Step light on while battery switches off?
When our toilet died on our first long trip a couple weeks ago, we shut off all the power hoping to reset the commode. I noticed that little orange light above the steps was still on even though we had disconnected shore power and turned off the battery isolation switches for both the truck and cabin. So how can that be? Is it just the oddball thing wired in between the battery and isolation switch? If so though, what other things are wired like that and how are we supposed to truly isolate the batteries for storage?
