Section 4 - Troubleshooting
1. Open the connection between the controller and the
PCPaK utility. On the left side of the screen, select the
“test” section under the “traction” pull down. This screen
will
display the inputs the controller is observing at that time
(Figure 4-3).
2. With the Forward / Reverse knob set to Neutral, slowly press
the accelerator pedal. The “Accelerator Push” value
should
rise in value from 0-100% smoothly as you press the pedal
(Figure 4-4). If the value does not change, the controller is
not receiving input from the accelerator control device
(potentiometer or linear accelerator device). Check all cable
and wire connections regarding the accelerator control
device. If the value does rise, but not to 100%, adjust the
accelerator cable that attaches to the accelerator device.
