Type 2 Linear Drive Not Actuating

Chuck:
I determined by following the FAQ directions that the electric motor in the pump is bad. Since I cannot find a motor I guess I'm going to have to replace the pump assembly. Is there any special hydraulic fluid I should use?

On a similar note - I also found out that the voltage out of the course computer is a 0V - 12V pulse-modulated (duty cycle) signal at 19 Hz. When reading the signal with a digital voltmeter one will see the average of the signal at 6V. You have to use an oscilloscope to see the duty cycle.
