TSDZ2 - Not Working

Hi All,

 

Just joined forum and am new to electric bikes.

Bought a TSDZ2 8 pin with the VLDC5 and thumb throttle from PWSPOWER in China along with a battery for my wifes bike.

Goods arrived OK and I charged the battery for 10 hours.

Fitted the kit to the bik without testing before hand - after getting all wires connected I then went for a spin and no assistance, tried the thumb throttle and again no assistance.

Took the kit off of the bike and tried the thumb throttle and the motor doesn't spin.

The VLDC5 lights up and all icons are where they should be according to the various pictures I've seen on the web.

Contacted seller and they said they'll replace faulty part FOC but need to know which bit is duff and suggested taking it to a bike shop so they could test.

So does anyone here know:

1, Is there something I may have missed?

2, Anything I can do to test the individual parts?

3, A bike shop that will be able to carry testing.

I'm based in Chelmsford in Essex

Thanks for looking.

Pete

The multi-pin connectors need to be pushed together *hard* all the way up to the moulded-in line. I'd check that first.

 

If they seem to be all pushed home fully, I would unplug them and look carefully to see if any of the pins are bent / broken.

Cheers - I'll check it all again when I get home - I've been through the loop before but you never know I may have missed something

Two things first what voltage is the motor and battery ? do you have a volt meter to check the battery output and is it the version with 3 sockets under the display with the throttle in the middle one, temporally disconnect the brake cut outs if fitted

PS not to far away lakeside if you really are stuck

Hi,

 

One possible cause, what is the speedo reading ?

sometimes when the sensor is not properly positioned they read a speed over the assist limit and turn the motor off.

Hi,

Thanks for the replies.

When it was installed on the bike and was ridden the speedo was dispalying correctly as far as I can see the display has all the correct symbols on it and isn't showing any errors. It's all off of the bike and I've just checked all the connections and everything is pushed home fully and the thumb throttle still doesn't work.

I've contacted the supplier informing them of my findings.

I'll let you know what they say.

Thanks

I do have a volt meter and checked, it's putting out 55.8V so assume it's got a voltage regulator somewhere in the motor.

I'm currently chatting with PSWPower and seeing what they are going to do about it.

It's not a rocket science install - clip the connectors together - makes sure there's no gaps and that the battery has charge and away you go.

Lets hope they do the right thing!

The tsdz2 48v does not like to be over volted display powers up but he motor will not run unless it has the 52 version flashed

Hi Peter,

Thanks for the info - I've got a light wired up to drain off some excess - I'll be checking it to see when it gets down to 48V.

The supplier has suggested I send it all back to Italy - I've pointed out it's brand new and shouldn't needa warranty repair. Since then they've gone quiet for over 6 hours !

I'll keep you posted.

Thanks for the reply,

Cheers,

Pete

So the display does everything but make the motor spin !

Hi,

I may have found the underlying issue!

I ordered a 48V 500w motor - they sent everything and I assumed (yes I know !) they had delivered a 48V 500w motor but NO they've delivered a 36V unit !

Yes I should've checked but we shall see what PswPower say about the mix up

Pete

That is a problem make sure you get the right one this time ps if you send back to Europe for repair the vat is charged both ways so would have been a nightmare

I had the same problem.

Have to burn off a few volts by putting it on another bike, with a Bafang 48v BBSHD on it.

The firmware on the stock tsdz2 is pants.

TBH the tsdz2 is a POS!

55.8v on a 36v it cannot of liked that, might make a good door stop must admit that i fell out of love with the tsdz and have gone back to bafang

Thanks one and all !

I've still not heard from pswpower so I'll give it untill Monday afternoon and then decide from there

Head office is on China time

Hi,

I've provided a ton of proof that they sent the wrong the unit ! - Just waiting to hear what they intend to do about it .. I think they've all gone home now. It's taken way too long to get to this point but I'm hopeful they'll do the right thing and send out a 48V motor.. Will update when I get more news from China.

Pete

I'm sending the motor back - pswpower are the WORST company to deal with ABSOLUTELY disgusted with their behaviour - They screw up and do NOTHING to rectify their mistake. AVOID them at ALL COSTS

Does any one here know of a decent company to deal with as I'll be sending the unit back and want nothing more to do with them.

It would've been so easy for them to apologise and send the correct unit out but no, lets go through pointless hoops and P*ss our customers off - utter morons

BBS from eclipsebikes, one can look to see if Woosh have any stock at all.

 

Like bikes, supply/ demand is high and there aren't many companies UK wise to deal with, so one is either at the mercy of China imports as a sole importer or the various online market places. Brexit is another factor.

Bought from Eclipse https://eclipsebikes.com/bafang-motor-kits-c-17_65/ many times.

Prices are good, UK based, quick delivery and aftersales service is superb.

Forget getting a TSDZ, they are dire! Bafang is a better, both in cost effectiveness and performance

With these Chinese suppliers, sometimes you need to negotiate in a diplomatic way. A good solution would be to buy a replacement from them at a discounted price and sell on your 36v kit so that the price you pay for the replacement is close to the price you get for the 36v one. I did that with a Chinese supplier once, but I can't remember what the item was. It might have been a hub-motor or something entirely different. I can remember giving them the Ebay link so that they could see what I got for it. In the end, nobody lost much, and it was a lot cheaper than sending back to China.

 

We buy these things from China because they're cheap and available. You have to be philosophical. In the long run, you're still better off dealing with them. I baulk at the prices some people pay from the UK, but then it's creating jobs for people, so you're sort of donating your money to a good cause, sort of like charity.

Post #11 states the 36v unit has been subjected to 55v battery source. Doubt that has done the TSDZ2 controller a lot of good.... Result difficult to sell? Or return

The only thing you can damage with 55v is the main cap/s if they're not rated that high. You know when you've done that because you either hear a pop or a fizz, then a lot of stinky smoke comes out.

As the controllers come in two flavours 36 & 48 volt, https://www.aliexpress.com/item/1005002281493283.html?albpd=en1005002281493283&acnt=494-037-6276&aff_platform=aaf&albpg=743612850874&netw=u&albcp=12555183349&sk=UneMJZVf&trgt=743612850874&terminal_id=ffc1bb07464d4ef4bd9fe0c1dc7bbe55&tmLog=new_Detail&needSmbHouyi=false&albbt=Google_7_shopping&src=google&crea=en1005002281493283&aff_fcid=fda8a581202d4b85a546b4517426e859-1619783324318-05187-UneMJZVf&gclid=Cj0KCQjw1a6EBhC0ARIsAOiTkrH9qtjJ_m8RjdvgAGphTNmZ0dhlzUEIhlPsbdpQDxX0PjQxM0A9UEcaAlVwEALw_wcB&albag=122168288289&aff_fsk=UneMJZVf&albch=shopping&albagn=888888&isSmbAutoCall=false&aff_trace_key=fda8a581202d4b85a546b4517426e859-1619783324318-05187-UneMJZVf&device=c&gclsrc=aw.ds

I would say that the 36v version is unlikely to have caps rated for +50v. Most electronics are built to a price, bulk savings can be made in lower spec components. Especially electrolytic capacitors, where higher specs are higher prices.....?

As I said in my previous post, it could be an issue trying to sell the suspect TSDZ if it cannot be seen proved working..... Just saying, other opinions are available!
