i got my bike yesterday, it's a 93 suzuki across. i've been riding it round the backstreets yesterday and today, but once yesterday and now again today i had to jump it with a jump pack. when it appears flat, the first crank i can hear the starter spin, but it seems it doesn't have enough go to start it, the second and from then on it clicks. i got the multi meter out, and the readings across the battery are unstarted: 12.8V but another reading showed down to 12.5V idling: 12.9-13.3V reving to 5k: ~14V the battery isn't bulged or anything obviously faulty, and it's a yuasa YTX9-BS (maintenance free) a if that makes any difference. i'm going to leave the battery disconnected overnight to see if the voltage dips any lower. but from this info, im' leaning towards dead battery rather than alt or r/r. can anyone give any insight before i drop coin on a new one?
