Same thing basically happened to me on my wife's xb9, had battery readings all over the place, intermittent charge problems, went dead them work, ped, shut off onme a few times, with the help of Cooter and Silverider they helped a lot with it, found out mine was a voltage regulator failure, had it replaced and runs great ever since, just an FYI.
There are some of my posts on the forum if you want Togo back and reference them
