I recently bought a 2006 2275FSI w/ Sea Legs from an individual. He told me the stereo worked but he disconnected it because it ran down the battery. He told me the Lawrence radio worked but he disconnected it because it ran down the battery. He told me the power anchor winches worked but he disconnected them because he used the Sea Legs and...you guessed it...they ran down the battery. I have no idea where he disconnected these devices and he is not responding to my requests for information. Where should I start?
