Question about Garmin GPSMAP 3210 GPS Receiver

1 Answer

I have a Garmin GPSMAP 3210. Lightening hit my sailboat when the chartplotter was not connected. It blew the 3 amp fuse but not the 1 amp. After replacing the 3 amp fuse I turned on the chartplotter which gave me the intialization screen then went blank, Now it will do nothing. There is 13.22 volts at the power pins. Any idea what the problem is. Is there a fuse inside the chartplotter? Coulf the GPS receiver be destroyed.

If lightning struck that close to the GPS a large EMP was created, EMP stands for Electro Magnetic Pulse, the bottom line is it induces a huge voltage surge into delicate electronics of the GPS and burns out the IC's (intagrated circuit chips), long story short it fries the GPS, I am 100% sure on this.
