I've got an intermittent problem that I believe is due to a bad ground, so I started from the batteries and cleaned all of the connections I could up to the chartplotter which is showing the issue. Not surprisingly, there was some corrosion on the battery connections, the main ground stud, etc.. I did take the cover off of the main 40A circuit breaker (you know, that white cover with the red reset button that is marked "40") and found that the connections were completely corroded. Corrosion was so bad that I could not remove the screws (they were completely rusted). Anyway, I guess my question is: should I leave this CB alone or put in the effort to replace it? I didn't Ohm-out the CB, but my only thought was that maybe the connections are very resistive now and this could be limiting current through that CB....is this possible or am I crazy? Any advice would be greatly appreciated.
Thanks!
Thanks!
