To figure out where your gremlin is, we may need to get another helpful 2nd gen owner to make those same measurements that you have made on a healthy bike, ideally with the same test equipment.I'm also now suspect of the .7 ohm measurement. 7 amps (or more with engine running)) through a .7 ohm resistance would result in a 5 volt drop, not a few millivolts.
