hardwired stuff died while on shore power
Got an Airstream tech question -- not sure if anyone here can assist, but I've never really understood the electrical systems on this trailer as well as I would like, and any help would be much appreciated.
So we're stuck in an auto shop parking lot while we get the truck fixed, and plugged into their outlet (using that adapter-thingy that allows my shore power plug to connect to a regular three-prong household plug). We're clearly getting juice, because my microwave works and I can fire up my laptop using a wall outlet just fine (none of which occur when we're just on the batteries) -- but over the past couple of days, all the hardwired 20-volt stuff (like the lights and the water pump) has slowed/dimmed and now gone out, like we've been battery-only and drained it. Shouldn't all of that have been running on the shore power? Is the fact that we're on what I think equates to 15 amps instead of 30 the problem? Or could it have something to do with the fact that (while renovating), we disconnected the battery cables from the trailer kill-switch and then reconnected them (in order to move the switch into a new piece of furniture) and maybe did something wrong? Have we inadvertently killed the marine batteries? Help!
