PAS sensor wiring

[Peeeg]

Hello i have just bought a broken greenacre cs2/16 ebike very nice, I was told the controller was defective, however on closer inspection the PAS has been butchered cable cut and re-connected. I have gone back to ebike as they have stated they currently cannot get PAS sensors and disc for this model and not sure when they could. I have enclosed some pictures, but basically does anyone know if these are generic 3 pin connector ie will any PAS sensor do ? Also the wiring they have connected the connector end to the pas sensor as what follows: So PAS sensor end yellow / orange / blue to connector end white / red / black respectively; does anyone know if this is incorrect so I can possibly re-arrange ? many thanks

Blue and yellow are probably the wrong way round. I know on the brake sensors, the Chinese used yellow as ground and blue as signal.

It's a generic pedal sensor that can be replaced by any cheap one. The only problem is that there doesn't seem to be a standard for pin configuration.

Unsolder those connections, then plug the yellow connector in to your controller and check that black is ground (check continuity to any other ground) and red is 5v (probably around 4.3v). If they are, solder them to the red and yellow wires, then check that the blue one changes from 0v to 5v when you bring a magnet to it. If it does, you can solder it too.

Alternatively, you can try the wires in all six combinations until you get the one that works, starting with red to red, black to yellow and blue to white.

Brilliant many thanks, ill try re-wiring as ultimately its the controller I was told was defective, but to be honest looking at this, if looks like a duck and acts like a duck its a duck many thanks

I would also say Yellow and Red are gnd & 5v respectively.

If your controller can make your wheel turn at 4mph with the throttle, there's nothing wrong with it.

Yeah thanks to be honest that was my initial thought so I assumed it was the alignment of the Pas ring but then found this horror show

Thanks

Can I assume that there is a good chance that indeed blue and yellow are round the wrong way ?

Never assume anything. That's what the guy did before you, and after all his efforts, it cost him the bike. Measure and test if you want your bike fixed quickly and efficiently.

 

[Peeeg]

Yep can't argue with that

When it comes to China wire colours ciphering them can be awkward.
Red or Brown is common for 5v, Black is usually Gnd but in it's absence Yellow is often so. Blue in this case is likely the signal wire.
Logic would tell me this is the likely order.

Thanks it's sorted

You are spot on yellow ground red live and blue was signal all working fine

Thanks for your help sir you were spot on blue was signal yellow was ground and red was live essentially swap blue and yellow fully working very happy excellent site !!!!!

A cheap and easy repair to get the bike working properly, shame the person who had it previously didn't know what they were doing or who to ask.

Yeah it was bought on the bike to work scheme and has very little use although it was being stored outside in a car port!!!! I was looking for what I can salvage to make another ebike for myself they had taken it to a "specialist" who said he'd repair it for £100 so they cut there losses and I bought it, I tend to convert steel road bikes so a MTB is a bit different for me and to be honest the cs2 is a really easy bike to live with, solid, plug it in , done; battery feels abit loose so a velcro strap will be purchased to be honest I'm going to use it; I may possible buy a 700c rim and change the motor over

One of the problems, not many understand simple electronics or how to test for diagnosis for simple China systems. Once you understand a bit more about the basic PAS systems and the adhoc wiring China uses you can often apply logic.
Probably an opening for various people to start as a side line in business but issue is not enough custom to make it work. Woosh carry out repairs as a part of their business plan which is not just involved in e-bikes but multi task with more then one business model.

On here advice is given freely for those able to follow simple instructions on how to test or carry our repairs, apart from a few consumable repairs can be carried out for less then a few pounds.
