It'll be like photographing a Spaghetti Bolognese, but I'll probably give it a go.

Andy and I are having a fascinating bit of correspondence about red/black/blue > red/black/white and white > black/grey.

 

The result being that I have throttle/no pedal assist/no speedometer!

 

Roll on tomorrow,

Red black and white is nearly always speed sensor, though the same colours can be used for throttle. I'd bet that red, black and blue is the throttle. You didn't answer my previous question!

If you could post pictures here, I may be able to help. First, check the motor cable connector. Does it have 3 pins or 6 or 9 pins? Next, does your bike have a spoke magnet on the rear wheel?

Once I know that, I can tell you which wires go where.

Do you mean "Which type of pedal sensor and connector do you have? "

If so, I don't know.

Sorry.

I'll go and check now.

It's six pins and there is no spoke magnet.

6-pin connector: 3 large pins are the phase wires, 3 small pins are connected to the internal speed sensor. Leave the speed sensor unplugged for now.

Follow the pedal sensor cable from the bottom bracket to the controller box. It has 3-pin female connector. On the controller side, the corresponding connector looks like this:

 

 

Connect the pedal sensor.

The pedal sensor has a red LED on it. If you turn the crank, the LED should flash.

Switch on the bike, check that pedelec function is working.

Let me know the result.

Connecting the speed sensor:

If you manage to get the pedal sensor to work, the next step is to connect the speed sensor.

Follow the motor cable to the controller box. The speed sensor is connected to a 3-pin male JST connector which needs to be connected to this connector:

Okay,

 

I sent Andy a pic.

You sent me two pics.

Andy sent me a pic.

 

I'm working it all out now and will go back to the bike in the morning.

 

Many thanks!

lastly, connect the brake sensors. On the controller side, you have two identical grey/black 2-pin JST connectors:

Andy has gone home. I usually do out of hours support when the office is closed.

Do take one step at a time, it's easier to master the wiring that way.

I appreciate all of this.

 

I'll have to leave it till the morning now, or my wife will not be happy.

Parcel from Andy just arrived.

Lost me, what was in the parcel?? LCD or controller??

Both.

 

I now have three working LCDs

Mornin' all.

 

Well red/black/blue turned out to be pedelec.

 

It connects to red/black/blue at the controller.

 

Red/black/white is the only one left, so that must be speed sensor, and the only one left at the controller for it to connect to is red/blue yellow.

 

Trouble is now I get pedal assist again, but for only one half turn of the pedals, then nothing for the other half turn. This repeats over and over.

 

I also have no speedometer.

 

I've checked all connections ad nauseam.

 

I've cleaned the magnet wheel and the sensor.

Let's fix first the pedal sensor.

Check that the magnet disc still has all its magnets and it turns correctly together with the cranks.

Check that the LED on the pedal sensor flashes correctly when you turn the cranks.

If the problem persists, can you email support@wooshbikes.co.uk some closeup pictures of the pedal sensor and the magnet disc, and also of the old controller so I can identify it? I can access the support mailbox.

Frankly, I'm starting to think about the free bus pass I'll be getting in two weeks

Fixing things is easier if you and I are on the same page. Let's fix first the pedal sensor, when that works, then sort out the speed sensor. Leave the speed sensor unplugged. I need you to follow the suggested steps. There is a logic in what I suggested.

Well, scrolling up and down, I can see that we are indeed on the same page

 

As regards the bike, I'll go and have a look at the sensor in a while.

the main thing in troubleshooting anything is to keep the number of variables as small as possible. Let's sort out the pedal sensor first and leave the speed sensor disconnected for the moment.

Which means I'll have to take the controller and all of that spaghetti out again to disconnect it.

 

Is it really necessary?

I'd bet that you have the speed sensor in the wrong sequence. Disconnect it and see if the bike works properly. You must use a meter set to continuity test to determine e which of the red, blue and yellow wires is ground.

Sorry, saneagle, I don't understand any of that, but I'll go and disconnect it again.

Is it really necessary?

You shouldn't have put it all back together until it was working properly. Do one connector at a time. Use a meter to determine the connection sequence. Use logic. Test. Just putting random connectors together because they fit will only get you into trouble.
