Hi , im Peter from Netherlands.
My e scooter, djjd cashmere , drives fine. Everything work well, but no speed signal to my digital display, speedo meter.
Al other functions on display works okay.
May be its from that the scooter was new, cause on odo meter also no km noted.
I checked the wirring, and the white cable, with a black mark goes to Pin 17 , at the 30 pin connector , from the controller.
I checked ofcourse the cable, the cable is okay.
When i put at the cable for example 12 v, my digital speedometer works okay.
So im almost sure, there is no output at pin 17.
Also checked the other wirring , hall sensor, throthle , and more, all works normally.
Anyone any advise here ?

Ich kann Deutsch lesen, aber nicht besonders gut schreiben

Hallo,

have You checked the controller singnal on this white/marked black-line, when the rear wheel is turned by hand?
Maybe there is the (normal) pulse signal on this line, but it is wrong connected to the line-in for voltage signal in the display. Cross-check will be a pulsed connection of the 12Volt-testvoltage, if this shows a different reaction of the display. Standard displays normaly have two line-in possibilities (pulse signal or voltage signal), when there ist no digital communication.
Viele Grüße
