[QUOTE="Cyclepath, post: 1453380, member: 78971"] Yep, sounds like you battery may not be taking the charge you're trying to give it. If the bike was not running, and your static voltage measurement was still jumping around, it could be you have some low resistance / mild short in the harness draining down the battery too (?). How about the bike's own charging circuit components? Alternator, rectifier, regulator ? Decades ago, I had a '77 RD400 that seemed to suffer a similar issue. On that admittedly smaller / much simpler bike, it turned out to be its rectifier [draining away current to ground] - so my battery went flat almost every day until I replaced the rectifier. [/QUOTE]
