Hi and
to the forum.
It sounds like you definitely have a problem with the Blue Hall Sensor signal voltage as it is not switching between High and Low, but I'm puzzled as to why it is reading more than 7 volts.
I would unplug the Hall Sensor connection and measure the signal voltages on the controller connector to see if the Yellow and Green signal voltages are the same as the Blue
(above 7 volts).If the Blue signal voltage is the only one above 7 volts, it could indicate a problem within the controller.
However, if all three are above 7 volts when unplugged, I suspect that the voltage is simply staying too high because of a failed Hall Sensor inside the motor
(or possibly a break in the wire, or a poor soldered/crimped connection somewhere on the Blue Hall Sensor wire on the motor side of the connector).
If you use a sharp pin/needle to puncture the insulation and measure the voltage on the Blue Hall Sensor wire just after the crimped connector on the motor side this would indicate a poor/broken connection inside the crimped terminal if the voltage was considerably different when measured on the wire itself instead of the crimped connector contact.
Measuring the throttle signal voltage would also indicate that the throttle is working correctly
if the throttle signal voltage stays within the expected voltage range when the throttle is moved between the Maximum Forward and Maximum Reverse position.
