Uglider UM36x manual/circuit diagram?

[mrjibbles]

Hi,
I have just been given a UM36x which seems to be fully charged but has a loose connection on the power control unit (if it is called that) on the handle bars, as there seems to be no display.
I wondered where I can get a manual/circuit diagram so I can check out the wiring.
This is my first electric bike so have very limited knowledge on the workings of the bike but fully understand electrics!
Cheers
Giles

Hi, update....after taking the bike for a spin, the display dropped straight away from full to empty (and even then only flashed occasionally). It also went straight to full and back to empty a few times too.
Any information gratefully received!
