Hi I'm new to this forum. Got a 2009 Sprint 1050 and have changed starter relay and battery after it went dead. Same thing has happened with new relay and battery, Anyone got any ideas on what's wrong please?
Welcome Johnnie, it sounds like your charging system isn’t working properly. You need to charge up the battery then put it back on the bike. If you have a multimeter, check the voltage of the battery with the ignition on but bike not running, should be about 12.7 to 13.3V or there abouts. Start the bike and check again, voltage should have gone up to somewhere around 13.8 to 14.5V and should be pretty steady, maybe rising slightly with revs. If it’s not around these values then we’re looking at a fault to investigate. Also, how long was it from when you changed the battery to when it died? Had you ridden it much or was it just stood?
