8 fun kit died last night on way home :(

[KirstinS]

They didn't say anything - tbh I'm not sure they tested but just sent a replacement

I emailed them my woes last night - no response as yet

 

[shemozzle999]

I am sure they will sort it out.
It might worth suggesting you send both the battery and charger back to test them out.

 

[KirstinS]

I hope so - I don't deal well with being ebike less ! Maybe I need another as backup (wife will kill me

 

[jackhandy]

Why not have a Haibike fs just for sunny days?

 

[KirstinS]

I wish jackhandy, sadly all my ebike exploits are on a rather shoestring budget . Actually I sold an 8 year old brompton to pay for the kit

Until that lottery win comes in the haibik stays in dreamland

Sorry to hear that a fellow Brightonian is having so much trouble with his Bike, hope you will get satisfaction from the supplier, I did notice a advert on the local gumtree that may catch your interest(wife allowing) Electric Bike in West Sussex | Bikes, & Bicycles for Sale | Gumtree.com

Tested the fuses - 2 x 15a blade fuses by sticking current from 3.6v CR123 across it. As it read 3.3 volts on both fuses I'm guessing they are not blown and not the problem

Could a short in the led panel cause the BMS to pack up ?

You don't test a blade fuse with a battery. Instead, you look at it with your eyes and see if the little squiggle of wire between the two blades is still there. If that's not enough to confirm, you set your meter to beep, which is that little arrow-like symbol at 5 0'clock on your meter; test it by touching the two probes together to hear the beep; then put one probe each side of the fuse; if it beeps, the fuse is OK. Were the blade fuses inside the battery?

 

[KirstinS]

Ok d8veh will do that, jut assumed if the voltage passed across fuse then it could not possibly be blown

 

[KirstinS]

"the battery lead from the controller may loose and doen't lock properly will cause problems, if in this case, it's out of warranty."

Is what they said

Also fuses def fine, visually and tested

 

[JuicyBike]

"the battery lead from the controller may loose ..."

That makes sense Kirstin. If you could only get it to a specialist for a thorough check to finally eliminate that battery from the equation. Is there no-one down on your section of the south coast willing to have a look?

 

[KirstinS]

Update - I sent the battery, led panel and power lead to 8fun and received a new battery back a moment agao - as well as my original leads.

8fun confirm no issue with led or power lead but BMS had gone wrong.

It great they have replaced- again- but I'm concerned there is an inherent issue that keeps making BMS go bang

Still guess I just have to plug it all in and see , unless any wise folk can suggest possible root cause (appreciate I may just be unlucky and there is no correlation )

Hi KirstinS
I purchased one of these kits two years ago and though I didn't keep it long I know it is still going okay because I gave the kit to my sister after purchasing a Tonaro. I know this is only one other persons use but I thinks it is probably worth knowing other peoples kits are still working okay after a couple of years.

Good to know ! Sure it will be fine when problem is resolved

Sadly , when I set the kit back up last night I immediately got the same issues as originally ie the panel LEDs flash very fast indeed an turning on/off makes no difference

I did not run the motor for fear of blowing up BMS again

8fun have asked for controller and led panel to test now

I would have to give up at this point and get my money back.Then I would go look at
some of the ready made bikes.

 

[KirstinS]

Well I have used without issue for 9/10 months 5 days a week

It has been a good learning curve, I've learned a lot (multimeter use, trouble shooting, fuse replacement/testing just for starts)

I think 8fun deserve chance to resolve. If they were near to me then I could jut take bike along - but they are in midlands and I'm in Brighton.

Also my bike is a very nice and rather expensive bike I bought before the kids arrived. Can't be replaced and I could not afford an equivalent spec e bike


Still had the whoosh sport sorroco existed when I bought the kit I would have thought thrice....

 

[Deleted member 4366]

There must be a short somewhere. Main suspect is the lead from the battery to the controller unless the controller itself is faulty.

 

[shemozzle999]

I am sure your patience will be rewarded in the end and 8fun's methodical approach will find the problem eventually.

 

[KirstinS]

Well d8veh, 8fun say they tested power lead last time an all is fine? Any chance the led panel could be culprit ?

 

[JuicyBike]

Kirstin
I would be tempted to ask the supplier to send out all the parts that may be suspect, and then it should be simple for you to swap them out at the controller, identifying the defective part.

It would save you and them a lot of time and trouble. I'm sure they'd trust you to send back parts not required.

You should certainly disconnect brake switches and pedal sensor temporarily, but I'm sure you will have already tried this. Disconnecting the throttle and re-connecting the pedal sensor to see if either of those components are faulty may also help.
It is only the h-bar display that you have to connect for the bike to function, along with either the sensor or throttle (but not both), though others may know better.
Hope this helps - apologies if already covered / suggested (long thread to read... so little time...)

have you tested the motor?
