I have a 7753 with the BOSS controller. The dealer is clueless on how it works. There was like only two of them made. The BOSS controller will not pull in the auxiliary hydraulic solenoids. I have the solenoids hotwired so to speak. It is looking like the controller is not pulling in the solenoids. But I am not sure if it is because of some interlock not being satisfied. I have the manual and where I am headed is, what is the auxiliary control switch suppose to do? Anybody else had the opportunity to do any troubleshoot on the system?
