[QUOTE="TriHonu, post: 89293, member: 897"]   Back to your original post: In summary here are my questions: 1. Should the "up/down" switches on the control levers reverse the hydraulic flow when pressed from up to down & vice-versa?? - [COLOR=blue] No. The wiring harness on the boom is connected to an Attachment Control kit. Bobcat has produced at least 3 versions of the "kit" over the years. The early 7 pin kit was connected to the optional switches on the steering lever handles. The Right Handle's Trigger Switch and Front Left-Right rocker switch are used to control the Aux hydraulic circuit. This harness simply provided switched 12v power to the pins in the electrical connector. This allowed attachments to have electrical solenoid valves controlling multiple hydraulic circuits on an attachment. Many of these attachments used an open center valve and you put the loader Aux Hydraulics in Constant Flow mode that supplied continuous flow through the attachment control valve and back to the loader reservoir. You would then control the attachment with the other control handle switches. The next system was the 14 pin which you can read about in the links I posted in my first post. The newest 7pin system is a major change from the previous 2 systems. This system no longer provides switched 12v power. The new system is based on controller area network (CAN bus). It is basically a computer network that allows the computer in the loader to communicate with a microprocessor controller on the attachment. The wires are carrying data that tells the loader what attachment is connected and allows the loader to configure itself and tells the valves on the attachment when and how to operate via the operators signals from the switches on the control handles.[/COLOR] 2.
