"All My boat battery will not
"All My boat battery will not stay charged. I put a new battery and with in a week at the dock it is dead. Something is pulling power. I put a cut of switch in the powerline of my fish finder because I thought thats what it was. I charge the battery and it will work but while parked it dies. If I use it day after day its fine, but once parked for about a week it drains. How can I find whats drawing power?"
