I have a 2008 Southwind on a Ford chassis. My battery went dead sometime over the past few weeks. Charged it up and monitored. The voltage dropped about a 3rd of a volt over night. Disconnected the battery and found a 1/2 amp draw. Process of elimination found fuse 4 was the culprit. According to the owners manual fuse 4 is the instument cluster. I have tried everything I can think of and it appears all systems are working. The cluster lights up all indicators work. I just can't find what this fuse feeds. Any help would be appreciated.
