ranty replacement.

Silicone Heat Transfer Compound:
Before installing the unit, open silicone transfer compound bag (included), spread silicone heat transfer compound on the bottom plate
of the speed controller and proceed to install the unit. (See picture)













A2 Terminal:
Units with A2 terminals (plug break) do not provide an essential function to the vehicle. Installing a unit with no A2 terminal in a vehicle
originally equipped for it will not prevent the vehicle from operating (consult your factory manual for details). If you receive a controller
with the A2 terminal option, and your vehicle is equipped for it, remove the plastic cover (shown in picture below) and connect the A2
(plug break) wire harness terminal. If you choose not to connect it, remove or properly insulate the A2 wire harness.









General Precautions while working on vehicle:

1- Set Switches:
a. Key switch off.
b. Forward/reverse (F&R) switch neutral.
c.
If your vehicle is equipped with a RUN-TOWN / MAINTENANCE switch, place it in the town-maintenance position.

2- Jack-up the vehicle:
a. Some fault conditions can cause the vehicle to run out of control. ALWAYS jack-up the vehicle to get the drive wheels
off the ground before attempting any work on the motor control circuitry.

3- Protect yourself: Electric vehicle batteries can supply very high power and dangerous high-current arcs will occur if they are
short-circuited. Also, charging or discharging lead-acid batteries generate combustible gases, which can build
up in and around the batteries.
a. Always wear safety glasses and follow the battery manufacturers recommendation.
a. Remove watches and jewelry.
b. Use insulated tools.

4- Disconnect the batteries:
a. Always open the battery circuit by disconnecting the cable from the B+ terminal of the battery. Never work on the
motor control circuit with the battery connected.




Preliminary Checks:

1- Inspect the cables and connectors:


Controller Bottom Plate
Heat Transfer Paste

A-2 Terminal a. Look for any indication of corrosion or overheating. High current electrical connections must be clean and tight or they
will overheat. Cables with crimped-on terminals will often corrode and overheat at the point where the terminal is crimped
on to the cable. This can cause the controller blades (B+, B-, M-, A2) to get very hot and even melt the plastic faceplate
on the controller itself. What appears to be an overheated controller may actually be caused by bad cables. Replace any
cables with cracked or burned insulation. Cables with soldered terminals will be far superior to cables with
terminals that are only crimped.

2- Check the motor:
a. Follow the vehicle manufacturers maintenance procedures to verify that the motor is not seized or shorted.
Attaching a new controller to a damaged motor may damage the controller and void the warranty.





Post Installation Checkout:
(This text was partially modified from its original version found on the Curtis PMC Manual)

Prior to Checkout:
-
Put the drive wheels off the ground using jack-stands before beginning the checkout test.
-
Dont let anyone stand in front / behind the vehicle during the checkout.
-
Make sure the key switch is off and the vehicle is in neutral before beginning.
-
Wear safety glasses and use well-insulated tools.

Checkout:
a. Connect the battery. Use voltmeter to verify proper voltage and polarity on the battery
terminals.
b. Check the voltage at the controller B+ and B- bus bars. If your system has a pre-charge
resistor in parallel with the main contactor, you should see approximately 90% of the full
battery voltage. If your system does not have a resistor, temporarily connect one (100 to
200 ohms, 5 watts, or a 100 watt light bulb). The voltage at the controller should rise to
approximately 90% of the full battery voltage.
c.
If A and B do not check out, troubleshoot the wiring connections. Do not turn on the key
switch until the trouble is corrected and A and B check out.
d. If your vehicle is equipped with a Run/Tow-Maintenance switch, return it to the RUN
position. With the forward/reverse switch in neutral, turn on the key switch off. If the motor
runs without the throttle being applied, turn the key switch and recheck the wiring. If the
motor does not run without the throttle applied, proceed to next step with the checkout.
Select direction and slowly apply the throttle, the motor should now respond.
e. Look to see which in direction the wheels are turning. If the wheels are going the wrong
way, turn everything off and interchange the motor field connections.
f.
If you have an HPD (high pedal disable), check it next. Turn off the key switch and
direction switch. Apply the throttle, turn the key switch on, and then select a direction. The
motor should not run. Release the throttle and re-apply it the motor should now run. If
the motor runs before you release the throttle, recheck the wiring.
g. Take the vehicle down off the blocks and drive it in an open area. It should have smooth
acceleration and good top speed.

Note: Unintended Activation of High-Pedal-Disable (HPD)

In controllers equipped with HPD, sudden application of full throttle may activate the HPD feature in systems where the pedal
micro-switch is wired in series with the key switch input to the controller. Normal gradual application of the throttle should not cause this
action.

In case of difficulty:
1- Check battery charge
2- Be sure run/tow maintenance switch (if equipped) is in run position.
3- Check fuses and power to controller and motor.
4- Check operation of main contactor solenoid.
5- Check operation of throttle.
6- Check switches key switch, pedal switch and F&R switch.
7- Check any interlock switches, which may disable operation i.e. charger receptacle inhibit switch.
