Yeah, I believe it is a 12 magnet one.
The 12 magnet discs often give problems. I've solved it before by pressing out every second magnet to convert it to a 6 magnet disc. The number of magnets doesn't make any noticeable difference in response or performance.

I am trying to find a manual for this LCD which I bought together with the Brainpower controller. I have the bike running but the speedo only works when the motor is running which is probably due to having no white wire from the hall sensor, I could fit a wheel sensor and connect to the controller but I guess I would have to disable the existing speed read out. I have also found that when I plug anything into the lamp output on the controller I get an error code 8 or 10. Here is what I have on the LCD menu some of which I have worked out:

P01 - 001 to 003 Screen Brightness

P02 – Miles or Kms

P03 - Volts 24/36/48

P04 - Speed Limit

P05 - 0001 or 0002 PAS Level Start up

P06 - Wheel Size

P07 - 0 to 100 ?

P08 - 0 to 100 ?

P09 - 0000 or 0001 Non zero start

P10 – PAS THR or Both

P11 - 1 to 24 ?

P12 - 0 to 5 ?

P13 - 5 to 12 Magnets on PAS ?

P14 – 1 to 20 ?

P15 - 000.0 to 200.0 goes back to 029.0 when motor is used

P16 - 000001 Mile – Cant change this one

P17 - 0001 or 0002 ?

P18 - 50 to 150 ?

P19 - 0001 or 0002

P2 – Backlight on off or switched.

You need to disconnect the self-learning wires shown in the diagram. The motor turning is what happens when it does the self-learning.

No luck ... I think I don’t get the right parameters into the P numbers .... does anybody know the right parameters forces 24volts motor ?? Can get running by pedaling ... thank you

I disconnected the green cable and it’s stopped turning as you suggested. But no way to make it work by pedaling ..

Without looking at the manual, I'd say that P7 is for the speed sensor to make the LCD show the speed correctly. It should be 1 or 6 normally. What are you using for a speed sensor?
