It is very important to know where the 5 grounds are located on your VRODS. I highly recommend you clean and torque them to spec, over time them become dirty and in some cases loose causing problems.
To do this procedure consult your bikes owners manual or better yet the shop manual as that will give you the step by step instructions on how to do it. This video was made to show the locations of the 5 battery grounds.
Make sure you remove the 40amp maxi-fuse before attempting to do this!
