Speed Control Circuit, Continued:
The potentiometer detects accelerator pedal position and sends a corresponding voltage signal to the con-
troller. As the accelerator pedal is depressed, voltage from the potentiometer changes, causing the controller
to send longer pulses to the motor and thereby increasing vehicle speed.
The Speed Control Circuit Consists of:
• The potentiometer.
• The controller.
• The Z9 Transistor located inside the controller.
• The Z10 Transistor located inside the controller.
• The 18 gauge yellow wire from the potentiometer to Z9 position on the Z plug/controller.
• The 18 gauge white/black wire from the potentiometer to the B- terminal on the controller.
• The 18 gauge purple wire from the potentiometer to Z10 position on the Z Plug/controller.
MOTOR SPEED SENSOR CONTROL CIRCUIT (FIGURE 21-12)
The Motor Speed Sensor Control Circuit monitors motor rpm to determine vehicle ground speed, and based
on vehicle ground speed, it determines when motor braking will be activated.
The Motor Speed Sensor Control Circuit consists of:
• The motor speed sensor located inside the motor.
• The Z13 transistor located inside the controller.
• The Z14 transistor located inside the controller.
• The 18 gauge red wire from the motor speed sensor to the Z13 position on the Z plug/controller.
• The 18 gauge green wire from the motor speed sensor to the Z14 position on the Z plug/controller.
• The 18 gauge black wire from the motor speed sensor to the B- terminal on the controller.
