In the programmer's Monitor Menu, scroll down to observe the status of the
switches: mode, reverse, and push. Plug in the battery charger to verify the
Inhibit input status. Cycle each input in turn, observing the programmer. The
programmer should display the correct status for each input.
Similarly, check the throttle and speed limit pot inputs. The programmer
should display the correct value for each input.
Verify that all options, such as high pedal disable (HPD) and seat lift,
are as desired. To verify operation of the seat lift function, put the programmer
into Parameters mode and set the VSL parameter On; if VSL is not an option,
you will need to unplug the programmer and plug in the seat lift connector in
order to verify seat lift operation.

If the cold resistance of the traction motor in your application is known, you
can enter this value, in milliohms, for the motor resistance
and proceed to Step 3. However, we strongly recommend that instead of using
the theoretical value provided by the motor manufacturer you use the actual
value as determined in the following procedure. It is very important that the
motor resistance parameter be set accurately. The correct value for
determined as follows.
4-a. Position the vehicle up against a wall, high curb, or some other
immovable object.
4-b. Plug the programmer into the controller and turn on the key-
switch.
4-c. In the programmer's Parameters Menu, set the
to "30" (30 amps).
4-d. In the Monitor Menu, scroll down to display the Motor R field.
4-e. With the speed limit pot set at maximum, apply the throttle full
forward, driving the vehicle against the immovable object.
4-f. Observe the Motor R value displayed in the Monitor Menu.
4-g. Select the Parameters Menu, where
