Another DAH! moment

[01RAMer]

Been plugging in my RV periodically throughout the winter, so I wouldn't have to take the battery out. Checked the battery the other day while getting it ready for inspection and the battery was dead. Plugged in the RV and took a voltage reading agross the poles and nothing, then it dawned on me, I hadn't turned on the battery disconect switch, nor did I over the winter. Flipped the switch and had voltage.

Moral of the story, don't forget to turn the switch on.
