Blue, Red and Black Here is an image of the old controller

I've finally managed to get the bike up and running but just cannot work out the PAS wiring Don't know if anyone would know from the image attached?

Right. Just an update. I have been in touch with the supplier of the controller unit and they have provided details of the wiring. Herewith attached is an image of this which may be useful to someone in the future I do however, have some questions. 1) There doesn't appear to be any...

Ok. Left the bike switched off for around 30 minutes and it now seems to work as it should. Have no idea why.?? I have to make good all connections now so lets hope it work once that's done ????

Right. Have just reconnected everything again and am finally getting power to the motor. Turning the throttle works and we can hear the motor spinning, but not the wheel. Any ideas???

Right. Have just re-connected everything, including the ignition wire as suggested, and I now have voltage at the hall sensors. So a step in the right direction at last. The motor still refuses to do anything though. Not even if turning it backwards as before ?? Just another question. The...

That's 'sods law' isn't it? I've just removed everything and put the bike back in the garage. I'll give that a go. My original controller didn't have this connection so, like many of the other wires, thought it was redundant. When I have a bit more time I'll re-connect, including that...

No I haven't. Didn't know I had to as there isn't one on my original controller

Hi Yes. I have sent them a couple of emails to see what they say I have even been to our local Chinese take away, but the symbols on the packaging are in a different language format for them to translate.

Just an update. I have today received the new controller, fitted it and nothing. The new controller wiring was completely different, except for the motor and power connections, and the instructions were only in Chinese. I have therefore had to to guesstimate the wiring based upon my old...

Thanks for the information d8veh I have ordered a cheap controller through Ebay, so will wait for that to arrive and see what happens from there. Hopefully that will rectify the problem? I must say with my luck I won't hold my breath !! Thanks again

Thanks for that. I was just thinking that when I was checking the voltages across the hall sensors then surely I should get a reading when turning the wheel forward also? That's not correct then? I did check the magnet by the crank but, has I expected, made no difference whatsoever. I did...

Just an update. Have been having another go at it today and, by chance, noticed that the hall sensor check via the green, yellow & blue wires will only work when rotating the wheel backwards. I can confirm that all sensors record a voltage of around 4.5 volts dropping to zero. Nothing registers...

Right. After avoiding the problem all day I recovered the bike from the bottom of the drive before the scrap men came and tried again, but still no luck. In the meantime I have ordered a cheap controller through Ebay and will see if this makes any difference? When the part arrives I am thinking...

I have now given up on trying to fix the problem that I have left the bike at the bottom of the drive in the hope some local 'tatters' will take it for scrap If someone has any further ideas before this happens please let me know and I'll give it another go !!

I have tried connecting they Grey wires and the only thing that happens is that the speed of the rear wheel decreases, so assume it's a 'speed limit' circuit. I just disconnected the hall sensor wiring and, just as I thought, nothing. It obviously won't run without this circuit. Once...

As mentioned in an earlier post I did test the hall sensors with a multi-meter, and by rotating the rear wheel the voltage fluctuated between 4.5 volts and 0 volts on each which indicates they are all good. Correct?

Hi Just tried that and no joy. Still the same.

Yes. That is the same controller. There are twin white/black wire which run to the brake levers. The others, which look black in the picture are grey and aren't connected to anything. If I recall correctly the wiring consist of the following Power In (Thick Red & Black) Brake Lever (Black &...

Just some more information that may be of use I have spent quite a bit time going over the connections and wiring again this evening and all seems to be fine. The only way I can get the wheel to turn is by pulling it rearwards, sometimes by a full turn, and then it will start and change speed...
