Ok, i'm almost sure i have a problem whith the 5v power supply: if i connect the hall sensor, after few seconds, i have the usual failure in the 5v line; so i disconnected everithing (pas, hall and brakes) and i let connected just the throttle and phases, and i run the motor, while measuring the 5v line of the throttle with a multimeter.
In this way it seemed me to work fine, except from some power failure which happened sometimes, but which last just for a moment, and if i let the throttle and then push it again it works: i thought it was due to the lacking of the hall sensor (even if in fact, my controller should work well sensorless) but checking the voltage with the multimeter i found out that this sudden failure are due to the instability of the power line (oscillating from 3 to 5v).
To better explain myself, my 5v always fails, but when the hall is connected the failure is irreversible until i power everything off and on, while if is connected just to the throttle, it fails, but after a moment it works again.
I tried to use(switching) the 3 power line i have (pas, throttle and hall), but they all behave the same, with a transient failure if connected to the throttle and a permanent failure if connected to the hall.
Next test will be to power every 5v line with an external 5v battery, this way maybe i'll be able to use the throttle without failure... we will see.
So i think i'll have to try to repair my controller 5v line (help would be really appreciated with this) or to buy another controller (maybe a better one which can use the pas and the throttle TOGETHER, since i live in Europe, can you suggest some controller with this characteristics?)
