Hi gentlemen just changed battery and notice my fuel gauge dosent sweep or move and fuel light is on with full tank any info would be helpful cheers 2012 nrs
Does the IM (instrument module) WOW? ...
Turn the ignition switch to ACC. The instrument background lights should turn on, gauge needles should sweep through full range and back, and all LEDs controlled by serial data (battery, security, coolant temperature, and CEL) should light up.​
If you fail the WOW test, check the ACCY fuse in the fuse block under the passenger pillion.

If you pass the WOW test and still see no fuel gauge motion, check the connector under the seat for the sonar level sensor. It's a separate connector with three wires (O/W, Y/W, BK/GR).

Also, to avoid blown fuses and other electrical problems, pull the MAIN fuse under the upper right side cover before working on the bike.

I had the same problem last year with my 2014 v-rod muscle. Mine was the Fuel Sending Unit. I went ahead and replaced the part...and as of now, the fuel gauge works great.

Part No#: 75310-07

Auto part Line art Diagram Automotive exterior Automotive fuel system


Video shows how to replace it yourself:

Someone is selling one on ebay:
