After two failed attempts to get the coach in for it's MOT, I've established that we have a problem with the 'fly by wire' throttle/cruise system. Thanks to Simon at Travelworld for his help in getting the coach driveable at least to get it in for the MOT (passed) without too much drama, but I still have a non/partially working system. The Monaco uses a Cruise King fly by wire which basically consists of a three wire throttle which sends information to the circuit board on the Cruise King which in turn interfaces with the ECM and (ultimately) gearbox ECM and finally tells the Actuator (stepper motor) what to do with the throttle linkage. It seems that the actuator is 'sticking' and needs to have a kick start in order to work which would indicate that the brushes are worn or dirty. All of the electronics seem to be functioning OK (the LED's sealed inside the box (go figure!) all do what they appear to have to do to indicate that the operation is normal) but the stepper motor SEEMS to be the stumbling block. Has anybody had any experience of this system (Cruise King 2600), does anybody have a spare in their shed, does anybody know anybody who definitely has the ability to diagnose/fix the problem, has anybody had experience of replacing (retro fitting) an alternative system? Desperate help needed on this one please. Cruise King can ship a replacement motor/actuator (exhorbitant price plus shipping), have been offered a retro-fit alternative by someone 'who has never been beaten' by this type of problem. Concerns: Will a new actuator prompt the failure of the circuit board (based on experience of other similar issues)? Can the retro-fit get around of the complex requirements of the communication with the ECM's of the engine management and/or gearbox? Hmmmmm! The whole kit and kaboodle is fitted to our 1996 Monaco Windsor and was only fitted to Monaco coaches for two years before being replaced with (?????). Your thoughts would be appreciated.
