I recently experienced a loss of wind direction data on my B&G Hydra while on passage.  Wind speed continued to report normally, but all direction related data boxes displayed a flat line.  A reboot of the Hydra system at the breaker corrected the problem, but it occurred again later in the day.  I plan to disconnect, treat with CorrosionX, and reconnect the wires at the black box and at the junction below the mast step. 

Has anyone had a similar experience?  Aside from checking connections, does anyone have a suggestion other than finding a technician to look at it?

Thanks,

John
