Hello! We've just picked up my 'new' 2017 sv650 ..... Flat battery, so connected a booster pack to start it. Everything lit up nicely on first attempt but didn't start. On second attempt, it started and runs fine, however, the display panel (speedo thingy? ) isn't working now and the bike's not charging. Could be two separate issues? Checked the obvious fuses under the seat but is there a sneaky one somewhere else? Any tips or suggestions please?
