(PIN 16) BLACK WIRE
Supplies 48 volt input to controller through the red wire to keep capacitors inside the
controller charged. Supplies voltage when key switch is either ON or OFF, if TOW/RUN switch
is in RUN position. Voltage input to controller capacitors is shut off when TOW/RUN switch is
in TOW position.
Pin 2 completes circuit to controller through orange/white wire when TOW/RUN switch is in
RUN position. Activates electronic components in the controller to allow the vehicle to operate.
With the TOW/RUN switch in the RUN position, the key switch ON and the accelerator pedal
depressed (limit switch closed), Pin 3 completes circuit through the green/white wire to
controller, which actuates controller and starts vehicle.
When F&R switch is in FORWARD, Pin 4 completes circuit to controller through white wire to
operate vehicle in forward direction.
When F&R switch is in REVERSE, Pin 5 completes circuit to controller through blue wire to
operate vehicle in reverse direction.
If the vehicle is not charged for three days, the onboard computer powers down the electrical
(PIN 6)
system to reduce battery discharge during long term storage. Pin 6 provides voltage input
YELLOW
WIRE to the OBC when the accelerator pedal is depressed to power-up the system.
Controller varies vehicle ground speed depending on voltage input from the multi-step
(PIN 7)
potentiometer through the yellow/black wire as the accelerator pedal is depressed. 3.5 volts
YEL/BLK
with pedal up, zero volts with pedal fully depressed. Vehicle will not operate if voltage is
WIRE
below 3.0 volts when key switch is turned ON (High Pedal Detect).
Pin 8 completes the negative voltage circuit for the multi-step potentiometer through the
(PIN 8)
WHT/BLK
white/black wire.
WIRE
(PIN 15) Pin 15 supplies a constant 5.0 volts from the controller to the motor speed sensor through the
RED/GRN
red/green wire.
WIRE
Motor speed sensor acts as an electronic tachometer that pulses a voltage signal through the
light green wire at Pin 14 in the controller. This signal tells the controller the vehicle's speed.
When the batteries can accept a regenerative charge, the onboard computer provides a 13-volt
input to the controller which causes the controller to switch from dynamic braking to
regenerative braking.
Pin 12 completes the negative circuit for DB solenoid activating coil through the brown wire,
which closes solenoid contacts during normal operation. Pin 12 shuts off voltage to DB
solenoid during dynamic braking which allows current to go through the resistor coil until
batteries can accept a regenerative charge.
Pin 11 completes the negative circuit for the main solenoid activating coil through blue/white
wire and closes solenoid contacts which allows vehicle to operate. If there is no vehicle
movement when main solenoid engages, Pin 11 shuts off voltage to the solenoid after two
seconds. During normal operation, each time accelerator pedal is released, Pin 11 shuts off
voltage to the solenoid after two seconds.
Pin 10 completes negative circuit for the reverse buzzer through the orange wire. Activates the
reverse buzzer when F&R rocker switch is in the REVERSE position.
Pin 9 provides a constant 5-volt signal to the multi-step potentiometer.
Pin 16 completes the negative circuit for the motor speed sensor through the black wire.
