get on with it.
If possible answering the first 2 questions here is fine but any receipt of purchase or private conversations with GM China would be better sent to me in private.

I haven't mentioned I have bought from GM China.
I have mentioned I have bought the kit from a non GM dealer from China.
I have answers now from the seller, we are now in working for a solution.
I have send David a mail.
He said: no warranty is possible from GM, because seller is no GM dealer.
-
Did you buy it from bmsbattery? I have a friend who bought a MP3 from there, very cheap.

That is why I ask. There is no obvious answer as to who you bought it from. You are quick to slam GM for no warranty service but still protect who ever it is you actually bought it from. If you look through my history of posts I have slammed GM China myself for warranty service from time to time, but I didn't hide any of the facts. It would seem you are doing everyone a disservice here by misleading people to believe GM is the villain when it is obviously the people you bought it from that are not proving a warranty. Now you say your seller is looking for a solution, but you didn't mention it here until now and still you don't state who they are allowing others to fall to the same fate.
The only one you are protecting is the one you were actually having a problem with and the one you are making look bad is GM China who really has nothing to do with it.

I am just honest.
David from GM really said: you have NO WARRANTY because seller is no DEALER!
The seller is BMSbattery.....happy now?
I am glad the seller response, it has been more then three weeks now.
And I am still waiting for further response.
I have got one response back: he said I have to wait for several weeks for the replacement.
I have send him email back how many weeks is several weeks.
So you can say I am still waiting for solution.
Why is GM not responsible for warranty?
Here in europe you can also ask factory for warranty if seller is cooperate.
I have many times sellers are not cooperating for warranty.
So I did the warranty direct from factory and it went well..........
-
Thank you for the information. Sorry if it seems I was giving you a hard time. I suspected that was the seller as I have have several people buy replacement controllers from me that purchased there MP3's from BMS Baterry. At the price they are selling them I would imagine GM is not giving them replacements for any warranty issues. The warranty is completely up to them. I have no doubt this is why David told you no warranty for you.
People have told me they could not get warranty help from BMS Battery and were told if they start a PayPal dispute then there only option is to send the entire kit back to china for a refund. After reading the "terms and conditions" on their website it seems to be the case. Actually any surfing on their website brings doubt to any professionalism. Most of the information in there "information" links is sketchy.
Most likely the reason you need to wait is GM China is completely out of replacement controllers. From the information I have it seems I have more controllers in stock then they do. I hope that is the case and they do follow up with you.
Please let us know how it turns out. It seems you will need to keep trying to contact them by email. If you try a PayPal dispute you will have to ship it all back to china. This makes me wonder what they do with the kits they do get back.

Sorry I did not respond to this part of your email. It seems it was added while I was writing my last post. I was responding to a few emails as they came in so my post was delayed a bit.
I'm only guessing but the lack of warranty from GM for you must have to do with the price BMS Battery is selling them for. I'm not sure why BMS Battery even has these motors. I noticed when the MP3's first came out I was promised I would have them in stock when the release date came. When GM china did release the MP3 I did have stock on hand and was able to start selling them the same day. But it was pointed out to me by one of my customers BMS Battery was selling them before we were. I found this very odd. Were they the test batch of MP3's that were rumored to have been made. I did hear from somewhere that china did a pre production run of these motors that was not so successful. Maybe that's why yours has a bad paint finish. The motors I have seem to have a very high quality paint job. Unfortunately alot of them have a few minor scratches from assembly and spoking. But still the finish on the motor is very good.
One easy way to get some some idea of when your kit was made is the colour of the numbers on the wire harness. Have a look at the 4 way plug where the throttle, brake levers and buttons plug into the 8 pin wire. Do you see the numbers 1 2 3 4? if so then what colour are they? White or yellow?

Okay I have receive the replacement controller today :)
I have have a look at the controller, because I was mad I have stored it up at the attic ;D
-
Here is a link to a controller swap video I made.
http://www.youtube.com/watch?v=ofXCj_Dd10U
Be carefull with the Phillips screws. Be sure to use an exact fitting screwdriver and don't drop any into the motor. That would create a whole new issue. Hopefully they sent you 9 replacement screws a replacement o-ring and controller wire clip.
Gary

Well I am a tool freak.
So I have a big collection of screwdrivers.
Nope only controller with wiring is supplied.
I keep this controller as spare.
Because I am using Kelly controller after using a GM external controller.
I like the Kelly one better because of the rich feaures...
Anyway thanks for your link!
-
The connector has yellow marks, so which model is this?
-
The first released MP3's had no numbers. I assume these were the pre-released models as the first two motors I had about 4 months before the release were this way. When the motors went out for public consumption they had white 1 2 3 4 numbers on the wire harness. Several months after that they had yellow numbers. There was a wiring change at that point that if you mixed the white and yellow numbered harnesses you could have problems. Now more recently I have noticed the wire harness numbers are a whitish sort of lime green. More green than anything I guess but very light in colour. Whether this colour change means anything I don't know.
So if we count each change as generations. I would say no numbers as first generation. white numbers as second. Yellow numbers as third generation and Green numbers as the fourth generation MP3 wire harness.

It's no problem. Let us know if you get your MP III on the road. If they didn't send you replacement screws be carefull with them. This is what I send out with every controller.
