Hi! I picked up a 2013 Salem Hemisphere from a couple who got from someone else and they lived in it while building their home. My issue should be simple. I need to locate the power switch so that I can turn it on to allow the converter to charge the batteries while I'm on shore power. I've looked under and everywhere I could think of inside and absolutely no luck. I asked the previous owners and they have no clue. Any ideas?? Thank you!
