Just installed a new battery 3 weeks ago in my 2008 1200L. Now bike won't start, all it is doing is making a clicking noise. Put the volt meter on the battery with bike off and it is reading 12.60. When trying to start bike it drops down to around 7.7 amps. The battery has a full charge but won't crank bike over. Does this mean my battery is no good or could there be something else wrong. Only 6000 miles on bike.
