First post, so apologize if not in correct category. We recently purchased a 2016 Shadow Cruiser 240 BHS. I'm having some electrical problems and can't find a downloadable guide to show me where everything is located. Is this common? Any ideas where I could look for such information? The problem is that everything works when plugged into shore power. Unplug and nothing works. I replaced batteries and they show charged, 13.55 and 13.54, likely from the solar panels. Any ideas where to start?
