Maybe in the instuction book that came with the coach from Ford you can find a drawing of fuse panel layout. 98% will be Ford power supplies, however a few will marked on the dwg as " reserved for end user" or coach builder etc, one of those is what you are looking for. Our rig is a 2010 design built in 2011 for a 2012 coach. That cig lighter is always hot with or without the ign. key, not like cars,. Your problem maybe dowm stream of the fuse like corroded connection, best to star at the source.
