Model number breakdown, for example the { NCX300-DCS } is broken down as:
- NCX - Family name
- 300 - First three digits = amperage, = 300 Amp model
- xxx-DCS - "Option Identifiers" = Throttle Setting for Factory programming of DCS car,
(xxx-PDS is the Power Drive System programming)
The NCX product line are Non-Programmable Controllers used with
SEPARATELY EXCITED Wound Motors, Commonly called SHUNT wound
motors. These units are designed specifically for factory equipped golf cars.
Customers demanded higher quality after-market replacement with a
warranty instead of "REBUILT USED Controllers". Alltrax stepped up and
designed a NEW product with a NEW warranty, the NCX Non-Programmable
controllers. A cost effective solution to replace your aging or damaged
stock controller without buying a "rebuilt controller".
Features include:
- Factory Programmed (These are not field programmable by the
customer)
- Integrated anodized heat-sink with multi bolt pattern for flexibility
- Fully encapsulated epoxy fill - environmentally rugged design
- Advanced MOSFET power transistor design for excellent efficiency
and power transfer
- 1/2 Speed reverse
- Reverse Beeper Output

Did you know?
> The ALLTRAX the NCX
STOCK Controllers only
work with OEM factory
motors?
Using this controller on a
"performance motor"
designed for Speed or
Torque will cause a failure
and void the warranty.
Did you know?
> Shunt wound motors
have the Field and
Armature coils connected
Separately?
The NCX provides the
Separately Excited Field
current and Armature
current in relation to a
Field Excitation map
particular to the motor
manufacturers design
requirements.
Verify the motor is stock
before installing the NCX.
If the motor is modified,
the DCX product must be
used.
Note: The controllers has one current output level, the mechanical drawings are shown below.
>The NCX300 replace the Curtis 1204 short heat sink at 6.5" in length (165.1mm)

NCX Wiring Diagram:
An example of the inputs and outputs are shown. Click on the image to
enlarge. This diagram is also shown on the NCX Mini-Manual
Doc100-015-A_NCX-Mini-Manual.pdf
LED Status Indicator:
The LED located on the front of the unit provides status of the units operation
and used for troubleshooting.
The LED Blink Codes occur at power up, the number of green blinks indicates
the throttle configuration:
- 4 Green LED flashes = EZ-GO inductive (ITS)
Normal display status:
- Solid Green: Controller ready to run
- Solid Red: Controller in programming mode (not for field use)
- Solid Yellow: Controller throttle is wide open, controller is supplying
max output, and is not in current limit.
Trouble Shooting:
Error code display:# of RED blinks indicates any error conditions that might
exist:
1 Red = Throttle Position Sensor Over Range. Check for open wires.
2 Red = Under Temperature. Controller below -25C
3 Red = HPD. Throttle hasn't gone to zero during this power on cycle.
4 Red = Over Temperature. Controller over 95C
5 Red = Open Field
6 Red = Battery Under Voltage detected. Battery V < under voltage slider
7 Red = Battery Over Voltage detected. Battery V > over voltage slider

NCX Product are for Factory Motors Only:
These units are designed for OEM (Original Equipment Manufacturers) stock
replacement controllers for stock cars with stock motors only. With a peak
current rating they are not designed for lifted or high performance vehicles.
The design follows the motor manufacturers current and power
recommendations.
For a high performance controller application - Please order our DCX motor
controllers. The NCX controllers are not field programmable and must be
ordered for the exact car you are installing them in. (DCS or PDS only)
For more information see our
Document Depot:

DCS Models:
Uses standard 9 pin wire harness. Plug the stock wire harness onto
the pins on the front of the controller.
PDS Models:
Uses our PDXA harness (included):
Connect the 10 pin and two 4 pin connectors to the matching connectors
on the stock wire harness.
Note: The 4 pin motor speed connector from the motor is not used in this
application.
Fits under the Stock Cover!
