Anchor chain counter resets after power down


Mohammad Shirloo
 

Our chain counter resets to 78.2 meters whenever it is powered off and on. We reset to zero, when the anchor is up and everything works fine, The issue obviously, is when we go to bring up the anchor, or need to let out more chain or pull some up, after a power cycle, we are back to 78.2 meters, regardless of how much chain we have out. Is there a battery inside the unit for saving the amount of chain out? Other potential sources of the problem?
