Who is manufacture of cruise is on fly by wire/electronic Cummins/Allison DP
Who supplies it .Had three toggle switches next to Shift panel.
Idle up/down...on/off...set/resume. It seems to be difficult to gain any info on the system ,troubleshooting,operation or a stand alone diagram. My coach has four diagrams ,one for King cruise used mechanical engine. Three others for my optional M11/4060 with just different wire numbers to those switches.
If I'm idling. (on + set ) idles up to 900 rpm. I understand that's proper. Idle up/down does nothing. When do those work.? When I bought rig a wire was off. Three cruise switches had Lower power main pos. that jumped to all three switches, pulled out of spade ,I fixed that . Unfortunately the speedo quit right before fix so I couldn't test cruise. I have Allison updated output sensor on order.
