Have not had that issue with the chassis battery switch. I’ve used it twice since we’ve had the coach since new, both times when switching out chassis batteries. Bad chassis battery switch or relay?????
On the slides, that “emergency button” is a fault reset that then allows you to bring in the slides by operating both the in and out buttons at the same time. In our experience the fault light is triggered by a slide sensor not properly registering complete extension of the slides. This happens a couple of times a year and FWIW usually after a hot day of travel and in hot weather. Never had to try chassis battery cutoff to reset the fault light, always unscrewed the control panel for the slide, pressed the fault reset microswitch and brought the slide in. Next operation of slide is uneventful.
