Question about Magellan RoadMate 700 GPS Receiver
One of the wires in your power cord could be broken and contacting intermittently. If you have the
a/c adapter, see if you can power up with that. If you know someone
else with a working Magellan, you could borrow his cord to test your
If not, check the car adapter with a continuity tester. Put one tester probe on one of the side springs of the car plug and the other probe on the outside metal of the GPS plug. If that shows continuity, place one tester probe on the end tip of the car plug and the other inside the the GPS plug.
If either of those do not show continuity, first take apart the auto side of the cord. Check the fuse and the wire to contact solder joints. If they seem okay, carefully cut back the molded plastic from the GPS end and examine the wire to solder joints. If any are broken, replace the cord or resolder the joints.
