The machine can be converted to foot controls via linkage and the actuators would have to be removed so mechanical linkage can be hooked to valve spools. However the main controller will have to be reprogrammed to non-ACS or the control valve will remain locked. By the time all that is done it would have been cheaper to fix ACS. The actuators have 5 wires, 2 motor wires and 3 sensor wires. If you remove the actuator and look at the plug you will find pin numbers. Pin 1=sensor ground, pin 2=sensor signal, pin 3=sensor 5V input, pin 5= motor -dcv and pin 8= motor +dcv. The sensor in the actuator is a hall effect sensor and the motor works with PWM from the controller. If you try to control the actuator without PWM it will not only control the valve at full stroke but will burn up the motor very quickly. So it is not possible to run actuators without controller. Your valve should have a BICS lock valve that is released by the main controller and receiving inputs from the ACS, this is why you had pressure but no functions, you should also have spool locks but not perfectly sure because Bobcat was going thru lots of changes during that model year.</p></blockquote><p></p>
