On my bus the auto shut down and the alarms were both disabled. The first thing I did when i got the bus was to re-establish the low air audible alarm buzzer, but I haven't done anything with the other alarms (other than buy new diodes so I could fix it all up). I think a good compromise is to disable the auto shut down, but make very sure the audible alarm buzzer is hooked up and working for low air, low oil pressure and high water temperature, along with their respective warning dash lights.
normally, I would have to agree with you on this. However, my experience with my own coach has shown me that the buzzer is not always trustworthy. In fact, right after my problem with my air compressor, while I was diagnosing the problem, I had drained most of the air from the system, but when I turned on the bus to start it back up and see if it was pumping, the buzzer did not go off. The lights on the dash were going, but bulbs can and do burn out, and depending on the orientation of you steering wheel spoke, you may not see the light (my punch list has changing the position of the steering wheel because of this, but it has not risen to the top of the priority list... or I just keep forgetting to do it).
I can guarantee you it will get your attention when the engine shuts off!
The shutdown system is designed such that it can be overridden by holding in the start button so you are not necessarily stranded when it shuts down the engine.
And Bryce, I don't take offense or feel you were demeaning in your post. I have always said from day one of this hobby that I will do my best to document my successes and also my failures so that those around me and those coming after me can learn from me. If it means I look like a fool, well, then I guess there must be some truth to it. I've never claimed to be an expert at any of this, and while I think I'm probably more skilled at some of this than the average bear, it's all a learning experience for me, too. That's why I keep JD's number on speed dial
