Does it have an ITS throttle or is it a pot-box type throttle?

What model controller?

Does it run smooth at full throttle?

What is the voltage on the black wire when pedal is pushed just far enough to make solenoid click?

What is the voltage on the black wire when pedal is pushed halfway (were it jerks)?

What is the voltage on the black wire when pedal is pushed to the floor?

What is the voltage on the white wire when pedal is pushed just far enough to make solenoid click?

What is the voltage on the white wire when pedal is pushed halfway (were it jerks)?

What is the voltage on the white wire when pedal is pushed to the floor?
