Sabvoton 72150 Ground shortcut?

[Kisszabo]

Hi All!

I have a little issue with the Sabvoton 72150 controller.
The whole config is:
QS 205 V3 T4; Sabvoton 72150; CT-22 Display; Z6 Throttle;
I have a main switch after the battery, and an "ignition" switch before the controller.
(also the lights, horn, etc can work without the controller)

If i turn it on, the brake light always lights a bit, and the NRM leds are alwas lights on the display... even when it SPORT or ECO mod select. I have Brake check LED, and Reverse check LED, and they are lights a bit too. (see the pictures)

I checked all the wires about 5 times - but always the same:
If the controller turns on, have the problem - if turns off, than everything works fine.
It looks like ground shortcut or something, but very tiny, because only LEDs works.
Anyway - the electric "bike" works fine, i have ride about 150km with it.

have you got any idea what should i check?

Thank you for your help!

(sorry for the poor english)

Can you post your exact wiring diagram? This will help us help you figure out if there is a miswire, since we can't know how you have it all connected without that.
