When I store my coach, I turn off all the interior lights. Invariably, when I return days or weeks later, most of the interior lights are on. Today, I took the coach in for the Aqua-hot pump recall. As soon as I started the generator, the same lights came on. It doesn't seem to matter whether I turn the lights off individually or with the light master switch. Same result. Thankfully, I can plug into 20 amp at storage facility. Any ideas??
