I'm having a battle with a new Garmin Zumo 350 on my R1200R or more correctly the wiring harness between the bikes battery and the cradle the GPS mounts to.
The issue with this harness is that the power regulator (transformer) in the harness which converts the bikes 12 volt to 5 volt, under certain circumstances continues to drawer power from my bike?s battery and over a three day period will drain the bikes battery completely.
NOTE: Let me be very clear here ? this only occurs when the GPS IS NOT ATTACHED and the motorcycles ignition is switched off.
So the circumstances are ?
- GPS not fitted to cradle.
- Bike is run as usual.
- Bike ignition is switched off.
- Harness continues to drawer power from the bikes CANBUS system.
The wiring harness is attached as per the manufacturer?s instructions.
It is interesting to note that if the GPS is in the cradle and the motorcycle?s ignition is switched off after a ride and then the GPS is removed ? the issue does not occur. It is only when the GPS is not attached.
I'm no electrical genius but I can't see how something not connected to a device can possibly suck the bike's battery dry. If the little black box which steps the power down from 12 to 5 volts is "still doing something" - where does the power go?
Anyone else had this issue or have any idea what may be going on?
