Thanks for getting back to me. The screen is blank. I checked the fuse and it was good, but replaced it anyway. I will try to check the bonding when the weather cools down (100 degrees is in the forecast for this weekend). May be easier to just replace it if not too expensive.
Fortunately, the area I boat in has a mud or sand bottom, so grounding does not do any damage as long as I go slow in areas that I know are shallow.
