I have a 97 22’ 454/300 bowrider, and for the last few years I have noticed that when I leave the boat for a week, the battery goes dead. Obviously I have a draw on the battery. I did a test (after reading a thread from last week that Audiofn answered) and left the positive cable connected and disconnected the negative and connected a test light between the battery and cable. The light was as bright as it is when connected directly to the battery. I pulled each fuse one at a time and checked the test light and it lit everytime. I did this hoping it may be in the line at the fuse box. I have no “flooky” characteristics with the whole electrical system, so I am at a loss as to what/where to go from here. Now, this is where I need some OSO brotherly help! WHAT do I do next as far as checking the current draw? I need all suggestions you guys can give me too check. I do have dual batteries with a switch that I turn off now all the time to save my batteries. I always turn off the radio if I am leaving the boat all night. I am also posting this in the tech section also to help me figure this out!
