Thanks Gary. I'm troubleshooting the system, and need to know what indications I would have when the dash switch is on. On my previous RV ,a Winnebago Journey, the Allison keypad would show "2" when the exhaust brake was on and the throttle was closed. As you know, that indicated that second gear was preselected, and eventually would downshift to 2nd.
On the current coach, when the ex brake switch is on, nothing happens, no indication, nothing...
Guess I'll start at the dash switch and work back from there?
