mystery battery drain FOUND

[Curtis-79MH]

Yee haw!!
Here is the short version: I have a 79 MH, 28 footer. Something has been pulling on the battery and draining it, it has stumped everyone, even my friend Peter from Austin but I found the rascal. And is my wife ever happy about it!!
It turned out to be the horn fuse in the main chassis fuse box. We removed that fuse and SURPRISE no drain. But we also found out the horn fuse controls the automatic coach step....So the next thing we will do is isolate the problem.
But for now does anyone know WHAT ELSE the horn fuse might be linked with??
Cheers everyone!! To be continued....this is very exciting news,
Curtis

Here is another drainer to watch out for:
In our 79 trailer, the lamps in the storage compartments are easily turned on by stowing extension cords and water hoses. In the daylite they are easy to miss.
