hi paul, i have an early 2012 ft and am having battery troubles getting less than 8 hours on a 9v and recently getting X? or XX on my rms. SERIAL #: 390E67C5. I have already installed a replacement battery box. I have 3 canisters. I have tried rotating their position. This is a recent development however i the past i frequently got a lost temp probe and found found probe prompts during my dive. The sensor is flush with the nut. The can bus doesnt show any corrosion or anything. What do need to do to fix these issues? Thanks! i love my revo. one of the few things i have ever bought without a shred of buyers remorse. ian
