Have a 2009 F650GS - wired a Garmin GPS about 3 years ago to the GPS plug on top of battery. It used to act fine, GPS would give the “no power - shutting down” message once the key was turned off and it would power down. Now it has started staying on and attempting to charge once the ignition is off. Only change is that the GPS recently had a large software update… All wiring looks fine still, not sure where to go next with this. Better to just use some type of fuse block?
