Odd Electrical Issue with the Sea Level Monitor

Just an FYI for anyone who looses the digital readout on their Sea Level monitor.  I was testing out how well the solar panels would maintain the battery charge with just about everything but the fridge on.  Suddenly, the display on the Sea Level stopped working.  The water pump still worked...there was still power to the unit for the little light to indicate when the pump was on, but no display for battery, fresh, grey or black tanks.  I tested the fuse (#4 10amp) and it was good.  What I didn't do was leave it out for 1 minute.  So, if this happens to you, pull the #4 fuse, leave it out for a minute or so, and plug it back in.  The root cause was static electricity build-up...probably from me pushing the battery button every couple minutes to check the level.  All is well now.  BTW, this information is in the Sea Level manual.
