Furuno unit will not power up

Question

​I just put my equipment back on my boat after a winter's rest.  
 
The unit doesn't work.  It doesn't power up.  I measured good voltage at the power plug before connecting it to the unit.  What could be wrong?

Solution

​Check for corrosion on your in-line fuse and at your power connection.  
 
You may be measuring the correct voltage in a no current draw situation, however you may be losing the voltage when the unit actually tries to draw power.  
 
The in-line fuse may be corroded on the ends and causing high resistance in the power cable.
