Xh18 not reading speed

[Arie Groenenberg]

Hello I have a tongsheng tdz2 with a xh18 display, everything works well including lights front to back, but it doesn't read speed, everything seems to be hooked up correctly, any suggestions?

I assume you have a speed sensor on the rear wheel that uses a magnet connected to a spoke. Make sure the magnet faces the sensor, and that it is close enough to trigger it.
Just yesterday, one of my magnets (I use 2) twisted itself, and wasn't facing the sensor. In my case, it was showing half speed and distance. Got home and realigned it, and all is good.

might check the pins in the connection for the speed sensor as well, one or more could be bent.

I just finished the conversion, it never showed speed from the start, I got about 12 mm between sensor and magnet.

I will check that next weekend, because that's something I haven't looked at, thanks for the suggestion
